+From: Anders Hartvoll Ruud <andruud@chromium.org>
+Date: Wed, 25 Feb 2026 03:24:31 -0800
+Subject: Stringify CSSUnparsedValues via toString, as normal
+
+CSSUnparsedValue exposes a special stringification function
+ToUnparsedString() in addition to the regular toString().
+The documentation says it returns "tokens without substituting
+variables", but it's not clear what this means; we don't substitute
+any variables in CSSStyleValue::toString() either.
+
+This CL makes ToUnparsedString() private (and renames it).
+Clients needing to serialize a CSSUnparsedValue can do so via
+the normal toString() function. (If ToUnparsedString() existed
+for performance reasons, that should have been documented.)
+
+Also, the /**/-"fixup" pass over the value has been folded into
+ToStringInternal(). This is to make it easy to find the canonical string
+representation of this value within CSSUnparsedValue (without going
+through a CSSValue).
+
+The main point of this CL is to prepare for validating
+the "argument grammar" of the value during the StyleValue-to-CSSValue
+conversion in StylePropertyMap (which requires item (2) above).
+
+We now jump through additional hoops to ultimately get a string
+from the outside of CSSUnparsedValue, but there should otherwise
+be no behavior change.

+Subject: [M146][base] Fix UAF in base::OnceCallbackList on re-entrant Notify()
+
+Before this patch, `base::OnceCallbackList` was susceptible to a
+heap-use-after-free when `Notify()` was called re-entrantly.
+
+The UAF occurred because `OnceCallbackList::RunCallback()` immediately
+spliced executed nodes out of `callbacks_` and into `null_callbacks_`.
+If a nested `Notify()` executed a node that an outer `Notify()` loop was
+already holding an iterator to, and that node's subscription was
+subsequently destroyed during the re-entrant cycle, the node would be
+physically erased from `null_callbacks_`. When control returned to the
+outer loop, it would attempt to evaluate the now-dangling iterator.
+
+This CL fixes the bug by deferring list mutations until the outermost
+iteration completes:
+1. `RunCallback()` no longer splices nodes during iteration.
+2. Cancellation logic is pushed down to the subclasses via a new
+   `CancelCallback()` hook, which is an extension to the pre-existing
+   `CancelNullCallback()` with increased responsibilities and clearer
+   semantics.
+3. If a subscription is destroyed while `is_iterating` is true,
+   `OnceCallbackList` resets the node and stashes its iterator in
+   `pending_erasures_`.
+4. A new `CleanUpNullCallbacksPostIteration()` phase runs at the end
+   of the outermost `Notify()`, which safely splices executed nodes
+   into `null_callbacks_` and physically erases the pending dead nodes.
+
+As a side effect, the type-trait hack in `Notify()` based on
+`is_instantiation<CallbackType, OnceCallback>` can be removed, because
+this information is exposed directly by
+`OnceCallbackList::CleanUpNullCallbacksPostIteration()`.
+
+The newly-added unit-test
+CallbackListTest.OnceCallbackListCancelDuringReentrantNotify reproduces
+the scenario and crashed before this patch.
+

+From: Anders Hartvoll Ruud <andruud@chromium.org>
+Date: Wed, 25 Feb 2026 03:24:19 -0800
+Subject: Describe a vector of segments as "segments", not "tokens"
+
+The specification uses the term "tokens" to refer to a sequence
+of V8CSSUnparsedSegment objects, and CSSUnparsedValue has adopted
+this terminology. While it is usually a good idea for Blink
+to mirror the language used in specifications, "tokens" is very
+confusing here, since it always means CSSParserTokens in every other
+place in the style code.

+Subject: [M146] Increment WebGL context generation number on context restore
+
+Objects created while the context is lost should not be valid to use
+after the context is restored.
+- Replace number_of_context_losses_ with a "context generation number"
+  which increments on both context loss and context restore.
+  - Technically, it would make sense to increment it only on context
+    restore, but just in case any logic is relying on the current
+    behavior, increment it in both places.
+  - It's uint64_t just in case someone figures out how to increment it 4
+    billion times.
+- Remove unused WebGLRenderingContextBase::number_of_context_losses_,
+  left over from before it was moved into WebGLContextObjectSupport.
+

+Subject: Validate CSSUnparsedValues upon assignment
+
+CSS Typed OM has a concept of a value "matching a grammar" (or not)
+upon assignment to a property [1]. For CSSUnparsedValues, we currently
+don't perform any significant validation, and as a consequence
+we allow "invalid" CSSUnparsedDeclarationValues to be created
+(causing DCHECKs later in the pipeline).
+
+This CL makes sure values can be parsed using CSSVariableParser::
+ConsumeUnparsedDeclaration before assignment.
+
+We're still not handling the value in the context of the destination
+property, which we probably should. This is also a problem with
+current state of things, however, so for now the goal is primarily
+to avoid the DCHECKs in Issue 484751092.
+
+Finally, I opened an issue against the specification [2], which
+currently doesn't define any of this.

