Releases

Each Cefrium version, the CEF and Chromium upstream it tracks, and what changed. Tap a release to expand its notes.

Cefrium tracks upstream CEF release branches. Each release is built from a specific CEF branch and the Chromium revision it pins, so the Chromium security fixes in that revision are present in the corresponding Cefrium release. Upstream security updates are incorporated into the next release rather than backported. Maintained best-effort, in the tradition of upstream CEF; no SLA beyond what is stated here.

Which version, and where

VersionEngineAvailable fromUse it?
0.9.4 Chromium 154.0.8037.98
CEF branch 8037
Maven Central and the Codeberg registry Yes. Carries both arm64-v8a and x86_64, so it runs on a device and on an emulator, and both cefrium-sdk and cefrium-sdk-libre exist.
0.9.0 - 0.9.3 Chromium 152.0.7977.82
(0.9.3: 154.0.8037.98)
Codeberg registry only — never reached Maven Central No. They cannot be pinned from Central, and 0.9.3 was built for arm64-v8a alone, so it does not run on an x86_64 emulator and has no cefrium-sdk-libre. Everything in them is in 0.9.4.
0.8.1 - 0.8.9 Chromium 149 - 152 Maven Central, permanently Only if you are pinned to one. They carry an older engine and therefore older Chromium security fixes.

Why Central's version list has a gap. It jumps from 0.8.9 to 0.9.4 because 0.9.0 to 0.9.3 were published to the Codeberg registry only. Maven Central is immutable and append-only, so those versions can never be added retroactively, and no published version can be withdrawn or marked deprecated. An older version staying resolvable is a property of Central, not an endorsement: always check which engine a version carries — each release below states its Chromium revision, and from 0.9.4 the published POM carries it too, as cefrium.chromium.version.

Each release also ships an SBOM declaring the embedded engine version and a NOTICE listing every bundled third-party licence, attached to its Codeberg release.

