• b8cd367 feat: add suppress_false_upgrade_notification by @Bush2021

  Portable Chrome has no updater, so it can show a false "Chrome is out of date" notice that you can't act on, most visibly on the Safety Check page in Settings.

  Set suppress_false_upgrade_notification to 1 to hide it (off by default). It only clears this false notice and won't hide a genuine update prompt.

  Check the new chrome++.ini for more detail.

Fix

• 6a1b366 fix: anchor bookmark new-tab click to the validated point by @Bush2021

  Fixes open_bookmark_new_tab opening the wrong entry in a vertical bookmark menu when the cursor kept moving after release: the new tab now opens the bookmark that was actually under the cursor.

  Fixes lag during left-clicking when open_bookmark_new_tab=1.

• 19db502 fix: patch resources.pak in the renderer process by @Bush2021

• 8b22f8d feat: migrate IA2 to UIA and support vertical tabs by @Bush2021

  This replaces the old IA2-based logic with a UIA-based implementation. Besides adding vertical tab support, it also fixes many long-standing tab interaction issues, improves behavior when the find/search bar changes the accessibility tree, and removes several fragile IA2-era hacks and workarounds.

  --force-renderer-accessibility is no longer needed. If you need custom new-tab matching, simply use new_tab_disable_name.

  This should also improve repeated close handling for tabs. Rapid double-click, middle-click, or right-click close gestures should no longer accidentally act on a tab that has already been destroyed, close extra tabs unintentionally, or trigger the vertical tabs crash described in #220.
