- Update from version 2.11.1 to 2.12.1
- Update of rootfile
- Changelog
CHANGES BETWEEN 2.12.0 and 2.12.1
I. IMPORTANT BUG FIXES
- Loading CFF fonts sometimes made FreeType crash (bug introduced in
version 2.12.0)
- Loading a fully hinted TrueType glyph a second time (without
caching) sometimes yielded different rendering results if TrueType
hinting was active (bug introduced in version 2.12.0).
- The generation of the pkg-config file `freetype2.pc` was broken if
the build was done with cmake (bug introduced in version 2.12.0).
II. MISCELLANEOUS
- New option `--with-librsvg` for the `configure` script for better
FreeType demo support.
- The meson build no longer enforces both static and dynamic
versions of the library by default.
- The internal zlib library was updated to version 1.2.12. Note,
however, that FreeType is *not* affected by CVE-2018-25032 since
it only does decompression.
CHANGES BETWEEN 2.11.1 and 2.12.0
I. IMPORTANT CHANGES
- FreeType now handles OT-SVG fonts, to be controlled with
`FT_CONFIG_OPTION_SVG` configuration macro. By default, it can
only load the 'SVG ' table of an OpenType font. However, by using
the `svg-hooks` property of the new 'ot-svg' module it is possible
to register an external SVG rendering engine. The FreeType demo
programs have been set up to use 'librsvg' as the rendering
library.
This work was Moazin Khatti's GSoC 2019 project.
II. MISCELLANEOUS
- The handling of fonts with an 'sbix' table has been improved.
- Corrected bitmap offsets.
- A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes
FreeType ignore an 'sbix' table in a font, allowing applications
to access the font's outline glyphs.
- `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together
with their corresponding preprocessor macros `FT_HAS_SBIX` and
`FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables
as described in the OpenType specification.
- The internal 'zlib' code has been updated to be in sync with the
current 'zlib' version (1.2.11).
- The previously internal load flag `FT_LOAD_SBITS_ONLY` is now
public.
- Some minor improvements of the building systems, in particular
handling of the 'zlib' library (internal vs. external).
- Support for non-desktop Universal Windows Platform.
- Various other minor bug and documentation fixes.
- The `ftdump` demo program shows more information for Type1 fonts
if option `-n` is given.
- `ftgrid` can now display embedded bitmap strikes.

Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

- Update from 2.10.4 to 2.11.0
- Update rootfile
- Changelog
CHANGES BETWEEN 2.10.4 and 2.11.0
I. IMPORTANT CHANGES
- A new rendering module has been added to create 8-bit Signed Distance Field (SDF)
bitmaps for both outline and bitmap glyphs. The new rendering mode is called
`FT_RENDER_MODE_SDF`, the pixel mode is `FT_PIXEL_MODE_GRAY8`, and the
corresponding raster flag is `FT_RASTER_FLAG_SDF`. This work was Anuj Verma's
GSoC 2020 project.
- A new, experimental API is now available for surfacing properties of 'COLR' v1
color fonts (as the name says, this is an extension to the 'COLR' table for
outline color fonts using the SFNT container format). 'COLR' v1 fonts are a
recently proposed addition to OFF and OpenType; specification work currently
happens in https://github.com/googlefonts/colr-gradients-spec/ 'COLR' v1 is
expected to be merged to OpenType; the ISO standardisation process for adding
'COLR' v1 as an amendment to OFF is underway. Functions similar to the already
existing 'COLR' API have been added to access the corresponding data.
FT_Get_Color_Glyph_Paint Retrieve the root paint for a given glyph ID.
FT_Get_Paint_Layers Access the layers of a `PaintColrLayers` table.
FT_Get_Colorline_Stops Retrieve the 'color stops' on a color line. As an input,
a color stop iterator gets used, which in turn is retrieved from a paint.
FT_Get_Paint Dereference an `FT_OpaquePaint` object and retrieve the
corresponding `FT_COLR_Paint` object, which contains details on how to draw the
respective 'COLR' v1 `Paint` table.
II. MISCELLANEOUS
- FreeType has moved its infrastructure to https://gitlab.freedesktop.org/freetype
A side effect is that the git repositories are now called `freetype.git` and
`freetype-demos.git`, which by default expand to the directories `freetype` and
`freetype-demos`, respectively. The documentation has been updated accordingly.
FreeType's Savannah repositories will stay; they are now mirrors of the
'freedesktop.org' repositories.
- A new function `FT_Get_Transform` returns the values set by `FT_Set_Transform`.
- A new configuration macro `FT_DEBUG_LOGGING` is available. It provides extended
debugging capabilities for FreeType, for example showing a time stamp or
displaying the component a tracing message comes from. See file `docs/DEBUG` for
more information. This work was Priyesh Kumar's GSoC 2020 project.
- The legacy Type 1 and CFF engines are further demoted due to lack of CFF2
charstring support. You now need to use `FT_Property_Set` to enable them besides
the `T1_CONFIG_OPTION_OLD_ENGINE` and `CFF_CONFIG_OPTION_OLD_ENGINE` options,
respectively.
- The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the auto-hinter
has been removed.
- The smooth rasterizer performance has been improved by >10%. Note that due to
necessary code changes there might be very subtle differences in rendering. They
are not visible by the eye, however.
- PCF bitmap fonts compressed with LZW (these are usually files with the extension
`.pcf.Z`) are now handled correctly.
- Improved Meson build files, including support to build the FreeType demo programs.
- A new demo program `ftsdf` is available to display Signed Distance Fields of
glyphs.
- The `ftlint` demo program has been extended to do more testing of its input. In
particular, it can display horizontal and vertical acutances for quality
assessment, together with computing MD5 checksums of rendered glyphs. [The
acutance measures how sharply the pixel coverage changes at glyph edges. For
monochrome bitmaps, it is always 2.0 in either X or Y direction. For
anti-aliased bitmaps, it depends on the hinting and the shape of a glyph and
might approach or even reach value 2.0 for glyphs like 'I', 'L', '+', '-', or
'=', while it might be lower for glyphs like 'O', 'S', or 'W'.]
- The `ttdebug` demo program didn't show changed point coordinates (bug introduced
in version 2.10.3).
- It is now possible to adjust the axis increment for variable fonts in the
`ftmulti` demo program.
- It is now possible to change the hinting engine in the `ftstring` demo program.
- The graphical demo programs work better now in native color depth on win32 and
x11.

- Update freetype from 2.10.2 to 2.10.4
- A heap buffer overflow has been found in the handling of embedded
PNG bitmaps, introduced in FreeType version 2.6.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999
If you use option FT_CONFIG_OPTION_USE_PNG you should upgrade immediately.
- Version 2.10.3 and later breaks the build of ghostscript, due to ghostscripts
use of a withdrawn freetype macro that wasn't for external usage.
A patch has been created to fix this and is included in the connected
ghostcript patch.
- Updated rootfile
- Changelog for version 2.10.3 release is too long to add here. This can be
found in the changelog file in the tarball