0.9.4 CEF 8037 Chromium 154.0.8037.98 2026-10-07 Maven
Fixed
  • Back on Maven Central, and with every ABI again. 0.9.0 through 0.9.3 were published to the Codeberg registry only, so they were a 404 on Maven Central -- which is where adopters resolve from, since the Codeberg mirror keeps only the latest version and cannot be pinned. Central had served nothing since 0.8.9. On top of that, 0.9.3 was cut for arm64-v8a alone, so it could not run on an x86_64 emulator and published no cefrium-sdk-libre coordinate at all. 0.9.4 restores the full matrix (codecs/libre x arm64/x86_64) on both channels.
  • Two guards so neither failure can recur silently. cut-release.sh now refuses at the publish phase when the variant matrix is incomplete, naming what would be missing, and it has a central phase that fails when the Central token is absent rather than quietly shipping to Codeberg only. The second one matters because Maven versions are immutable: a release that misses a channel or an ABI cannot be topped up afterwards.
  • Consumer docs no longer advertise a version the recommended repository does not serve, and no longer promise x86_64 for a release that lacks it.
0.9.3 CEF 8037 Chromium 154.0.8037.98 2026-10-07 superseded
Changed
  • Engine bumped two milestones. CEF has no 153 branch, so this moves 152 -> 154 in one step. Debian's chromium is on 154.0.8037.92 and the CEF branch pins .98, so version parity (the mechanism by which this port inherits CVE fixes) is satisfied with room to spare. Nine upstream API changes had to be adapted, the notable ones for consumers being an OSR surface-embedding change and a new InterceptNavigationDelegateClient.isTabInPopup() that the SDK now implements -- answering false, because no Cefrium browser is ever a popup window, and answering true would have silently disabled the external-scheme hand-off (intent://, market://, tel://) shipped in 0.8.8.
  • Behaviour change -- the engine no longer queries Google's time service by default. See the entry below; this is the one place Cefrium deliberately diverges from Chromium's own default.
  • The engine now registers only the ten component-updater components this embedding actually uses, instead of inheriting Chrome's full list of about twenty. Validated on device: the ten dropped ones no longer register, every kept one still arrives, and certificate revocation data still updates. See the FEATURE-067 entries below.
Fixed
  • A stale checked-in JNI registration would have crashed any consumer of this release on its first child-process launch (NoSuchMethodError on SysUtils.hasLargeProcessCountSupport, new in 154). 107 JNI methods were added and 70 removed since 152. The release gate already checked for this; the build now checks too, so a dev build fails on drift rather than producing an AAR that only breaks on a device.
Also in this release
  • The com.cefrium Gradle plugin is now compiled to JVM 17 bytecode (class-file 61) instead of inheriting the build JDK's class-file 69. The plugin is plain Groovy against the Gradle API and needs nothing newer; shipping it as Java-25 bytecode forced every consumer onto JDK 25 merely to *load* the plugin during Gradle's configuration phase, which is where the confusing Unsupported class file major version 69 first appears. 17 is the floor Gradle 9 and AGP 9 already require. This does not change the SDK's requirements: cefrium-sdk still ships Java-25 bytecode and still needs JDK 25 / Gradle 9.7.1 / AGP 9.4 / compileSdk 37.
  • Passkeys: route a modal get() carrying allowCredentials to the Android Credential Manager instead of Play Services. Chromium routes such requests straight to Play Services ("non-discoverable allowlist"), which is a Chrome+GMS assumption: for an embedder the passkeys live in a third-party provider that GMS knows nothing about, so Play Services finds no match and the request falls through to the GMSCore hybrid flow (the "check Bluetooth" error page) without ever offering the provider. (patch android/webauthn_3pp_get_credman_routing)
  • Passkeys: declare the caller origin on Credential Manager requests. Chromium applies setOrigin() only from a CredManRequestDecorator that just Chrome registers via ServiceLoader, so an embedder never declared it; CredMan then treated the request as first-party from the app's own package and providers looked for credentials belonging to the app rather than the page's relying party. Affects both get and create. (patch android/webauthn_credman_embedder_origin) NOTE: with both fixes the request now reaches third-party providers correctly, but releasing an EXISTING passkey additionally requires the app to be on the platform's privileged-browser allowlist -- see FEATURES-CEFRIUM.md.
  • Fix passkey / WebAuthn not offering third-party providers (Proton Pass, etc.) in the browser. The per-WebContents CHROME_3PP_ENABLED WebAuthn mode (required for the CredMan path's security checks to pass) was set inside the Autofill try/catch; AutofillProvider construction throws on some OEM ROMs (MIUI/Xiaomi, some tablets), which silently left WebAuthn in the global BROWSER mode so CredMan (and thus Proton Pass) was never invoked. Decoupled into its own try/catch. Validated on device: webauthn.io registration now shows the Proton Pass sheet. (FEATURE-064 follow-up)
  • Behaviour change -- the engine no longer queries Google's time service by default. Chromium enables NetworkTimeServiceQuerying on Android, which makes roughly one request a day to http://clients2.google.com/time/1/current. Its only purpose is to notice a badly set device clock so that a certificate error can be explained as a clock problem rather than an expired certificate; it carries no identifier and no security data, and Android devices normally get the clock from the carrier or NTP. The SDK now applies --disable-features=NetworkTimeServiceQuerying by default, so that call is gone. Certificate validation is unaffected. Restore upstream behaviour with Cefrium.setNetworkTimeQueriesEnabled(true) before the first browser is created -- worth doing if your hardware has no dependable clock source (no cellular modem and no NTP reachability, or an RTC with no battery), where a clock far enough off to break HTTPS is a real support case. Decision note: implemented as the upstream switch rather than by patching the feature's default, so an embedder can still choose and the behaviour survives engine bumps without a patch to carry. (FEATURE-067)
