node-cron 4.5.0

v4.5.0

on Node.js NPM

Added

• lastRun() introspection getter on ScheduledTask: returns { date, result } after a successful execution, { date, error } after a failed one, or null before the first run.
• Extended day-of-week tokens: <weekday>#<nth> (nth weekday of the month, e.g. 1#1 for the first Monday) and <weekday>L (last weekday of the month, e.g. 5L for the last Friday).

Performance

• Cache Intl.DateTimeFormat instances per timezone instead of rebuilding on every call.
• Parse the cron expression once per TimeMatcher instead of re-parsing in MatcherWalker.
• Compute the GMT offset lazily (only when formatting ISO strings, not during the next-run search).
• Replace crypto.randomBytes with crypto.randomUUID for internal ID generation.
• Skip setTimeout jitter wrapper when maxRandomDelay is zero.
• Bundle dist into flat files instead of preserving the module tree (reduces import time).

Fixed

• Flaky should schedule a task test: poll for the first execution instead of asserting an exact count after a fixed sleep.

Changed

• Renamed internal functions interprete to interpret and appendSeccondExpression to appendSecondExpression.
• Rewritten README and package metadata to surface scheduling capabilities (overlap prevention, distributed coordination, background tasks).
