### Tools

- posegment now correctly segments Japanese strings with half width punctuation sign (issue 3280).
- pocount now outputs csv header in one line. It also outputs using color.
- `buildxpi` was adjusted to current Mozilla needs

### Languages

- Fixed plural form for Macedonian, Songhay, Tajik, Slovenian and Turkish.
- Added plural forms for Bengali (Bangladesh), Konkani, Kashmiri, Sanskrit, Silesian and Yue (Cantonese).
- Renamed Oriya to Odia.
- Altered Manipuri name to include its most common name Meithei.

### Setup

- Fixed Inno Setup builds allowing to easily install Translate Toolkit on Windows using the `pip` installer. Commands are compiled to .exe files.
- Updated installation instructions for Windows

### API changes

- Dropped `translate.misc.dictutils.ordereddict` in favor of `collections.OrderedDict`.
- Added encoding handling in base `TranslationStore` class exposing a single API.
- Encoding detection in `TranslationStore` has been improved.
- Standardized UnitClass definition across `TranslationStore` subclasses.
- `translate.misc.multistring.multistring`:
  - Fixed list coercion to text
  - Fixed comparison regression with multistrings (issue 3404).
  - Re-added `str` method (issue 3428).
  - Fixed `__hash__` (issue 3434).

### API deprecation

- Passing non-ASCII bytes to the `multistring` class has been deprecated, as well as the `encoding` argument to it. Applications should always construct `multistring` objects by passing characters (`unicode` in Python 2, `str` in Python 3), not bytes. Support for passing non-ASCII bytes will be removed in the next version.
- `TxtFile.getoutput()` and `dtdfile.getoutput()` have been deprecated. Either call `bytes(<file_instance>)` or use the `file_instance.serialize()` API if you need to get the serialized store content of a `TxtFile` or `dtdfile` instance.

### General

- Dropped support for Python 2.6 since it is no longer supported by the Python Foundation. Sticking to it was making us difficult to maintain code while we move to Python 3.
- Misc docs cleanups.
- Added more tests.
- Increased Python code health.
- Legacy, deprecated and unused code cleansing:
  - Dropped code for no longer supported Python versions.
  - Removed unused code from various places across codebase.
  - The legacy `translate.search.indexing.PyLuceneIndexer1` was removed.
  - The deprecated `translate.storage.properties.find_delimiter()` was removed and replaced by the `translate.storage.properties.Dialect.find_delimiter()` class method.
  - Python scripts are now available via console_scripts entry point, thus allowing to drop dummy files for exposing the scripts.

...and loads of general code cleanups and of course many many bugfixes.
