 ### Changed
 
+ - Build: we now use `uv` to build instead of poetry: see doc/getting-started/getting-started/installation.md ([#8249])
  - Protocol: We now insist that peers support `option_channel_type` (in CLN since 0.12.0 in late 2022, similar for other implementations). ([#8389])
  - Protocol: payment secret ('s' field) is now mandatory in BOLT11 payment requests for improved security. ([#8377])
  - wss-proxy.py was replaced by a rust version with support for multiple `wss-bind-addr`. If you install CLN from pre-compiled binaries you must remove the old wss-proxy directory first before installing CLN, usually ([#8080])
