DRAFT - Upgrading to v3

cron v3 is a major upgrade to the library that addresses all outstanding bugs, feature requests, and clarifications around usage. It is based on a merge of master (containing various fixes) and the v2 branch (containing a couple new features), with the addition of Go Modules support. It is currently in development.

These are the updates required:

• The v1 branch accepted an optional seconds field at the beginning of the cron spec. This is non-standard and has led to a lot of confusion. The new default parser conforms to the standard as described by the Cron wikipedia page. This behavior is not currently supported in v3.

Cron spec format

There are two cron spec formats in common usage:

• The "standard" cron format, described on the Cron wikipedia page and used by the cron Linux system utility.

• The cron format used by the Quartz Scheduler, commonly used for scheduled jobs in Java software

The original version of this package included an optional "seconds" field, which made it incompatible with both of these formats. Instead, the schedule parser has been extended to support both types.