  • New API to control what the engine does on the network in the background, with the two requests given opposite defaults on purpose: Cefrium.setComponentUpdatesEnabled(boolean) / areComponentUpdatesEnabled() and Cefrium.setNetworkTimeQueriesEnabled(boolean) / areNetworkTimeQueriesEnabled(). Both must be called before the engine initializes; afterwards they are ignored and log a warning. Component updates stay on by default because they are a security feed, not telemetry -- the channel that delivers certificate revocation (CRLSet), Certificate Transparency metadata, the dangerous-download file-type policy, TLS error diagnostics, Trust Token key commitments, First-Party Sets and the subresource filtering ruleset. Disabling them freezes all of that at the SDK version you shipped, and the failure mode is silent, so it is an opt-out intended for air-gapped, metered-network and compliance-constrained deployments that accept pinning their security data to a release. Both are Chromium's own switches, and setting disable-features merges with any value already on the command line instead of overwriting it. See FEATURES-CEFRIUM.md and <https://cefrium.com/guides/network-behaviour/>. (FEATURE-067)
0.9.2 CEF 7977 Chromium 152.0.7977.82 2026-09-24 superseded
Added
  • OSR text-selection copy/cut/paste quick menu (windowless). Long-pressing text in an off-screen browser now selects a word and shows a Cut/Copy/Paste menu via CefriumRenderHandler.onQuickMenu + QuickMenuCallback; CEF performs the edit. Fixes the Android OSR selection pipeline (render-frame metadata is now delivered before activation, since the after-activation callback never fires for a windowless view on Android) and wires the context-menu bridge in the OSR path. Validated on device. (FEATURE-066)
  • Passkey / WebAuthn via the Android Credential Manager. navigator.credentials.create/get({publicKey}) now reaches the Android Fido2 / Credential Manager, so providers such as Proton Pass are offered. (FEATURE-064)
  • Text-selection floating toolbar (windowed). Selecting text now shows the Android floating ActionMode (Select All / Copy / Paste / Share / Web Search / process-text), via CefriumActionModeCallback. (FEATURE-065)
  • Smart Text selection. The windowed selection toolbar now uses the platform TextClassifier, adding entity actions (phone -> call, address -> map, URL -> open), matching WebView. (FEATURE-065 follow-up)
  • OSR focused-node value + placeholder. CefriumRenderHandler.onFocusedNodeChanged(editable, value, placeholder, type) delivers the focused field's value, placeholder and type so an OSR consumer can mirror it in a native input overlay. (FEATURE-062)
0.9.1 CEF 7977 Chromium 152.0.7977.82 2026-09-22 superseded
Added
  • OSR IME + virtual keyboard (issue #9). Off-screen (OSR) browsers now drive the Android soft keyboard: CefriumRenderHandler.onVirtualKeyboardRequested(int) fires when an editable node gains/loses focus (hide only for TEXT_INPUT_MODE_NONE). New IME input path on CefriumBrowser: imeSetComposition, imeCommitText, imeFinishComposingText, imeCancelComposition, plus sendKeyEvent for backspace/enter/arrows. Wire a custom InputConnection to these from the View hosting the OSR frames (see the OsrImeActivity sample). Windowed/Surface mode already uses Android's native IME.
  • Full CEF public-API parity. The previously-unwired CEF handlers and CefBrowserHost methods are now exposed to the Java SDK, so you get WebView/CEF parity in one release:
  • CefriumDisplayHandler -- favicon URLs, JS console messages, fractional loading progress, status text, camera/mic in-use change.
  • CefriumLoadHandler -- onLoadStart, onLoadError (net error code + failed URL).
  • CefriumRequestHandler -- open-URL-from-tab, hung-renderer (ANR) un/responsive, render-view-ready, document-available, client-certificate selection, and response-side redirect/response/load-complete inspection.
  • File chooser (CefriumDialogHandler) -- <input type=file> via ACTION_GET_CONTENT. Plus beforeunload ("Leave site?") and JS-dialog lifecycle.
  • New handlers: CefriumKeyboardHandler (intercept keys), CefriumFocusHandler, CefriumDragHandler, CefriumFrameHandler (frame lifecycle), CefriumCommandHandler, and CefriumAudioHandler (raw PCM tap -- opt-in via setAudioHandler; enabling it redirects page audio).
  • OSR: HTML <select> dropdowns now render off-screen (onPopupPaint/onPopupShow/onPopupSize), plus IME composition-rect, text-selection and scroll-offset callbacks.
  • CefBrowserHost: exitFullscreen(), startDownload(url), getNavigationEntries() (history with titles), downloadImage(url,...); plus LifeSpan DoClose and permission prompt-dismiss.
  • Opt-in response-body tap (setResponseTapEnabled -> onResponseData) and per-cookie access filter (setCookieFilterEnabled -> onCanSendCookie/onCanSaveCookie) -- zero cost unless enabled.
0.9.0 CEF 7977 Chromium 152.0.7977.82 2026-09-19 superseded
Added
  • Open content:// URLs (Android content-provider URIs) in a tab. A FileProvider URI -- e.g. a downloaded file, or a file shared into the app -- now loads and renders (text/HTML/PDF/image). Previously net::ERR_UNKNOWN_URL_SCHEME. (Also enables opening a download inside the browser.)
  • Load APK-bundled web content: file:///android_asset/... and file:///android_res/.... Ship an offline web app (HTML/CSS/JS) inside your APK and load it directly, matching Android WebView. Served from the host app's AssetManager/Resources; top-level navigation and subresources both work.
  • Compose: CefriumViewState download support. A downloads list (per-id, live), an onDownloadEvent hook (for notifications), an onBeforeDownload hook (choose where to save, e.g. a SAF picker), and cancelDownload/pauseDownload/resumeDownload(id).
  • CefriumBrowser.cancelDownload/pauseDownload/resumeDownload(id) -- control a download by id (e.g. from a notification action) without holding the item.
  • Controllable download API (CefriumDownloadHandler). The previous OnDownloadListener could only observe a download after it had already started -- an accidental tap on a download link could not be stopped except by killing the app. The new handler mirrors CEF's CefDownloadHandler:
Fixed
  • Minified (R8) consumer builds no longer crash at startup with AbstractMethodError: Consumer.accept(Object). R8 stripped accept(Object) from Chromium's WindowLayoutInfoListener lambda (implements androidx.window.extensions.core...Consumer). The SDK now ships a consumer keep rule for the SAM method and declares androidx.window.extensions.core:core as a provided (compile-only) POM dependency so the consumer's R8 can resolve the interface -- no consumer workaround needed. Validated with a minified release build.
  • Multiple downloads from one page no longer silently blocked (this is what made data: / blob: downloads appear "unavailable"). Chromium's DownloadRequestLimiter allows the first automatic download from a page and then, with no permission-prompt UI attached (CEF attaches none), silently blocked every later one -- and blocked ALL but the first download from an opaque-origin page (data:/blob: pages, or content shown via loadHtml / loadDataWithBaseURL). The limiter now defers to the embedder's CanDownload when there is no prompt UI, so every download reaches the download handler and the app decides. Root cause was NOT a data:/blob: scheme filter (none exists in Chromium's download path); single downloads of those schemes already worked. Validated on device: 3 sequential data: downloads now all complete (previously only the first did).
