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

- The previous release accidentally changed several files from Unix to DOS
line-endings. Fix that.

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

- [varLib] Temporarily revert the fix to ``load_masters()``, which caused a
crash in ``interpolate_layout()`` when ``deepcopy``-ing OTFs.

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

- [varLib] ``load_masters()`` now actually assigns the fonts it loads to the
source.font attributes.
- [varLib] Fixed an MVAR table generation crash when sparse masters were
involved.
- [voltLib] ``parse_coverage_()`` returns a tuple instead of an ast.Enum.
- [feaLib] A MarkClassDefinition inside a block is no longer doubly indented
compared to the rest of the block.

current glyph indices (1443, 1447).
- [ufoLib] Replace deprecated calls to ``getbytes`` and ``setbytes`` with new
equivalent ``readbytes`` and ``writebytes`` calls. ``fs`` >= 2.2 no required.
- [varLib] Allow loading masters from TTX files as well (1441).

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

- [hmtx/vmtx]: Allow to compile/decompile ``hmtx`` and ``vmtx`` tables even

``stylename`` (1438).

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

- [_m_a_x_p] Include ``maxComponentElements`` in ``maxp`` table's recalculation.

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

- [psCharStrings] In ``encodeFloat`` function, use float's "general format" with
8 digits of precision (i.e. ``%8g``) instead of ``str()``. This works around
a macOS rendering issue when real numbers in CFF table are too long, and
also makes sure that floats are encoded with the same precision in python 2.7
and 3.x (1430, googlei18n/ufo2ft306).
- [_n_a_m_e/fontBuilder] Make ``_n_a_m_e_table.addMultilingualName`` also add
Macintosh (platformID=1) names by default. Added options to ``FontBuilder``
``setupNameTable`` method to optionally disable Macintosh or Windows names.
(1359, 1431).
- [varLib] Make ``build`` optionally accept a ``DesignSpaceDocument`` object,
instead of a designspace file path. The caller can now set the ``font``
attribute of designspace's sources to a TTFont object, thus allowing to
skip filenames manipulation altogether (1416, 1425).

a DefaultLangSys record (1408, 135a4a1).

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

- [varLib] Work around macOS rendering issue for composites without gvar entry (1381).

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

- [varLib] Support generation of CFF2 variable fonts. ``model.reorderMasters()``
now supports arbitrary mapping. Fix handling of overlapping ranges for feature
variations (1400).
- [cffLib, subset] Code clean-up and fixing related to CFF2 support.
- [ttLib.tables.ttProgram] Use raw strings for regex patterns (1389).
- [fontbuilder] Initial support for building CFF2 fonts. Set CFF's
``FontMatrix`` automatically from unitsPerEm.
- [plistLib] Accept the more general ``collections.Mapping`` instead of the
specific ``dict`` class to support custom data classes that should serialize
to dictionaries.

----------------------------
- [subset] subsetter bug fix with variable fonts.
- [varLib.featureVar] Improve FeatureVariations generation with many rules.
- [varLib] Enable sparse masters when building variable fonts:
https://github.com/fonttools/fonttools/pull/1368issuecomment-437257368
- [varLib.mutator] Add IDEF for GETVARIATION opcode, for handling hints in an
instance.
- [ttLib] Ignore the length of kern table subtable format 0

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

- [ufoLib] Make ``UFOWriter`` a subclass of ``UFOReader``, and use mixins
for shared methods (1344).
- [featureVars] Fixed normalization error when a condition's minimum/maximum
attributes are missing in designspace ``<rule>`` (1366).
- [setup.py] Added ``[plot]`` to extras, to optionally install ``matplotlib``,
needed to use the ``fonTools.varLib.plot`` module.
- [varLib] Take total bounding box into account when resolving model (7ee81c8).
If multiple axes have the same range ratio, cut across both (62003f4).
- [subset] Don't error if ``STAT`` has no ``AxisValue`` tables.
- [fontBuilder] Added a new submodule which contains a ``FontBuilder`` wrapper
class around ``TTFont`` that makes it easier to create a working TTF or OTF
font from scratch with code. NOTE: the API is still experimental and may
change in future versions.

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

- [ufoLib] Merged the `ufoLib <https://github.com/unified-font-objects/ufoLib>`__
master branch into a new ``fontTools.ufoLib`` package (1335, 1095).
Moved ``ufoLib.pointPen`` module to ``fontTools.pens.pointPen``.
Moved ``ufoLib.etree`` module to ``fontTools.misc.etree``.
Moved ``ufoLib.plistlib`` module to ``fontTools.misc.plistlib``.
To use the new ``fontTools.ufoLib`` module you need to install fonttools
with the ``[ufo]`` extra, or you can manually install the required additional
dependencies (cf. README.rst).
- [morx] Support AAT action type to insert glyphs and clean up compilation
of AAT action tables (4a1871f, 2011ccf).
- [subset] The ``--no-hinting`` on a CFF font now also drops the optional
hinting keys in Private dict: ``ForceBold``, ``LanguageGroup``, and
``ExpansionFactor`` (1322).
- [subset] Include nameIDs referenced by STAT table (1327).
- [loggingTools] Added ``msg=None`` argument to
``CapturingLogHandler.assertRegex`` (0245f2c).
- [varLib.mutator] Implemented ``FeatureVariations`` instantiation (1244).
- [g_l_y_f] Added PointPen support to ``_TTGlyph`` objects (1334).

