Attention PDS devs! We merged a lexicon change last week increasing the max image upload for Bluesky posts from 1 MB to 2 MB. This rolled out to our PDSs instances last Friday. We'll begin enabling this in the Bluesky app soon. If your PDS implementation is still validating at 1 MB, plz update! ✌️

Related to this, we've been slowly rolling out a higher resolution limit for our image uploads, from 2000px^2 to 4000px^2. Until the below image size increase rolls out (soon), image sizes are still capped at 1 MB, so FYI you won't see immediate quality increase in all cases just yet.

github.comIt's really cool that people are now using Bluesky not only from servers they host themselves, but servers they *wrote* themselves (or someone else here did), adding features the standard one doesn't have ❤️ Like, I now have 2FA again on my PDS because @baileytownsend.dev just went and built it

Cirrus PDS now support passkey auth. It was a bit of a puzzle adding it to a tool where where the admin is all CLI, but I'm really pleased with the flow I came up with. Give it a go! github.com/ascorbic/cirrus If you don't know what Cirrus is, it's a really easy way to host your own Bluesky data
It's 100mb now in the reference PDS installer: github.com/bluesky-social/pds/blob/main/… Though each PDS may be configured with different limits, and I'm not sure if the actual limit is advertised anywhere.
Making good progress on hosting an AT Proto PDS for new micro.blog users. It’ll launch soon. Important note: it is not for people who already use Bluesky, at least not yet. The goal is to give new users an account on the atmosphere. Existing users will be happier sticking with the Bluesky PDS.
Am I missing something or is the Bluesky new-PDS daily relay limit for an _entire PDS_ lower than the limits they give to a _one single repo_ on their hosted PDSses? docs.bsky.app/docs/advanced-guides/rate-lim…
