Fonttools

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

- [feaLib] Fixed issue whereby lookups from DFLT/dflt were not included in the
DFLT/non-dflt language systems (1307).
- [graphite] Fixed issue on big-endian architectures (e.g. ppc64) (1311).
- [subset] Added ``--layout-scripts`` option to add/exclude set of OpenType
layout scripts that will be preserved. By default all scripts are retained
(``'*'``) (1303).

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

- [feaLib] In the OTL table builder, when the ``name`` table is excluded
from the list of tables to be build, skip compiling ``featureNames`` blocks,
as the records referenced in ``FeatureParams`` table don't exist (68951b7).
- [otBase] Try ``ExtensionLookup`` if other offset-overflow methods fail
(05f95f0).
- [feaLib] Added support for explicit ``subtable;`` break statements in
PairPos lookups; previously these were ignored (1279, 1300, 1302).
- [cffLib.specializer] Make sure the stack depth does not exceed maxstack - 1,
so that a subroutinizer can insert subroutine calls (1301,
https://github.com/googlei18n/ufo2ft/issues/266).
- [otTables] Added support for fixing offset overflow errors occurring inside
``MarkBasePos`` subtables (1297).
- [subset] Write the default output file extension based on ``--flavor`` option,
or the value of ``TTFont.sfntVersion`` (d7ac0ad).
- [unicodedata] Updated Blocks, Scripts and ScriptExtensions for Unicode 11
(452c85e).
- [xmlWriter] Added context manager to XMLWriter class to autoclose file
descriptor on exit (1290).
- [psCharStrings] Optimize the charstring's bytecode by encoding as integers
all float values that have no decimal portion (8d7774a).
- [ttFont] Fixed missing import of ``TTLibError`` exception (1285).
- [feaLib] Allow any languages other than ``dflt`` under ``DFLT`` script
(1278, 1292).

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

- [featureVars] Added experimental module to build ``FeatureVariations``
tables. Still needs to be hooked up to ``varLib.build`` (1240).
- [fixedTools] Added ``otRound`` to round floats to nearest integer towards
positive Infinity. This is now used where we deal with visual data like X/Y
coordinates, advance widths/heights, variation deltas, and similar (1274,
1248).
- [subset] Improved GSUB closure memoize algorithm.
- [varLib.models] Fixed regression in model resolution (180124, 1269).
- [feaLib.ast] Fixed error when converting ``SubtableStatement`` to string
(1275).
- [varLib.mutator] Set ``OS/2.usWeightClass`` and ``usWidthClass``, and
``post.italicAngle`` based on the 'wght', 'wdth' and 'slnt' axis values
(1276, 1264).
- [py23/loggingTools] Don't automatically set ``logging.lastResort`` handler
on py27. Moved ``LastResortLogger`` to the ``loggingTools`` module (1277).

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

- [ttGlyphPen] Issue a warning and skip building non-existing components
(https://github.com/googlei18n/fontmake/issues/411).
- [tests] Fixed issue running ttx_test.py from a tagged commit.

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

- [designspaceLib] Added new ``conditionSet`` element to ``rule`` element in
designspace document. Bumped ``format`` attribute to ``4.0`` (previously,
it was formatted as an integer). Removed ``checkDefault``, ``checkAxes``
methods, and any kind of guessing about the axes when the ``<axes>`` element
is missing. The default master is expected at the intersection of all default
values for each axis (1254, 1255, 1267).
- [cffLib] Fixed issues when compiling CFF2 or converting from CFF when the
font has an FDArray (1211, 1271).
- [varLib] Avoid attempting to build ``cvar`` table when ``glyf`` table is not
present, as is the case for CFF2 fonts.
- [subset] Handle None coverages in MarkGlyphSets; revert commit 02616ab that
sets empty Coverage tables in MarkGlyphSets to None, to make OTS happy.
- [ttFont] Allow to build glyph order from ``maxp.numGlyphs`` when ``post`` or
``cmap`` are missing.
- [ttFont] Added ``__len__`` method to ``_TTGlyphSet``.
- [glyf] Ensure ``GlyphCoordinates`` never overflow signed shorts (1230).
- [py23] Added alias for ``itertools.izip`` shadowing the built-in ``zip``.
- [loggingTools] Memoize ``log`` property of ``LogMixin`` class (fbab12).
- [ttx] Impoved test coverage (1261).
- [Snippets] Addded script to append a suffix to all family names in a font.
- [varLib.plot] Make it work with matplotlib >= 2.1 (b38e2b).

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

- [designspace] Added a new optional ``layer`` attribute to the source element,
and a corresponding ``layerName`` attribute to the ``SourceDescriptor``
object (1253).
Added ``conditionset`` element to the ``rule`` element to the spec, but not
implemented in designspace reader/writer yet (1254).
- [varLib.models] Refine modeling one last time (0ecf5c5).
- [otBase] Fixed sharing of tables referred to by different offset sizes
(795f2f9).
- [subset] Don't drop a GDEF that only has VarStore (fc819d6). Set to None
empty Coverage tables in MarkGlyphSets (02616ab).
- [varLib]: Added ``--master-finder`` command-line option (1249).
- [varLib.mutator] Prune fvar nameIDs from instance's name table (1245).
- [otTables] Allow decompiling bad ClassDef tables with invalid format, with
warning (1236).
- [varLib] Make STAT v1.2 and reuse nameIDs from fvar table (1242).
- [varLib.plot] Show master locations. Set axis limits to -1, +1.
- [subset] Handle HVAR direct mapping. Passthrough 'cvar'.
Added ``--font-number`` command-line option for collections.
- [t1Lib] Allow a text encoding to be specified when parsing a Type 1 font
(1234). Added ``kind`` argument to T1Font constructor (c5c161c).
- [ttLib] Added context manager API to ``TTFont`` class, so it can be used in
``with`` statements to auto-close the file when exiting the context (1232).
