Meeting Minutes

Agenda

From @evanlinjin :

• rust-bitcoin
  • Tobin will communicate changes better with us.
  • Tobin warns of rapid changes in rust-bitcoin before 1.0 (we shouldn't have BDK 1.0 before rust-bitcoin 1.0). Miniscript 1.0 was a mistake.
• ldk-node (tnull)
  • Timeline!
  • If we don't release stable BDK in time, can be backport BDK 0.28 to use latest rust-bitcoin. Do we need to update bdk_electrum, bdk_esplora first?
  • Versioning for ChangeSets?
• Reviews
  • We want to move fast, but also want everyone to understand the changes being made.