0.8.9 CEF 7977 Chromium 152.0.7977.82 2026-09-18 superseded
Fixed
  • No longer crashes in off-screen (OSR) mode during single-page-app navigation. On a same-document navigation (e.g. an SPA route change on a sign-in page), the browser process could crash (SIGSEGV, null deref) inside Chromium's back/forward navigation-transition screenshot code, which dereferenced the view's native Android view without checking it -- and an off-screen view has none (GetNativeView() is null in OSR). The interceptor now fails safely when there is no native view, matching the function's existing guards. (Codeberg browser issue: OSR SIGSEGV on accounts.google.com.)
0.8.8 CEF 7977 Chromium 152.0.7977.82 2026-09-18 superseded
Added
  • External / app URL schemes are handed off to Android. When a page links to a non-web scheme -- an app deep link (baiduboxapp://, weixin://, intent://, market://) or a well-known external protocol (tel:, mailto:, geo:, sms:) -- the browser now fires an Android Intent to open the target app instead of showing "This site can't be reached". Parsing and security hardening (intent:// sanitization, S.browser_fallback_url, user-gesture / redirect rules) come from Chromium's own components/external_intents, installed as a navigation throttle on the browser's WebContents. http/https still load in the browser; an unknown scheme with no installed app fails gracefully (no crash, no error page). The SDK declares the <queries> needed for Android 11+ package visibility so consumers need no manifest changes. (Codeberg browser issue: URL scheme #6.)
0.8.7 CEF 7977 Chromium 152.0.7977.82 2026-09-17 superseded
Fixed
  • No longer crashes when a page opens a file-download link. A top-level navigation that turns into a download re-issues its request with the same request_id, which collided with the still-tracked navigation request in the request-interception layer. The colliding entry was freed and then used (use-after-free), crashing the browser process (SIGSEGV in InterceptedRequest::Restart). The interceptor now drops the duplicate instead of restarting a freed request; the download proceeds normally. Custom URL schemes that hit the same path are covered by the same fix. (Codeberg browser issues: file-download crash and URL-scheme crash.)
0.8.6 CEF 7977 Chromium 152.0.7977.82 2026-09-16 superseded
Fixed
  • setDarkMode() now affects the page's prefers-color-scheme. On Android the chrome ThemeService is not wired up, so setDarkMode was silently a no-op; the browser now drives the web content's preferred color scheme directly. window.matchMedia('(prefers-color-scheme: dark)') reflects it and CSS dark media queries take effect, in both windowless (OSR) and SurfaceView browsers. (Codeberg issue #4.)
0.8.5 CEF 7977 Chromium 152.0.7977.82 2026-09-12 superseded
Fixed
  • Intermittent (~50%) startup crash on some devices. A re-entrant recursion in the PartitionAlloc lock-metrics subsampler (its first-use RNG seed allocates under a contended lock, whose acquisition timer re-enters the sampler before the seed completes) could overflow the stack at startup. Guarded against re-entrancy. No API changes.
0.8.4 CEF 7977 Chromium 152.0.7977.82 2026-09-12 superseded
Added
  • Touch automation API. CefriumBrowser (and the Compose CefriumNavigator) gain sendTap, sendTouchDown / sendTouchMove / sendTouchUp, and sendSwipe (browser-viewport pixels). In the SurfaceView browser these drive the full gesture pipeline -- a tap synthesizes a click, a swipe scrolls/flings; in windowless (OSR) mode they use the CEF touch path. See the InputAutomationActivity sample.
0.8.3 CEF 7977 Chromium 152.0.7977.82 2026-09-11 superseded
Fixed
  • Mouse API now works in windowed / SurfaceView (ContentViewRenderView) mode. In 0.8.2 the mouse API only reached the renderer in windowless (OSR) mode; on a createWithSurface browser the events were silently dropped. They are now forwarded through the Android render widget host, so sendMouseMove / sendLeftClick / sendRightClick / etc. work in both rendering modes.
0.8.2 CEF 7977 Chromium 152.0.7977.82 2026-09-11 superseded
Added
  • Mouse event API. CefriumBrowser (and the Compose CefriumNavigator) gain sendMouseMove / sendMouseLeave / sendMouseClick / sendLeftClick / sendRightClick / sendDoubleClick / sendMouseDown / sendMouseUp / sendMouseWheel, with button and modifier parameters, mirroring the desktop CEF mouse surface. Coordinates are browser-viewport pixels.
Fixed
  • Android OSR input delivery. Injected pointer events were dropped before reaching the renderer on the Android off-screen (windowless) path (no DelegatedFrameHost): they are now dispatched directly, the paint-holding input hold is released on frame delivery, and the native cursor handle is null-guarded.
0.8.1 CEF 7977 Chromium 152.0.7977.82 2026-09-09 superseded
Added
  • Published to Maven Central (com.cefrium:*), alongside the Codeberg mirror. mavenCentral() resolves the SDK, Compose wrapper, and Gradle plugin with no extra repository line; every version stays available permanently.
Changed
  • Engine: Chromium 152.0.7977.75 -> 152.0.7977.82 (same CEF branch 7977) -- same-branch security bump for CVE parity with Debian. No API changes.
  • CefriumBrowser's package-private getWebContents() / connectWebContentsInternal() now carry @RestrictTo(LIBRARY) -- reaching them from a consumer module now warns at compile time. Never public API; no functional change.
0.8.0 CEF 7977 Chromium 152.0.7977.75 2026-09-06 superseded
Added
  • Disable pinch-to-zoom from the SDK: CefriumBrowser.setPinchToZoomEnabled(boolean) (View API) and CefriumNavigator.setPinchToZoomEnabled(boolean) (Compose API). Enabled by default; when disabled it forces a non-user-scalable viewport and blocks the multi-touch pinch gesture for pages you do not control, and reverts cleanly when re-enabled. Validated on device.
Changed
  • Engine: Chromium 151.0.7922.137 -> 152.0.7977.75 (CEF branch 7922 -> 7977) for CVE parity with the Debian Chromium release.
  • Consumer build baseline raised to AGP 9.4, Gradle 9.7.1, JDK 25, compileSdk 37. Chromium 152 ships Java-25 (class-file 69) bytecode, so older toolchains can no longer read or dex the SDK. On AGP 9 use built-in Kotlin (drop org.jetbrains.kotlin.android) and legacy jniLibs packaging. See the Quick Start.
0.7.1 CEF 7922 Chromium 151.0.7922.137 2026-08-17 Maven
Fixed
  • WebSockets to a local/private address no longer stall (issue #1). Chromium 151 enabled Local Network Access checks for WebSockets by default; a page connecting to localhost / a LAN address gated the handshake on a permission decision Cefrium has no UI to resolve, so it stalled (reported as extreme WebSocket latency after the 0.6.x -> 0.7.0 bump). Cefrium now disables the LNA feature, matching Android WebView. Validated on device: before, the handshake never completed; after, it connects immediately (50 messages round-trip in ~100 ms). A WebSocket regression guard was added to the on-device release gate.
Changed
