+## Class: NavigationHistory
+
+> Manage a list of navigation entries, representing the user's browsing history within the application.
+
+Process: [Main](../glossary.md#main-process)<br />
+_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
+
+Each navigation entry corresponds to a specific page. The indexing system follows a sequential order, where the first available navigation entry is at index 0, representing the earliest visited page, and the latest navigation entry is at index N, representing the most recent page. Maintaining this ordered list of navigation entries enables seamless navigation both backward and forward through the user's browsing history.
+
+### Instance Methods
+
+#### `navigationHistory.getActiveIndex()`
+
+Returns `Integer` - The index of the current page, from which we would go back/forward or reload.
+
+#### `navigationHistory.getEntryAtIndex(index)`
+
+* `index` Integer
+
+Returns `Object`:
+
+* `url` string - The URL of the navigation entry at the given index.
+* `title` string - The page title of the navigation entry at the given index.
+
+If index is out of bounds (greater than history length or less than 0), null will be returned.
+
+#### `navigationHistory.length()`

+Returns `Integer` - History length.

+Given a switch with a constant condition and all cases the same
+(branching to the same successor), dxil-remove-dead-blocks would
+incorrectly remove the switch when replacing it with a branch, by
+forgetting to remove the N-1 incoming values to the PHIs in the
+successor block.

+Subject: Fix invalid IR from scalarrepl-param-hlsl in ReplaceConstantWithInst
+ (#6556)
+
+ReplaceConstantWithInst(C, V) replaces uses of C in the current function
+with V. If such a use C is an instruction I, the it replaces uses of C
+in I with V. However, this function did not make sure to only perform
+this replacement if V dominates I. As a result, it may end up replacing
+uses of C in instructions before the definition of V.
+
+The fix is to lazily compute the dominator tree in
+ReplaceConstantWithInst so that we can guard the replacement with that
+dominance check.
+

+Subject: Loop exit restructurizer: don't iterate over uses while mutating them
+ (#6644)
+
+The SkipBlockWithBranch function does the following:
+- Splits the block into three blocks with an if-then-endif structure.
+- Moves most instructions from the original block into the "then" block
+- If any of those values are used outside the original block, they are
+propagated through newly-constructed phis in the 'endif' block.
+
+This algorithm had a bug where the uses of a value were being scanned
+while the uses were also being updated. In some cases a downstream
+out-of-block use could be skipped. That results in an invalid module
+because now the original definition is now in the 'then' block, which
+does not dominate the downstream out-of-block use.
+
+Add a test that demonstrates the problem.
+

+Subject: Fix use-after-free in SimplifyCFG (#6628)
+
+When SimplifySwitchOnSelect calls SimplifyTerminatorOnSelect, it holds
+onto the select's condition value to use for the conditional branch it
+replaces the switch with. When removing the switch's unused
+predecessors, it must make sure not to delete PHIs in case one of them
+is used by the condition value, otherwise the condition value itself may
+get deleted, resulting in an use-after-free.
+
+Note that this was fixed in LLVM as well:

+Subject: indvars: don't replace a phi when that breaks LCSSA (#6695)
+
+Induction variable simplification (indvars) tries to rewrite exit
+values; these appear as phi nodes in loop exit blocks. If the
+replacement for the phi is still in the loop, then that would break the
+LCSSA property. Don't do that.
+
+Add a test for this.

+Subject: Fix invalid module bitcode when indexing a swizzled bool vector
+ (#6582)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When indexing a swizzled bool vector, some HLSL-specific code in
+EmitCXXMemberOrOperatorMemberCallExpr kicks in to handle the
+HLSLVecType. In this case, we’re dealing with an ExtVectorElt because of
+the swizzle, so this function creates a GEP, Load, and Store on the
+vector. However, boolean scalars are returned as type i11 while the
+store is storing to a bool, which is an i32, so we need to insert a cast
+before the store.

+Subject: Fix crash in scalarrepl-param-hlsl when dynamically indexing a GEP of
+ a constant indexed GEP (#6670)
+
+When processing global values to determine when to flatten vectors, this
+pass was only checking the immdiate users of the value for non-dynamic
+indexing of the vector. But this would fail in the case of a dynamic
+indexed GEP of a constant indexed GEP (e.g. h[0][a]) because the first
+level GEP was constant indexed, but not the second. We fix this by
+checking the full User tree of the value in `hasDynamicVectorIndexing`.

