4.0.0

• Bugfixes
  • #35 Valid quartz range expression is considered invalid. Range validations should be contextual to cron definition.
  • #36 Cron mapping not working accurately where '?' symbol is supported.
  • #56 Incorrect mapping from UNIX Cron to QUARTZ expressions.
  • #57 BetweenDayOfWeekValueGenerator does not work for the first day of a month in some cases.
  • #58 Incorrect parsing of step values: "0 1/2 * * *" -> "0 /2 * * *".
  • #61 nextExecution over daylight savings is wrong.
  • #63 Both, a day-of-week AND a day-of-month parameter, should fail for QUARTZ.
  • #73 nextExecution not working as expected with CronType.QUARTZ: sometimes next(now) returns same value as next(next(now)).
  • #78 ExecutionTime.forCron fails on pattern "0 0/30 * * * ?".
  • #81 Incorrect date generation: cron-utils not correctly mapping some DoW values.
  • #86 Enhanced support for cron ranges: make strict range logic enforcements contextual to cron definition. Support QUARTZ ranges (L-3, 5-1) apart from UNIX ones (from<to).
• Features
  • #48 Add cron expressions builder
  • #87 Compare if two crons are equivalent
