Fonttools

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

- [setup] We no longer use versioneer.py to compute fonttools version
from git metadata, as this has caused issues for some users (767).
Now we bump the version strings manually with a custom ``release``
command of setup.py script.

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

- [ttLib] Implemented STAT table from OpenType 1.8 (758)
- [cffLib] Fixed decompilation of CFF fonts containing non-standard
key/value pairs in FontDict (issue 740; PR 744)
- [py23] minor: in ``round3`` function, allow the second argument to be
``None`` (757)
- The standalone ``sstruct`` and ``xmlWriter`` modules, deprecated
since vesion 3.2.0, have been removed. They can be imported from the
``fontTools.misc`` package.

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

- [py23] optimized performance of round3 function; added backport for
py35 math.isclose() (9d8dacb)
- [subset] fixed issue with 'narrow' (UCS-2) Python 2 builds and
``--text``/``--text-file`` options containing non-BMP chararcters
(16d0e5e)
- [varLib] fixed issuewhen normalizing location values (8fa2ee1, 749)
- [inspect] Made it compatible with both python2 and python3 (167ee60,
748). Thanks pnemade

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

- [varLib] Do not emit null axes in fvar (1bebcec). Thanks robmck-ms
- [varLib] Handle fonts without GPOS (7915a45)
- [merge] Ignore LangSys if None (a11bc56)
- [subset] Fix subsetting MathVariants (78d3cbe)
- [OS/2] Fix "Private Use (plane 15)" range (08a0d55). Thanks mashabow

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

- [OS/2] fix checking ``fsSelection`` bits matching ``head.macStyle``
bits
- [varLib] added ``--build-HVAR`` option to generate ``HVAR`` table for
fonts with TrueType outlines. For ``CFF2``, it is enabled by default.

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

- [varLib] Improve support for OpenType 1.8 Variable Fonts:
- Implement GDEF's VariationStore
- Implement HVAR/VVAR tables
- Partial support for loading MutatorMath .designspace files with
varLib.designspace module
- Add varLib.models with Variation fonts interpolation models
- Implement GSUB/GPOS FeatureVariations
- Initial support for interpolating and merging OpenType Layout tables
(see ``varLib.interpolate_layout`` and ``varLib.merger`` modules)
- [API change] Change version to be an integer instead of a float in
XML output for GSUB, GPOS, GDEF, MATH, BASE, JSTF, HVAR, VVAR, feat,
hhea and vhea tables. Scripts that set the Version for those to 1.0
or other float values also need fixing. A warning is emitted when
code or XML needs fix.
- several bug fixes to the cffLib module, contributed by Adobe's
readroberts
- The XML output for CFF table now has a 'major' and 'minor' elements
for specifying whether it's version 1.0 or 2.0 (support for CFF2 is
coming soon)
- [setup.py] remove undocumented/deprecated ``extra_path`` Distutils
argument. This means that we no longer create a "FontTools" subfolder
in site-packages containing the actual fontTools package, as well as
the standalone xmlWriter and sstruct modules. The latter modules are
also deprecated, and scheduled for removal in upcoming releases.
Please change your import statements to point to from fontTools.misc
import xmlWriter and from fontTools.misc import sstruct.
- [scripts] Add a 'fonttools' command-line tool that simply runs
``fontTools.*`` sub-modules: e.g. ``fonttools ttx``,
``fonttools subset``, etc.
- [hmtx/vmts] Read advance width/heights as unsigned short (uint16);
automatically round float values to integers.
- [ttLib/xmlWriter] add 'newlinestr=None' keyword argument to
``TTFont.saveXML`` for overriding os-specific line endings (passed on
to ``XMLWriter`` instances).
- [versioning] Use versioneer instead of ``setuptools_scm`` to
dynamically load version info from a git checkout at import time.
- [feaLib] Support backslash-prefixed glyph names.
