  • Add metrics argument to Manager::recycle method.
  • Remove deprecated managed::sync module.
  • Remove deprecated managed::Pool::try_get method.
  • Bump up MSRV to 1.63 to match the one of tokio.

  • Fix bug causing the pool to exceed its max_size in the case of a recycling error.
  • Fix panic caused by an integer overflow in the case of a failing post_create hook.

v0.9.4

  • Fix HookError and HookErrorCause in re-exports

v0.9.3
