• Feature: New ObtainMulti method to acquire multiple locks atomically #70
• Feature: Lock.Refresh now accepts an Options.RetryStrategy and retries transient redis errors.
• Fix: a lost lock (refresh against a key whose value no longer matches) now returns ErrNotObtained immediately instead of being silently retried by the retry loop.
• Fix: withRetry surfaces the last transient error when retries are exhausted, instead of masking it as ErrNotObtained.
• Fix: when retries are interrupted by a cancelled context, return errors.Join(ErrNotObtained, ctx.Err()) (or the last transient error joined with ctx.Err()) so callers can match on both with errors.Is.
• Docs: clarify ExponentialBackoff formula and the behaviour of its min/max arguments (first wait is 4ms; pass min >= 16ms for a sensible floor, non-zero max to cap growth).
• Chore: bump go-redis/v9 to v9.19.0 and raise minimum Go to 1.25 #86.
• Docs: add an external watchdog example showing how to periodically call Lock.Refresh from caller code, keeping refresh cadence and error handling out of the library.
