Anki 26.05 release notes

What's Changed

New Installer

This release replaces the terminal-based launcher introduced in 25.07 with a more standard installation process:

Anki no longer shows a terminal on installation/update.
Installation no longer requires network access.
Updates can be installed using Tools>Check For Updates.
A standard MSI installer is provided for Windows.
A Windows ARM64 build is available.
The macOS builds require macOS 13 or later.
The Linux x86_64 build requires glibc 2.35+.
The Linux aarch64 build requires glibc 2.39+.
The minimum supported Python version is now 3.10 (The official builds still ship Python 3.13).
Qt has been updated to 6.11

Note: The Tools>Upgrade/Downgrade option in 25.07+ cannot be used to upgrade to this version due to packaging changes.
