  - 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])
+ - Protocol: Offers on nodes with only private channels are now payable (i.e. no more blinded path errors!). ([#8500])
  - 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])
  - pyln-client: plugin notifications parameters now exposed directly, not wrapped in `params` object. ([#8376])
  - Plugins: `bookkeeper` now explicitly assumes every transaction is in the same currency as the node (true unless you added manually) ([#8445])

 ### Fixed
 
+ - Certificates auto-generated by grpc-plugin, rest-plugin, and wss-proxy-plugin now include the required Authority Key Identifier and Key Usages extensions. ([#8495])
  - JSON-RPC: `fetchinvoice` is now more reliable. ([#8470])
  - lightningd: don't get confused with parallel ping commands. ([#8344])
  - libbacktrace works with macOS, so we get backtraces on crashes ([#8431])