+Subject: Fix another UAF in SimplifyCFG (#6680)
+
+In certain cases of unreachable code, SimplifyCFG could try to replace a
+phi node with a select where the phi node itself was the select's
+condition. This resulted in an ASAN use-after-free during SimplifyCFG.
+
+The test case added isn't quite ideal because by the end of the
+SimplifyCFG pass, the phi node is restored to its original state both
+before and after this fix. However, an ASAN build of `dxopt` or
+`check-clang-dxc` will identify a heap-use-after-free failure in the
+intermediary steps of this test without this patch and succeeds with it.
+
+This was also fixed in upstream LLVM:
+https://github.com/llvm/llvm-project/commit/602ab248335e1540e82667e74fea44b7f042e112

+Subject: Add CMake option DXC_CODEGEN_EXCEPTIONS_TRAP (#6764)
+
+When enabled, any hlsl::Exception thrown during code generation and
+optimization will cause the process to trap.
+
+Bug: 346618785
+Change-Id: I9ac966d339ec3090e3455d51a9d7516cc5a3f153
+
+HLMatrixLower: allow exceptions to propagate out (#6710)
+
+If an exception is thrown, don't block it in the TempOverloadPool
+destructor. Allow it to propagate out as a user-visible error.
+
+Explicitly clear the TempOverloadPool before returning from the
+HLMatrixLowerPass::runOnModule. In the normal case, when no exception is
+thrown, that will still verify that all the overloads actually have been
+lowered, and will assert out if they aren't.

+Subject: Fix instcombine overflow check inserting inst at wrong place (#6679)
+
+When optimizing an overflow check of an add followed by a compare, the
+new instruction was being inserted at the compare, and the add removed.
+This produced invalid IR in cases where there were other uses of the
+former add between it and the compare. This fix makes sure to insert the
+new instruction at the old add location, rather than at the compare.
+
+Note that this was also fixed in LLVM:

+Subject: Fix LoopDeletion incorrectly updating PHI with multiple duplicate
+ inputs (#6643)
+
+LoopDeletion was incorrectly updating PHI nodes in the target block when
+it had duplicate input edges. This happens, for example, when deleting a
+loop that uses a switch with multiple cases that exit the same way.
+
+After determining that this was the bug, I found this fix in LLVM:
+https://reviews.llvm.org/D34516 and applied it here.

+Subject: Replace dynamic_cast with virtual call (#6515)
+
+Make TextDiagnosticPrinter::setPrefix a virtual function in base class
+DiagnosticConsumer. This allows us to avoid using dynamic_cast in
+BackendConsumer::DxilDiagHandler, required for codebases that do not
+enable RTTI. This is also the only place in the codebase that uses RTTI
+(AFAICT).

+Subject: Fixed crash in loop unroll caused by bug in structurize loop exits
+ (#6548)
+
+Fixed a bug in `hlsl::RemoveUnstructuredLoopExits` where when a new
+exiting block is created from splitting, it was added to the current
+loop being processed, when it could also part of an inner loop. Not
+adding the new block to inner loops that it's part of makes the inner
+loops malformed, and causes crash.
+
+This fix adds the new block to the inner most loop that it should be
+part of. Also adds the `StructurizeLoopExits` option to `loop-unroll`
+pass, which was missing before.

+Subject: M124: Vulkan: Turn SPIR-V limitations to crash instead of security
+ bug
+
+The input shader can be made complex in a number of different ways,
+resulting in instructions with a length higher than what can fit in
+SPIR-V (i.e. 16 bits).  Ideally, the translator would catch such complex
+usage early on and gracefully fail compilation.  However, as a safety
+net, this change makes sure such a case is detected when the SPIR-V
+instruction is being generated and turned into a crash.  This makes sure
+such bugs are no longer security bugs.

+Subject: M123: Vulkan: Fix access to inactive attributes

+... within range of active ones.  Since a buffer is bound for inactive
+attributes, it must be considered accessed.
+
+Ultimately, the nullDescriptor feature could be used to avoid binding a
+buffer for inactive attributes.

+Subject: Avoid clearing/resetting focus on an already focus event
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When we set the focus via an accessibility API on an element that
+is already focused, we first remove the focus and reset it. This
+leads to blur/focusout/focusin events being fired again.
+
+This behavior is different than the one we get when we set focus
+programmatically, with a mouse, or a keyboard, on an already
+focused element. In order to keep the same experience across all
+input modalities, this CL removes the divergent focus behavior
+for accessibility APIs.
+
+We tried to remove this code two years ago (CL:3547796) but it
+got reverted due to bug:40850837. This time, I made sure to discuss
+this issue with the Chrome Android accessibility owners to make 
+sure it's safe to remove. They landed CL:5345750, and then gave
+us the green light to land this CL.