  • Engine: Chromium 151.0.7922.71 -> 151.0.7922.137 (same CEF branch 7922). A same-branch security roll-up for CVE parity with the Debian Chromium release. No API changes.
0.7.0 CEF 7922 Chromium 151.0.7922.71 2026-08-03 Maven
Changed
  • Engine: Chromium 150.0.7871.114 -> 151.0.7922.71 (CEF 7871 -> 7922). Tracks the Debian Chromium security release for CVE parity. The API surface is unchanged for SDK consumers; Cefrium.CHROMIUM_VERSION now reports 151.0.7922.71. Validated on device (full instrumented + sample smoke + close-leak gates green on the W90).
0.6.5 CEF 7871 Chromium 150.0.7871.114 2026-08-03 Maven
Added
  • CefriumBrowser.setMediaSessionActivity(PendingIntent) (and Compose CefriumNavigator.setMediaSessionActivity) lets a multi-tab host make the media notification / lock-screen control open the SPECIFIC tab that is playing, not just the app. Each browser's MediaSessionCompat carries a settable session activity (overriding the default launcher intent added in 0.6.4); passing null restores the default. Validated on device.
0.6.4 CEF 7871 Chromium 150.0.7871.114 2026-07-31 Maven
Fixed
  • Tapping the media notification / lock-screen control now opens the app (the tab playing the media) instead of another app. CefriumMediaSession now sets a contentIntent on the notification and setSessionActivity on the MediaSessionCompat (the host app's launcher intent). Without a tap target, Android routed the control's tap to another active media session's owner (e.g. Spotify) even though the notification showed the Cefrium tab.
0.6.3 CEF 7871 Chromium 150.0.7871.114 2026-07-21 superseded
Fixed
  • Media notification / lock-screen progress bar now advances. CefriumMediaSession now observes Chromium's mediaSessionPositionChanged and pushes the media duration (METADATA_KEY_DURATION) plus the playback position + speed into the MediaSessionCompat PlaybackState, so Android renders and ticks the seekbar. Previously only the play/pause button worked -- the position was PLAYBACK_POSITION_UNKNOWN and no duration was set, so the bar had no range and never moved. Validated on device.
0.6.2 CEF 7871 Chromium 150.0.7871.114 2026-07-13 Fixes CVE-2026-15107 +26 superseded
Changed
  • Engine updated to Chromium 150.0.7871.114 (from 150.0.7871.46), a same-branch security patch bump tracking Debian's 150.0.7871.114-1~deb13u1 upload for CVE parity. The 150.0.7871.114 stable roll-up fixes 27 vulnerabilities, including two CRITICAL use-after-free flaws -- CVE-2026-15112 (Ozone) and CVE-2026-15129 (Views) -- plus high-severity memory-safety fixes across V8, ANGLE, WebRTC, Codecs, Autofill, Payments, Input, DOM and Forms. All 142 CEF + Android-port patches re-apply cleanly on the new tree (same CEF branch 7871 -- no rebase or patch regeneration needed). CVEs: CVE-2026-15107, CVE-2026-15108, CVE-2026-15109, CVE-2026-15110, CVE-2026-15111, CVE-2026-15112, CVE-2026-15113, CVE-2026-15114, CVE-2026-15115, CVE-2026-15116, CVE-2026-15117, CVE-2026-15118, CVE-2026-15119, CVE-2026-15120, CVE-2026-15121, CVE-2026-15122, CVE-2026-15123, CVE-2026-15124, CVE-2026-15125, CVE-2026-15126, CVE-2026-15127, CVE-2026-15128, CVE-2026-15129, CVE-2026-15130, CVE-2026-15131, CVE-2026-15132, CVE-2026-15133.
Fixed
  • isPlayingAudio() now uses only the actual-playback signal, not the is_suspended flag (which flickers mid-playback for media documents and made the getter spuriously read false for an audible tab). Now !mPlayingIds.isEmpty().
0.6.0 CEF 7871 Chromium 150.0.7871.46 2026-07-05 Fixes CVE-2026-13789 superseded
Changed
  • Engine updated to Chromium 150.0.7871.46 (from 149.0.7827.102), tracking Debian's security upload for CVE parity (includes the CVE-2026-13789 V8 fix and the rest of the 150 security roll-up). The Android port was rebased onto CEF branch 7871 and adapted to the Chromium 150 API: permission-prompt embedder seam regenerated, Android autofill client HideAutofillSuggestions -> HideSuggestions, RenderWidgetHostView::Show() -> ShowWithVisibility(), non-final R via app_as_shared_lib, and the payments Java service_impl_java dep. No SDK API changes for consumers -- a drop-in engine/security refresh.
0.5.9 CEF 7827 Chromium 149.0.7827.102 2026-07-03 superseded
Fixed
  • FedCM crash on federated sign-in pages. The Gradle plugin now generates the R class for org.chromium.chrome.browser.ui.android.webid; without it, a page that invoked the FedCM account chooser (AccountSelectionBridge.getBrandIconIdealSize) threw NoClassDefFoundError webid/R$dimen and crashed the browser process. Only reproduced on CERTIFIED devices (where FedCM runs). Validated on Redmi/HyperOS.
Added
  • Incognito (private) browsing. CefriumBrowser.createWithSurface(activity, incognito) + isIncognito(); Compose CefriumViewState(incognito = true) / rememberCefriumViewState(url, incognito). Incognito browsers share one off-the-record request context (isolated from normal tabs, in-memory) that is cleared when the last incognito browser closes. Validated on device: cookie isolation normal<->incognito and clear-on-close.
0.5.8 CEF 7827 Chromium 149.0.7827.102 2026-07-03 superseded
Fixed
  • Tab/session restore now loads the page instead of showing a blank tab (or crashing on some devices). CefriumViewState(navigationState = ...) restore deferred its load to the wrong moment: Restore() ran while the initial about:blank navigation was still pending (so nothing loaded -> blank), and forcing the load in OnAfterCreated navigated before the on-screen surface + overscroll handler existed, crashing the overscroll controller on the RenderFrameHost swap. Now restoreNavigationState rebuilds the stack without loading and schedules the surface connect (which restored tabs previously never did -- only loadUrl did); the load is triggered once, from connectWebContentsInternal, after the surface and handler are set up. Validated on a Redmi/W90 (Android 16, arm64) and rooted API-33/36 emulators, single- and multi-tab.
0.5.7 CEF 7827 Chromium 149.0.7827.102 2026-07-03 superseded
Notes
  • Native pull-to-refresh: an overscroll-down gesture at the top of a page reloads it. Opt-in via CefriumBrowser.setPullToRefreshEnabled(true) (CefriumNavigator.setPullToRefreshEnabled in Compose); the handler binds once when the WebContents connects.
0.5.6 CEF 7827 Chromium 149.0.7827.102 2026-07-02 superseded
Added
  • Tab back/forward history restore. CefriumBrowser.serializeNavigationState() / restoreNavigationState(byte[]) capture and rebuild a tab's full navigation stack (each entry's URL and page state), and CefriumViewState(navigationState = ...) restores it. A tab restored after the app is killed can navigate back through its history, not just show its current page.
0.5.5 CEF 7827 Chromium 149.0.7827.102 2026-07-02 superseded
Fixed
  • Background audio now keeps playing reliably when the app is minimized or the screen is off. The media foreground service is driven by actual WebContents playback instead of the media session's controllability signal (which could flicker), so the process stays alive while audio plays rather than being reclaimed after about a minute.
