Hi!

Last week wlroots 0.19.0-rc1 has been released! It includes the new color management protocol, however it doesn’t include HDR10 support because the renderer and backend bits haven’t yet been merged. Also worth noting is full explicit synchronization support as well as the new screen capture protocols. I plan to release new release candidates weekly until we’re happy with the stability. Please test!

Sway is also getting close to its first release candidate. I plan to publish version 1.11.0-rc1 this week-end. Thanks to Ferdinand Bachmann, Sway no longer aborts on shutdown due to dangling signal listeners. I’ve also updated my HDR10 patch to add an output hdr command (but it’s Sway 1.12 material).

I’ve spent a bit of time on libicc, my C library to manipulate ICC profiles. I’ve introduced an encoder to make it easy to write new ICC profiles, and used that to write a small program to create an ICC profile which inverts colors. The encoder doesn’t support as many ICC elements as the decoder yet (patches welcome!), but does support many interesting bits for display profiles: basic matrices and curves, lut16Type elements and more advanced lutAToBType elements. New APIs have been introduced to apply ICC profile transforms to a color value. I’ve also added tests which compare the results given by libicc and by LittleCMS. For some reason lut16Type and lutAToBType results are multiplied by 2 by LittleCMS, I haven’t yet understood why that is, even after reading the spec in depth and staring at LittleCMS source code for a few hours (if you have a guess please ping me). In the future I’d like to add a small tool to convert ICC profiles to and from JSON files to make it easy to create new files or adjust exist ones.

Version 0.9.0 of the soju IRC bouncer has been released. Among the most notable changes, the database is used by default to store messages, pinned/muted channels and buffers can be synchronized across devices, and database queries have been optimized. I’ve continued working on the Goguma mobile IRC client, fixing a few bugs such as dangling Firebase push subscriptions and message notifications being dismissed too eagerly.

Max Ehrlich has contributed a mako patch to introduce a Notifications property to the mako-specific D-Bus API, so that external programs can monitor active notifications (e.g. display a count in a status bar, or display a list on a lockscreen).

That’s all I have in store, see you next month!
