###### 1

* **🚨 Important: Fixed 10 taskbar and 10 Start menu crashing on 26xxx.8474+ and 28xxx.2298+.**
  * Due to 10 Start menu's tile layout engine being removed from `StartTileData.dll`, the 10 Start menu option has been temporarily hidden. (bf36cde, 8a5b8ba)
  * *The 10 Start menu option has been made available again in version 70.2.*
* **Highlight:** Fixed Windows 10 battery flyout crashing on 25951+. (659c2d0)
  * As a side effect, the network flyout buttons had to be reverted to pre-24H2. Fixes #4691.
* Changes to "Primary taskbar location on screen" in EP properties now reflect immediately. (6c9b41d)
* Windows 11 taskbar autohide is no longer modified on Explorer boot. (e6becc9)
* "Open Start in All apps by default" is now hidden when the new 11 Start menu is enabled. (#4648) (d8f1d1c)
* Windows 10 Start menu on 21996-22000.51 now no longer crashes. (39ac219)
* Fixed regedit.exe crashing when switching to thumbnail view in the import/export registry file dialog. (#3940) (80be85d)
* Updated pattern matching code to support recent builds especially with 26H1 ARM64. (677fd9f, e641e0a, e77123a, 3c8e79f, 854770b, 04dd52b, ce22476, baf0fdb, b532116, c0adee2, eefa0bf, 420e112, 3be4f3f, 1bf0d81, 47d7481, 31d2c23, bdf95c3, fe8cc2b, 1be3c79)
  * Improved efficiency on ARM64.
* Added Greek translations. Thanks @KonVetsos!

**ep_taskbar:**
* Now supports all 43 Windows 11 languages.
* Fixed reimplementation mistakes in system tray and some other places.
* [For mod developers] Changed ep_taskbar's DLL names from numbers to the codename of the first major release a single variant supports. (cc36e34)
* [For mod developers] TrayUI no longer inherits `Microsoft::WRL::RuntimeClass`; vtables are now stable on builds with multiple `ITrayUI` revisions like `ep_taskbar.ge.dll` (formerly `ep_taskbar.5.dll`).

###### 2

* Introduced a reimplemented 10 Start menu tile layout engine that was removed in 26xxx.8474. (688514f)
  * *A full restoration has been introduced in version 70.4*.
* Added an executable name blacklist to prevent shell extension from loading in certain applications. (#4819) (991b8ca)
* Updated 10 Start menu animation patterns for 28xxx.2149+ ARM64. (c480fc2)

**ep_taskbar:**
* Fixed a deadlock relating to base EP reporting taskbar position and the taskbar reporting search/task view button location and size both to `WindowsUdk.ShellCommon.dll` during taskbar initialization.