0.5.4 CEF 7827 Chromium 149.0.7827.102 2026-07-02 superseded
Highlights
  • New host API stopMediaSession() (on CefriumBrowser and the Compose CefriumNavigator): stops the page's media session and dismisses its media notification. It operates at the WebContents level, so it also reaches media inside cross-origin iframes (e.g. a YouTube embed) that page JavaScript cannot pause.
  • Hardware and Bluetooth media keys (play/pause) now control in-page media playback.
Fixed
  • The system media notification now appears reliably for media documents (navigating directly to an audio/video URL) and for pages that wire navigator.mediaSession after load. Previously it could fail to appear depending on when the media session was created.
0.5.3 CEF 7827 Chromium 149.0.7827.102 2026-06-24 superseded
Highlights
  • Web NFC (NDEFReader read/write) works end-to-end -- validated with a physical NDEF tag (read + write round-trip).
  • Renderer-termination callback: get told when a renderer process for your browser dies (e.g. the OEM low-memory killer reclaims it) so you can show a reload affordance instead of a silent blank page.
Added
  • CefriumBrowser.setOnRenderProcessTerminatedListener((status, errorCode) -> ...) with TERMINATION_* status constants. Compose: observe the hoisted CefriumViewState.rendererTermination or pass onRenderProcessTerminated to CefriumWebView.
  • CefriumBrowser.PERMISSION_NFC -- grant Web NFC via your setPermissionHandler or pre-authorize an origin with setContentSetting(url, PERMISSION_NFC, SETTING_ALLOW).
Fixed
  • Web NFC was previously wired but every scan/write was denied or hung. Three engine fixes: CEF mapped the NFC permission to an ungrantable type (added CEF_PERMISSION_TYPE_NFC); NfcBlocklist read a variations field-trial param whose JNI is absent in CEF and threw (guarded); and the consumer also needs android.permission.VIBRATE.
  • Renderer terminations Android reports as OOM_PROTECTED / EVICTED_FOR_MEMORY (the common OEM low-memory-kill path) now reach OnRenderProcessTerminated as TS_PROCESS_OOM -- the callback previously never fired for the most common Android renderer death.
  • Surface-mode crash on close: a deferred WebContents-connect callback could fire after the browser was torn down and dereference a stale pointer (SIGSEGV). It now short-circuits once the browser is closed.
Notes
  • Web NFC consumers must declare android.permission.NFC and android.permission.VIBRATE in their manifest.
  • Do NOT declare your own SandboxedProcessService entries -- the AAR provides them (40 isolated slots); a consumer-side count both fails the manifest merge and caps the pool. See the Memory & process model guide.
Validated
  • Redmi Note 13 Pro 5G / HyperOS: Web NFC read + write round-trip on a physical tag; renderer-termination on a real OEM low-memory kill.
  • W90: instrumented suite 41/41 on device before publish.
0.5.2 CEF 7827 Chromium 149.0.7827.102 2026-06-16 superseded
Highlights
  • Renderer lifetime & memory: showing many pages over time -- e.g. a CefriumBrowserPool of pages, each with a cross-origin iframe -- no longer leaks renderers or crashes on process-per-browser devices (HyperOS / Android 16).
Fixed
  • Closing/evicting a browser now completes Chromium's window-destruction handshake on Android (CloseHostWindow -> WindowDestroyed), so the WebContents and every subframe renderer (host page + cross-origin iframe) are actually destroyed.
  • 40 sandboxed render-process slots (was 5); the visible browser is marked IMPORTANT and detached pooled ones MODERATE, so the OS reclaims idle renderers first and never the active one.
  • Accessibility: apps with an accessibility service active (TalkBack, Switch Access) no longer crash with NoClassDefFoundError SelectionCompat when the a11y tree queries a CEF WebContents.
Added
  • CefriumBrowser.setCookie(url, name, value, secure, httpOnly, sameSite) and the Compose CefriumNavigator parity overload -- explicit Secure / HttpOnly / SameSite (NONE / LAX / STRICT / UNSPECIFIED). The 3-arg setCookie is unchanged.
  • Diagnostics: closedBrowserCount(), activeRenderProcessCount(), totalRenderFrameHostCount(), zeroFrameRenderProcessCount(), liveBrowserCount().
Notes
  • Do NOT declare your own SandboxedProcessService entries -- the AAR provides them; a lower count caps the pool. See the Memory & process model guide.
  • Inline YouTube via loadHtmlWithBaseUrl loads the real player, but YouTube's server-side integrity check rejects locally-injected documents (Error 152, same as WebView's loadDataWithBaseURL). To embed YouTube inline, serve the embed HTML from a real HTTP(S)/localhost origin and use loadUrl().
Validated
  • Redmi Note 13 Pro 5G / HyperOS: 40 pages, maxAlive=3, inline cross-origin YouTube video -- bounded and crash-free.
0.5.1 CEF 7827 Chromium 149.0.7827.102 2026-06-14 superseded
Added
  • loadHtmlWithBaseUrl / loadDataWithBaseUrl on CefriumBrowser and the Compose CefriumNavigator -- load an HTML string with a real base-URL origin and referrer (like Android WebView's loadDataWithBaseURL), so string-loaded content can host embeds that validate their parent origin (no Error 153).
Fixed
  • Startup crash on Xiaomi MIUI / HyperOS (DeviceFormFactor resource-resolver guard).
  • Native-FCM FirebaseMessaging.getToken() -- declares androidx.datastore-preferences for the vendored Firebase token path.
  • The chrome PasswordManager no longer terminates the renderer on a loadDataWithBaseURL data: form (which had left the surface blank).
Packaging
  • Orphaned okio classes stripped from the AAR (consumer's Gradle provides the single copy) -- no checkDuplicateClasses collisions.
Validated
  • On device, both codecs and libre variants.
0.5.0 CEF 7827 Chromium 149.0.7827.102 2026-06-10 superseded
Highlights
  • Major web-platform expansion: WebAuthn / passkeys, Web Bluetooth / USB / Serial device choosers, Payment Request (Google Pay), Contact Picker, File System Access, file upload, WebOTP, Web Speech recognition, Web NFC, screen capture, generic sensors, WebRTC, OPFS, and more -- inherits essentially the full Chromium web platform.
Fixed
  • File-picker result routing.
  • Modal-dialog host.
  • Video Picture-in-Picture made crash-safe.
Validated
  • Exhaustively on device.
0.4.1 CEF 7827 Chromium 149.0.7827.102 2026-06-09 superseded
Security
  • Chromium security respin: fixes CVE-2026-11645 (out-of-bounds memory access in V8, exploited in the wild) plus the other CVEs in 149.0.7827.102.
  • User-Agent now reports the real engine version.
0.4.0 CEF 7827 Chromium 149.0.7827.53 2026-06-08 superseded
Engine
  • Chromium engine bump 148 -> 149 (149.0.7827.53, CEF branch 7827) for CVE parity with Debian Chromium. 20 Android patches; multi-ABI AAR (arm64 + x86_64).
Validated
  • On device: CefInitialize, multi-process renderer, OnPaint off-screen render.
0.3.2 CEF 7778 Chromium 148.0.7778.167 2026-06-08 superseded
Added

