Meeting Notes 2025 05 12

LDK Releases

• 0.1.2 (https://github.com/lightningdevkit/rust-lightning/milestone/46)
• 0.1.3 came out a week and a half ago
  • https://github.com/lightningdevkit/rust-lightning/milestone/47
  • Be sure to upgrade, there are important fixes
  • We had a fix go out over the weekend, so there will be 0.1.4 for this in the next day or so
  • Only impacts async persistence users, which is an alpha feature
• 0.2 (https://github.com/lightningdevkit/rust-lightning/milestone/17)
  • Still cooking the major features here, hopefully will have dual funding and 0-fee commitments soonish. Probably not before the vegas conf at the end of May.
  • Should get more serious about this going into June

LDK Node Release

- 0.5 (https://github.com/lightningdevkit/ldk-node/milestone/5)
    - This release is out!
    - We shipped the RC a few weeks ago and nothing came up in testing
    - For the bindings, we waited for LDK 0.1.3 to release so it’s included in the binary release. Rust we shipped a day or so before that 
- Looking to 0.6 now 

Language bindings

- There was a 0.1.3 release w/ language bindings on the LDK side, may or may not to 0.1.4 bindings since there are no async persistence bindings users 

Developer support

- Added an LLMS text file to the website for large language models 
    - Doesn’t point to docs.rs right now, just the LDK website markdown files 
    - docs.rs tends to be LDK’s most up-to-date documentation 
- Going forward, if anyone has ideas for how to improve docs in the future for that use case, let Conor know 

Feature progress

- Attributable failures
    - Joost updated ldk-sample and gave it to acinq for interop testing here 
- Async payments
    - Arik progressing on next trampoline PR, debugging a bit rn 
    - Progressing on shaavan’s offers flow PR which further async payments work is being based on 
- RGS
- VSS
    - Not prioritized at the moment but it works, there is a server and client out there
    - VSS phase 2 multi-device part is not yet implemented 
- Dual funding
    - 3637 is close, interactive state signing 
    - This is the last part we need before accepting DF channels from peers 
    - Then we’ll do contributing inputs, which is in draft 
- Splicing
    - We have a few PRs in-flight, jeff has his exchange splice_locked message PR that had some changes last week and will be getting reviewed this week
    - We have optout’s PR to finish the negotiation parts that’s getting closer, needs more review this week 
    - Wpaulino last week working on wrapping up the monitor side of things, good progress so should be under review soon
