river 0.3.0

NOTICE: This is the last river release that will be announced on github. The upstream river repository has moved to https://codeberg.org/river/river and this release as well as all past and future releases can be found there.

This one's been in the pipeline for quite a while, it's been over a year since 0.2.0 was released and river has seen significant improvements since then. The past few months I've done my best to fix as many bugs as possible but a non-bugfix release always entails new code reaching a lot of people with diverse setups. If you find a bug in river please open an issue.

Here's a summary of the important changes since river 0.2.

New features:

• Better rendering performance due to the new wlroots rendering API and gles2 renderer improvements.
• Finely-grained damage tracking leveraging the wlroots scene graph API.
• Interactive resize of windows with the cursor from all edges/corners.
• Basic tablet input support
  • Only the tablet-v2 protocol is is supported, no pointer emulation is done.
  • Drawing with a tablet tool works in inkscape, libreoffice, etc.
  • Tablet pad input devices are not yet supported, tracking issue: https://codeberg.org/river/river/issues/1021
• Rules system to apply settings to windows with a matching app-id/title. See rule-add in the riverctl(1) man page. The following rule types are added in this release:
  • float/no-float
  • ssd/csd
  • fullscreen/no-fullscreen
  • tags
  • output
  • position
  • dimensions
• New -current-tags flag for send-to-output
• New -no-xwayland flag for starting river with xwayland disabled even if built with support.
• New above, below and after <N> attach modes plus the ability to configure attach mode per output with the new output-attach-mode riverctl command.
• New -skip-floating flag for focus-view
• New scroll-factor input configuration option
• The input-method-v2 and text-input-v3 protocols are supported, with the exception of input-method popups.
• The presentation-time protocol is supported.
• The fractional-scale-v1 protocol is supported.
• The cursor-shape-v1 protocol is supported.
• The xdg-shell protocol version 5 is supported, up from version 2.

Breaking changes compared to 0.2:

• River now honors the client-side vs server-side decoration wishes of clients by default instead of attempting to force server-side decorations everywhere. To approximate the old behavior the command riverctl rule-add ssd may be used.
• The float-filter-add and csd-filter-add riverctl commands have been removed, use rule-add instead and see the riverctl(1) man page for documentation.
• The attach-mode riverctl command is deprecated and currently aliased to the new default-attach-mode command. The alias may be removed in the future.
• Rendering order has changed slightly and and is now based off of focus order instead of window management stack order.
• Pointer constraints have been reimplemented and the new implementation does less automatic warping of the cursor.

Packaging changes:

• wlroots 0.17.2 is required.
• The official upstream river repository has moved to https://codeberg.org/river/river

Community:

• River has adopted a Code of Conduct
