• daemon serialized task state with wrong field name (#587) (688d465)
• expand inverted ranges with wrap-around instead of silently swapping (#602) (a10ae53)

Changed

• replace chai and sinon with native vitest assertions (#590) (d29d07a)

v4.5.0

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.