+Subject: Fix size calculations in V8StringToUTF8
+
+While I'm here, remove the unnecessary use of base::WriteInto, which is
+a remnant of C++03 copy-on-write strings. Also ask V8 not to write a
+NUL terminator because std::(u16)string already owns that byte.

+Subject: Fix pointer tear down order problem
+
+Holding a RenderFrameHost* in the `OnceBinding` isn't safe,
+because the `RenderFrameHost` can be destroyed before the
+binding. This CL changes the task strategy so that the
+RenderFrameHost* doesn't need to be bound in a callback.
+
+Tested using the repro steps in the bug and this change stops
+it from reproducing.

+Subject: Prevent script injection on reload when racing with a navigation
+
+DevTools passes the loaderId now when calling Page.reload, in order to
+prevent accidentally reloading the wrong page when a navigation occurred
+concurrently. It can still happen that the navigation kicks in in between the reload iniated in the browser and the script injection that happens in the renderer, which would run the injected script on the wrong target. We need to check the loaderId also on the renderer side.

+Subject: Handle ThrottlingURLLoader deletion during throttle calls
+
+Theoretically `ThrottlingURLLoader` can be deleted during
+throttle calls and some call sites have already protection
+for such cases. This CL adds the protection for more call sites.
+
+This CL also adds more unit tests for cancelling/deleting
+`ThrottlingURLLoader` during throttle calls.

+Subject: feat: add support for missing dialog features to //shell_dialogs
+
+This CL adds support for the following features to //shell_dialogs:
+* buttonLabel - Custom label for the confirmation button.
+* showHiddenFiles - Show hidden files in dialog.
+* showOverwriteConfirmation - Whether the user will be presented a confirmation dialog if the user types a file name that already exists.
+
+This may be partially upstreamed to Chromium in the future.

+Subject: feat: enable passing exit code on service process crash
+
+This patch enables plumbing the exit code of the service process to the
+browser process when the service process crashes. The process can perform cleanup
+after the message pipe disconnection, which previously led to racy and incorrect
+exit codes in some crashing scenarios. To mitigate this, we can rely on
+ServiceProcessHost::Observer functions, but we need to pass the exit code to
+the observer.

+Subject: MediaSession: Use a MediaSessionImpl WeakPtr in
+ MediaSessionServiceImpl
+
+Currently, every time MediaSessionServiceImpl wants to talk to its
+associated MediaSessionImpl, it recalculates it from its
+RenderFrameHostId. This can lead to issues where a
+MediaSessionServiceImpl of a disconnected RenderFrameHost can no longer
+access the MediaSessionImpl to tell it that it is being deleted,
+leaving MediaSessionImpl with a dangling raw_ptr.

+Subject: Merge "Fix DOMArrayBuffer::IsDetached()" and "Comment out a CHECK
+ that a DOMAB has maximally one non-detached JSAB"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+1)
+
+A DOMArrayBuffer was maintaining its own "is_detached_" state, and
+would consider itself non-detached even if the corresponding
+JSArrayBuffer (or, all of them, in case there are several) was
+detached.
+
+Piping in the v8::Isolate would be a too big change for this fix, so this is using v8::Isolate::GetCurrent() for now.
+
+2)
+
+Comment out a CHECK that a DOMAB has maximally one non-detached JSAB
+
+Based on crash reports, this assumption is not true and has to be
+investigated.
+
+Removing this newly introduced CHECK to be able to merge fixes in this
+area - we still violate this invariant but the fixes are a step into
+the right direction.
+
+Fix in question:
+https://chromium-review.googlesource.com/5387887
+which also introduced this CHECK.

+Subject: Use localized display label only for browser process
+
+With https://crrev.com/c/5098130, GetPrimaryDisplayRefreshIntervalFromXrandr uses BuildDisplaysFromXRandRInfo
+to calculate the primary display frequency. In software compositing mode --disable-gpu-compositing,
+this code path will be called from the gpu process via SoftwareOutputSurface::SwapBuffers and
+can trigger a crash when attempting to set localized string. This is because on linux,
+gpu process does not have access to the resource bundle.
