Hello world,

we will be performing an update to Lemmy 0.19.11 in an hour.

We are planning for around 15 minutes of downtime today at 21:30-21:45 UTC.

You can convert this to your local time here: https://inmytime.zone/?iso=2025-05-03T21%3A30%3A00.000Z

As mentioned in our April update, we had already backported most of the Lemmy-UI changes for 0.19.11, but we were still missing most of the backend changes.

This update will bring us the remaining changes listed in the release notes, as well as some additional changes not yet released:

• user registrations are now processed in a DB transaction, which prevents some errors we've occasionally seen in the past where registrations rarely resulted in an inconsistent user creation state (#5480)
• new posts in NSFW communities are now always marked NSFW (#5310)
• another round of peertube federation fixes (#5652)
• fixed email notifications for denied applications (#5641)
  this was already supposed to be part of 0.19.11 but it did not work there. we are migrating our previous external email notification implementation to let Lemmy handle sending emails now.
• various fixes for opentelemetry that are not present in upstream Lemmy
  As Lemmy opentelemetry has been removed from Lemmy 1.0 this is not code that we are currently planning to upstream to the 0.19 branch, but we intend to keep using this going forward.

If you are an instance admin considering enabling opentelemetry in Lemmy 0.19, don't do that unless you also apply a similar set of patches to bring the related libraries to newer versions, as your instance will otherwise lock up after some requests.

Update 21:50 UTC: The update has been completed successfully and within the planned amount of time.