+From: Geoff Lang <geofflang@chromium.org>
+Date: Wed, 18 Feb 2026 13:54:37 -0800
+Subject: Validate uniform block count limits at compile time on IMG.
+
+Normally these limits are validated at link time but the IMG compiler
+has issues when these limits are exceeded. Validate at compile time
+instead.

+From: Keeley Hammond <khammond@slack-corp.com>
+Date: Thu, 19 Mar 2026 00:34:37 -0700
+Subject: fix: fire MENU_POPUP_START for dynamically created ARIA menus
+
+When an ARIA menu element is dynamically created (e.g. via appendChild)
+rather than being shown by toggling visibility, the AXMenuOpened event
+was not fired. The OnIgnoredChanged path handles the visibility toggle
+case, but OnAtomicUpdateFinished did not fire MENU_POPUP_START for
+newly created menu nodes.
+
+Previous attempts to fix this (crbug.com/1254875) were reverted because
+they fired the event too eagerly in OnNodeCreated (before the tree was
+fully formed) and without filtering, causing regressions with screen
+readers on pages that misused role="menu".
+
+This fix addresses both issues:
+1. Fires MENU_POPUP_START in OnAtomicUpdateFinished (after the tree
+   update is complete) rather than in OnNodeCreated.
+2. Only fires if the menu has at least one menuitem child, filtering
+   out false positives from misused role="menu" elements.
+
+MENU_POPUP_END for deleted menus is already handled by
+AXTreeManager::OnNodeWillBeDeleted, which fires the event directly
+on the menu node before destruction.
+
+The change is behind the DynamicMenuPopupEvents feature flag, disabled
+by default, to allow stabilization before enabling by default. Enable
+with --enable-features=DynamicMenuPopupEvents.
+
+This patch can be removed when a CL containing the fix is accepted
+into Chromium.

+Subject: Mac: Fix WebRTC window icon conversion via gfx::Image
+
+The current WebRTC window picker implementation tries to manually convert
+NSImages to ImageSkia, but it does this incorrectly. As a result, the
+icons can appear corrupted or blank.
+
+This CL resolves the issue by using gfx::Image for the conversion. This
+method offers a reliable and standard way to change an NSImage into an
+ImageSkia.
+
+Feature-Flag: kUseGfxImageForMacWindowIcons

+Subject: fix: prefer browser runtime over node in HostRuntime detection
+
+In Electron, the `process` global is available in renderer processes,
+including the DevTools renderer. This causes the IS_NODE check to pass,
+leading DevTools to attempt importing the Node.js platform runtime
+(which uses `node:worker_threads`). However, DevTools Web Workers
+running under the `devtools://` protocol don't have access to Node.js
+built-in modules, resulting in a failed dynamic import.
+
+Fix by checking IS_BROWSER first, since DevTools always runs in a
+browser-like environment. The Node.js runtime is only needed when
+DevTools runs under pure Node.js (e.g., CLI tooling or testing).

+Subject: fix: clean up orphaned staged updates before downloading new update
+
+When checkForUpdates() is called while an update is already staged,
+Squirrel creates a new temporary directory for the download without
+cleaning up the old one. This can lead to significant disk usage if
+the app keeps checking for updates without restarting.
+
+This change adds a pruneOrphanedUpdateDirectories step before creating
+a new temp directory. Unlike a blanket prune, this reads the current
+ShipItState.plist and preserves the directory it references, deleting
+only truly orphaned update directories. This keeps the on-disk
+footprint bounded (at most 2 dirs) while ensuring quitAndInstall
+remains safe to call even when a new check is in progress.

+Subject: [M144 Merge] [maglev] fix CanElideWriteBarrier Smi recording for phis
+
+Recording a Tagged use is not enough for 2 reasons:
+
+  * Tagged uses are sometimes ignored, in particular for loop phis
+    where we distinguish in-loop and out-of-loop uses.
+
+  * This Tagged use could only prevent untagging of this specific phi,
+    but none of its inputs. So we could have a Smi phi as input to the
+    current phi which gets untagged and retagged to a non-Smi, all
+    while the current phi doesn't get untagged.
