Some notable changes in this release:

• pool: All pool types now panic if configured after use.
• pool: ContextPool and ResultContextPool now always cancels its context when Wait() returns.
• pool: ContextPool and ResultContextPool now cancels its context when a task panics.
• panics: panics.RecoveredPanic and panics.NewRecoveredPanic(...) have been renamed panics.Recovered and panics.NewRecovered(...) respectively.
• panics: panics.Recovered no longer implements error directly, which would previously have unintended side effects - instead, it can be converted into an error implementation explicitly with (*Recovered).AsError().
• panics: Added a package-level panics.Try(...) for recovering from panics from a single function.
• multierrors: For pools that return multiple errors:
  • in Go 1.20 and later, conc now uses the standard library multi-error implementation
  • in Go 1.19 and earlier, conc now uses the go.uber.org/multierr library

Some of the changes listed above are breaking changes - this package is currently pre-1.0, and there are likely to be other breaking changes before a 1.0 release as we stabilize the APIs and tweak defaults. Please open an issue if you have questions, concerns, or requests that you'd like addressed before the 1.0 release. Currently, a 1.0 is targeted for March 2023.
