**Implemented enhancements:**
- Warn reference lenth discordancy between alignment and mappability file

**Fixed bugs:**
- Add forgetted initial rotate for mappability array
- BitArray length shortage if mappability tracks include positions which are out
of range of alignment file reference length

**Fixed bugs:**
- BitArray length shortage for reverse strand reads
- BitArray implementation fails for chromosomes which have no mapped reads

**Implemented enhancements:**
- Add BitArray implementation
- Some refactoring

**Fixed bugs:**
- Shift size shorter than read length is not acceptable now
- Default window size for smoothing changes 30 to 15

**Known issues:**
- Progress display for bitarray calculation with multiprocessing is currently
disabled due to `multiprocessing.Queue` stuffing

**Implemented enhancements:**
- matplotlib delay import and now import error is not critical for calculation
- Add `--disable-progress` option
- Check python3.5 support
- Some refactoring

**Fixed bugs:**
- Fix unsorted input check (reference disorder)
- Fix progress bar problems
- Fix multiple line progress bar erasing
- Fix read count progress bar is not disabling when input has no index
- Fix progress bar is not disabled when stderr is not a tty
- Fix interfering mappability progress bar with multiline proggress bar
- Fix some python2 unicode problems
- Fix json serializing
- `__whole__` entry becomes null for python2
- serialize error for python3

- First release.