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

- [feaLib] Skip building noop class PairPos subtables when Coverage is NULL
(1318).
- [ttx] Expose the previously reserved bit flag ``OVERLAP_SIMPLE`` of
glyf table's contour points in the TTX dump. This is used in some
implementations to specify a non-zero fill with overlapping contours (1316).
- [ttLib] Added support for decompiling/compiling ``TS1C`` tables containing
VTT sources for ``cvar`` variation table (1310).
- [varLib] Use ``fontTools.designspaceLib`` to read DesignSpaceDocument. The
``fontTools.varLib.designspace`` module is now deprecated and will be removed
in future versions. The presence of an explicit ``axes`` element is now
required in order to build a variable font (1224, 1313).
- [varLib] Implemented building GSUB FeatureVariations table from the ``rules``
element of DesignSpace document (1240, 713, 1314).
- [subset] Added ``--no-layout-closure`` option to not expand the subset with
the glyphs produced by OpenType layout features. Instead, OpenType features
will be subset to only rules that are relevant to the otherwise-specified
glyph set (43, 1121).

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

- [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).

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

- [varLib] Improved support-resolution algorithm. Previously, the on-axis
masters would always cut the space. They don't anymore. That's more
consistent, and fixes the main issue Erik showed at TYPO Labs 2017.
Any varfont built that had an unusual master configuration will change
when rebuilt (42bef17, a523a697,
https://github.com/googlei18n/fontmake/issues/264).
- [varLib.models] Added a ``main()`` entry point, that takes positions and
prints model results.
- [varLib.plot] Added new module to plot a designspace's
VariationModel. Requires ``matplotlib``.
- [varLib.mutator] Added -o option to specify output file path (2ef60fa).
- [otTables] Fixed IndexError while pruning of HVAR pre-write (6b6c34a).
- [varLib.models] Convert delta array to floats if values overflows signed
short integer (0055f94).

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

- [otBase] Don't fail during ``ValueRecord`` copy if src has more items.
We drop hinting in the subsetter by simply changing ValueFormat, without
cleaning up the actual ValueRecords. This was causing assertion error if
a variable font was subsetted without hinting and then passed directly to
the mutator for instantiation without first it saving to disk.

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

- [varLib] Don't remap the same ``DeviceTable`` twice in VarStore optimizer
(1206).
- [varLib] Add ``--disable-iup`` option to ``fonttools varLib`` script,
and a ``optimize=True`` keyword argument to ``varLib.build`` function,
to optionally disable IUP optimization while building varfonts.
- [ttCollection] Fixed issue while decompiling ttc with python3 (1207).

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

- [ttGlyphPen] Decompose composite glyphs if any components' transform is too
large to fit a ``F2Dot14`` value, or clamp transform values that are
(almost) equal to +2.0 to make them fit and avoid decomposing (1200,
1204, 1205).
- [ttx] Added new ``-g`` option to dump glyphs from the ``glyf`` table
splitted as individual ttx files (153, 1035, 1132, 1202).
- Copied ``ufoLib.filenames`` module to ``fontTools.misc.filenames``, used
for the ttx split-glyphs option (1202).
- [feaLib] Added support for ``cvParameters`` blocks in Character Variant
feautures ``cv01-cv99`` (860, 1169).
- [Snippets] Added ``checksum.py`` script to generate/check SHA1 hash of
ttx files (1197).
- [varLib.mutator] Fixed issue while instantiating some variable fonts
whereby the horizontal advance width computed from ``gvar`` phantom points
could turn up to be negative (1198).
- [varLib/subset] Fixed issue with subsetting GPOS variation data not
picking up ``ValueRecord`` ``Device`` objects (54fd71f).
- [feaLib/voltLib] In all AST elements, the ``location`` is no longer a
required positional argument, but an optional kewyord argument (defaults
to ``None``). This will make it easier to construct feature AST from
code (1201).

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

- [designspaceLib] Added an optional ``lib`` element to the designspace as a
whole, as well as to the instance elements, to store arbitrary data in a
property list dictionary, similar to the UFO's ``lib``. Added an optional
``font`` attribute to the ``SourceDescriptor``, to allow operating on
in-memory font objects (1175).
- [cffLib] Fixed issue with lazy-loading of attributes when attempting to
set the CFF TopDict.Encoding (1177, 1187).
- [ttx] Fixed regression introduced in 3.22.0 that affected the split tables
``-s`` option (1188).
- [feaLib] Added ``IncludedFeaNotFound`` custom exception subclass, raised
when an included feature file cannot be found (1186).
- [otTables] Changed ``VarIdxMap`` to use glyph names internally instead of
glyph indexes. The old ttx dumps of HVAR/VVAR tables that contain indexes
can still be imported (21cbab8, 38a0ffb).
- [varLib] Implemented VarStore optimizer (1184).
- [subset] Implemented pruning of GDEF VarStore, HVAR and MVAR (1179).
- [sfnt] Restore backward compatiblity with ``numFonts`` attribute of
``SFNTReader`` object (1181).
- [merge] Initial support for merging ``LangSysRecords`` (1180).
- [ttCollection] don't seek(0) when writing to possibly unseekable strems.
- [subset] Keep all ``--name-IDs`` from 0 to 6 by default (1170, 605, 114).
- [cffLib] Added ``width`` module to calculate optimal CFF default and
nominal glyph widths.
- [varLib] Don’t fail if STAT already in the master fonts (1166).
