Release Notes

djc/bb8 (bb8)

v0.9.0: 0.9.0

Compare Source

bb8 0.9.0 (and bb8-postgres 0.9.0, bb8-redis 0.18.0) adopts RPITIT (first stabilized in Rust 1.75) to drop the dependency on async_trait. This comes at the cost of raising the MSRV for these new releases to 1.75. If any bugs are found, I will consider releasing 0.8.x upgrades until such time as Tokio bumps its MSRV to 1.75.

What's Changed

• Add Discord link to README by @​djc in #​228
• Apply suggestions from clippy 1.83 by @​djc in #​229
• Get token from environment by @​djc in #​231
• Replace async_trait with native async fns by @​gahag-cw in #​230
