Meeting Notes 2024 07 22

LDK Releases

• 0.0.124 (https://github.com/lightningdevkit/rust-lightning/milestone/42)
  • Still a little ways to go
  • Things will be slow this week due to people traveling for Nashville
• 0.1 (https://github.com/lightningdevkit/rust-lightning/milestone/1)

LDK Node Release

• 0.4 (https://github.com/lightningdevkit/ldk-node/milestone/4)
  • Not much news since last meeting
  • Unified QR code PR landed
  • Minor api improvements coming
  • exposing more bolt 12 fields
  • capability for users to configure more routing things like cltv delta
  • Depending on bdk 1.0 release, we might go to 0.4 directly or might ship smaller improvements in 0.3.1
    • Bdk 1.0 will get a lot of performance improvements, like in wallet syncing. It currently requires the wallet to be held in a mutex atm that needs to be locked for the duration of the sync, which can be multiples of 10s, and no other wallet ops can happen in that time like getting an address
    • Also stuck on esplora backend for syncing, and 1.0 will allow us to mix/match blocking/async syncing backends and add bitcoind rpc support for example