  • Native FCM push (bring-your-own Firebase).
  • Per-origin permission via setContentSetting (View + Compose).
0.3.1 CEF 7778 Chromium 148.0.7778.167 2026-06-06 superseded
Added
  • Maven-consumable fat AAR (self-contained resources + manifest).
  • Zero-config init (no Application boilerplate).
  • SSL cert-error and HTTP-auth handlers (WebView parity).
0.3.0 CEF 7778 Chromium 148.0.7778.167 2026-06-05 superseded
Added
  • Web permissions, getUserMedia, system media controls, print-to-PDF, cookie and dynamic-settings APIs.
0.2.1 CEF 7778 Chromium 148.0.7778.167 2026-06-04 superseded
Packaging
  • First multi-ABI artifact (arm64-v8a + x86_64 in one AAR).
0.2.0 CEF 7778 Chromium 148.0.7778.167 2026-06-04 superseded
Packaging
  • Per-architecture artifacts; superseded the same day by 0.2.1 (multi-ABI).
0.1.0 CEF 7778 Chromium 148.0.7778.167 2026-05-26 superseded
Milestone
  • Early validation release.

Each release above is a source tag with notes -- the permanent parity and security record. The consumable .aar artifacts that Gradle resolves are published separately to the Codeberg Maven registry. See the Quickstart for the repository and coordinates, e.g. com.cefrium:cefrium-sdk:0.5.2. This list is the history and never loses an entry, even after an artifact is pruned.

