release notes

[!IMPORTANT]
Linux packages have been migrated from GitHub Releases to distro-specific build services. For additional information see: Installing meshtasticd

⚠️ Known issues

We are cautiously optimistic that many of the intrinsic file system (LittleFS) issues on NRF52 based devices and instability should be resolved in this release. A full flash erase may be required if you are experiencing LFS assert issues.
Bluetooth was inadvertently disabled for T-Deck and T-Watch devices, preventing pairing with client apps. This issue will be resolved in the next alpha release after 2.5.21.
