tags: [“status update”]

Like last month, I am writing to you from the past, preparing this status update a day earlier than usual. This time it’s because I expect to be busy with planned sr.ht maintenance tomorrow, so I’m getting the status updates written ahead of time.

aerc has seen lots of patches merged recently thanks to the hard work of co-maintainer Reto Brunner and the many contributors who sent patches, ranging from a scrollable folder list to improvements and bugfixes for PGP support. We wrapped all of this up in the aerc 0.4.0 release in late May. Thanks to Reto and all of the other contributors for their hard work on aerc!

Wayland improvements have also continued at a good pace. I’ve mentioned before that wlroots is a crucial core component tying together a lot of different parts of the ecosystem — DRM/KMS, GBM, OpenGL, libinput, udev, and more — bringing together integrations for many disparate systems and providing a single unified multiplexer for them over the Wayland protocol. Taking full advantage of all of these systems and becoming a more perfect integration of them is a long-term goal, and we’ve been continuing to make headway on these goals over the past few weeks. We are working hard to squeeze every drop of performance out of your system.

In the SourceHut world, I’ve been working mainly on GraphQL support, as well as Alpine 3.12 upgrades (the latter being the source of the planned outage). I wrote in some detail on the sourcehut.org blog about why and how the GraphQL backends are being implemented, if you’re curious. The main development improvements in this respect which have occured since the last status updates are the introduction of a JavaScript-free GraphQL playground, and a GraphQL API for meta.sr.ht. Coming improvements will include an overhaul to authentication and OAuth2 support, and a dramatically improved approach to webhooks. Stay tuned!

That’s all for the time being. Thank you for your support and attention, and stay safe out there. I’ll see you next month!
