Changelog
=========

Here you can see the full list of changes between each Wiggelen release.


Version 0.2.0
-------------

Released on September 2nd 2013.

- Auto scale tracks in distance calculation if needed (the metrics in
  `wiggelen.distance` are not defined on the (0, 1) interval).
- Add min,posmin,max fields to track index.
- Optionally consider edges in `wiggelen.fill` (`only_edges` argument).
- Introduce the `plot` module for visualizing tracks.
- Rename command line ``visualize`` function to ``plot``.


Version 0.1.6
-------------

Released on August 8th 2013.

- Support `fixedStep` definitions without `step` argument. This is not valid
  by the spec, so a practical consideration. Fixes
  `issue #1 <https://github.com/martijnvermaat/wiggelen/issues/1>`_.


Version 0.1.5
-------------

Released on July 21st 2013.

- Optional track name (`-n` or `--name`) and description (`-d` or
  `--description`) for command line functions.
- Command line argument `-n` or `--no-indices` for `merge` has been
  renamed to `-x` or `--no-indices`.
- Slight performance improvement in parsing.


Version 0.1.4
-------------

Released on July 15th 2013.

- Fix parsing tracks in fixedStep mode.
- Intervals BED track is now correctly written tab-delimited.
- Fix distance module on Python 3.2+.


Version 0.1.3
-------------

Released on June 11th 2013.

- Fix distance calculation on values below threshold. Positions where both
  values are below the given threshold are ignored.


Version 0.1.2
-------------

Released on May 6th 2013.

- Coverage intervals. Module `intervals` implements extraction of coverage
  intervals from walkers and writing them to BED files. Coverage intervals
  with an optional value threshold can be written for any wiggle track to a
  BED file using the command line `coverage` command.
- Add name and description arguments to `write` (Jeroen Laros).
- Fix dependencies declaration in setup.py (only affects Python 2.6).