Artifact retention

Pinning a version? Resolve from Maven Central (mavenCentral(), com.cefrium:*), where every published version stays available permanently. Central has carried the SDK since 0.8.1.

The Codeberg Maven mirror serves only the latest version during early validation, to respect Codeberg's donation-funded storage, so a coordinate pinned there stops resolving at the next release. Superseded versions are not retained as binaries on the mirror; each is reproducible from its source tag (see the build process in BUILD-GUIDE), and every release carries a SHA256SUMS of the artifacts as published for verification. This mirror policy will be revisited before 1.0 / first production adopters.

The SHA256SUMS file is GPG-signed (SHA256SUMS.asc, detached) with the maintainer's key, fingerprint 2A84 0ED0 0DE6 69F4 219B 8B33 02A7 9E3B 8215 1695. To verify a download:

gpg --recv-keys 02A79E3B82151695        # once, to fetch the public key
gpg --verify SHA256SUMS.asc SHA256SUMS  # checks the signature
sha256sum -c SHA256SUMS                 # checks the artifacts against it

These channels are what makes a build official. For how official builds and third-party derivatives are distinguished — and what the LGPL and the Cefrium trademark each cover — see Trademark & Forks.

Versioning: a release that adds public API is a minor bump; a fixes-only release is a patch; CEF/Chromium engine bumps are recorded regardless. See VERSIONING-CEFRIUM.md.
