Changelog
==============

1.2.0 (2022-01-14)
------------------

- Enforce validation for day=1. Before this release we used to support day=0 and it was silently glided to day=1 to support having both day in day in 4th field when it came to have 6fields cron forms (second repeat). It will now raises a CroniterBadDateError. See https://github.com/kiorky/croniter/issues/6

- Enforce validation for month=1. Before this release we used to support month=0 and it was silently glided to month=1 to support having both day in month in 4th field when it came to have 6fields cron forms (second repeat).

-------------------

- better type checks [kiorky]


1.0.13 (2021-05-06)

- Review support support for hashed/random/keyword expression and add expanders reactor
  [ kiorky ]


1.0.11 (2021-04-07)
-------------------

- fix bug: bad case:``0 6 30 3 *``
  [zed2015(zhangchi)]
- Add support for ``L`` in the day_of_week component.  This enable expressions like ``* * * * L4``, which means last Thursday of the month.  This resolves #159.
  [Kintyre]
- Create ``CroniterUnsupportedSyntaxError`` exception for situations where CRON syntax may be valid but some combinations of features is not supported.
  Currently, this is used when the ``day_of_week`` component has a combination of literal values and nth/last syntax at the same time.
  For example, ``0 0 * * 1,L6`` or ``0 0 * * 15,sat#1`` will both raise this exception because of mixing literal days of the week with nth-weekday or last-weekday syntax.
  This *may* impact existing cron expressions in prior releases, because ``0 0 * * 15,sat#1`` was previously allowed but incorrectly handled.
  [Kintyre]

- Update ``croniter_range()`` to allow an alternate ``croniter`` class to be used.  Helpful when using a custom class derived from croniter.
  [Kintyre]


1.0.10 (2021-03-25)
-------------------

- Remove external library ``natsort``.
  Sorting of cron expression components now handled with ``sorted()`` with a custom ``key`` function.
  [Kintyre]



1.0.9 (2021-03-23)
------------------

- Remove futures dependency
  [kiorky]


1.0.8 (2021-03-06)
------------------

- Update `_expand` to lowercase each component of the expression.
  This is in relation to #157. With this change, croniter accepts and correctly handles `* * 10-L * *`.
  [cuu508]


1.0.7 (2021-03-02)
------------------

- Fix _expand to reject int literals with underscores
  [cuu508]
- Remove a debug statement to make flake8 happy

  [kiorky]

1.0.1 (2021-01-06)
------------------
- no changes, just to make sense with new semver2 (making croniter on a stable state)
  [kiorky]


0.3.37 (2020-12-31)
-------------------

- Added Python 3.8 and 3.9 support
  [eumiro]


0.3.36 (2020-11-02)
-------------------

- Updated docs section regarding ``max_years_between_matches`` to be more shorter and hopefully more relevant.
  [Kintyre]
- Don't install tests
  [scop]


0.3.35 (2020-10-11)
-------------------

- Handle L in ranges. This fixes #142.
  [kiorky]
- Add a new initialization parameter ``max_years_between_matches`` to support finding the next/previous date beyond the default 1 year window, if so desired.  Updated README to include additional notes and example of this usage.  Fixes #145.
  [Kintyre]
- The ``croniter_range()`` function was updated to automatically determines the appropriate ``max_years_between_matches`` value, this preventing handling of the ``CroniterBadDateError`` exception.
  [Kintyre]
- Updated exception handling classes:  ``CroniterBadDateError`` now only
  applies during date finding operations (next/prev), and all parsing errors can now be caught using ``CroniterBadCronError``.  The ``CroniterNotAlphaError`` exception is now a subclass of ``CroniterBadCronError``.  A brief description of each exception class was added as an inline docstring.
  [Kintyre]
- Updated iterable interfaces to replace the ``CroniterBadDateError`` with ``StopIteration`` if (and only if) the ``max_years_between_matches`` argument is provided.  The rationale here is that if the user has specified the max tolerance between matches, then there's no need to further inform them of no additional matches.  Just stop the iteration.  This also keeps backwards compatibility.
  [Kintyre]
- Minor docs update
  [Kintyre]
