As always, lots of improvements. The focus has been on performance improvements, especially on slow HW like Raspberry Pi 3B+. We achieved 240x speed improvements in several dashboards :rocket: And we welcomed @swiffer to the TeslaMate-Org team :wave: And much, much more. Enjoy it.

Regarding PostgreSQL 17: TeslaMate uses PostgreSQL as database, this is an external dependency and needs to be updated by yourself. Although TeslaMate currently runs fine with PostgreSQL 12+ we strongly recommend upgrading to the latest supported version. We recommend that you do this as follows:

• Backup your data
• Upgrade TeslaMate to this version
• Backup your data after the upgrade
• Upgrade PostgreSQL to postgres:17 (Yes, you will have to erase your data, which is why you need your backup in the first place.)

Additional info: In some very rare cases with very old installations of TeslaMate (from 2019) we have observed performance issues due to missing indexes. These should normally be added with our automatic migrations. If you think your installation may be missing some indexes, see #4201 for the corrective SQL command.
