Version history
===============

To find out how to migrate your application from a previous version of
APScheduler, see the :doc:`migration section <migration>`.

2.0.2
-----

* Removed the unique constraint from the "name" column in the SQLAlchemy
  job store

* Fixed output from Scheduler.print_jobs() which did not previously output
  a line ending at the end


2.0.1
-----

* Fixed cron style jobs getting wrong default values


2.0.0
-----

* Added configurable job stores with several persistent back-ends
  (shelve, SQLAlchemy and MongoDB)

* Added the possibility to listen for job events (execution, error, misfire,
  finish) on a scheduler

* Added an optional start time for cron-style jobs

* Added optional job execution coalescing for situations where several
  executions of the job are due

* Added an option to limit the maximum number of concurrenctly executing
  instances of the job

* Allowed configuration of misfire grace times on a per-job basis

* Allowed jobs to be explicitly named

* All triggers now accept dates in string form (YYYY-mm-dd HH:MM:SS)

* Jobs are now run in a thread pool; you can either supply your own PEP 3148
  compliant thread pool or let APScheduler create its own

* Maximum run count can be configured for all jobs, not just those using
  interval-based scheduling

* Fixed a v1.x design flaw that caused jobs to be executed twice when the
  scheduler thread was woken up while still within the allowable range of their
  previous execution time (issues #5, #7)

* Changed defaults for cron-style jobs to be more intuitive -- it will now
  default to all minimum values for fields lower than the least significant
  explicitly defined field


1.3.1
-----

* Fixed time difference calculation to take into account shifts to and from
  daylight saving time


1.3.0
-----

* Added __repr__() implementations to expressions, fields, triggers, and jobs
  to help with debugging

* Added the dump_jobs method on Scheduler, which gives a helpful listing of
  all jobs scheduled on it

* Fixed positional weekday (3th fri etc.) expressions not working except in
  some edge cases (fixes #2)

* Removed autogenerated API documentation for modules which are not part of
  the public API, as it might confuse some users

.. Note:: Positional weekdays are now used with the **day** field, not
   **weekday**.


1.2.1
-----

* Fixed regression: add_cron_job() in Scheduler was creating a CronTrigger with
  the wrong parameters (fixes #1, #3)

* Fixed: if the scheduler is restarted, clear the "stopped" flag to allow
  jobs to be scheduled again


1.2.0
-----

* Added the ``week`` option for cron schedules

* Added the ``daemonic`` configuration option

* Fixed a bug in cron expression lists that could cause valid firing times
  to be missed

* Fixed unscheduling bound methods via unschedule_func()

* Changed CronTrigger constructor argument names to match those in Scheduler


1.01
----

* Fixed a corner case where the combination of hour and day_of_week parameters
  would cause incorrect timing for a cron trigger
