This is the first public release, so the changelog is short. Every later version will land there with what changed and anything you need to know before upgrading.

What your host needs

PHP 8.1 or newer Extensions pdo · mbstring · json · openssl · session Database pdo_sqlite (recommended) or pdo_mysql Hosting any writable web directory · cron optional, never required

If you are not sure whether your host qualifies, upload the folder and open install.php. The first screen checks everything above and tells you plainly what is missing, if anything. Nothing is written until you get past it.

Installing

The installer prints a cron line at the end. Adding it is optional: with no cron entry at all the board runs its own housekeeping on caller traffic instead. The full walkthrough is chapter 2 of the manual.

Upgrading from an earlier version

Backing it up

Everything that is yours lives in data/: the configuration, the database, your themes, your door storage. Copy that one folder and you have the whole board. Copy it back and it is running again. On MySQL, dump the database too.

What you can do with it
