FreeType is a freely available software library to render fonts.
It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats.
Some products that use FreeType for rendering fonts on screen or on paper, either exclusively or partially:
Counting the above products only, you get more than a billion devices that contain FreeType.
Besides various maintenance fixes, this release comes with support of WOFF 2 fonts. More details are listed in the list of changes.
A new maintenance release, fixing bytecode hinting of OpenType variation fonts and cmap processing of PCF fonts, among other things. Check the list of changes for more fixes.
This release brings one notable feature, namely support for color-layered outline glyphs (for example, scalable emoji glyphs). Additionally, the API reference has been completely overhauled and modernized, as already announced.
As usual, many minor fixes and corrections have been applied also; a detailed list is given here.
A revamped version of the FreeType website is available for preview here. It includes a complete interface redesign, and uses markdown as input which greatly improves maintainability. Comments are welcome.
This is a maintenance release; most importantly fixing correct handling of Type 1 fonts with flex features, which was broken in version 2.9. An overview of the remaining changes is given here. All users should upgrade.
FreeType version 2.9, the first release of a new ‘minor’ series, is now available for download. The main reason for starting a new series is Ewald Hew's GSoC contribution of making Adobe's CFF engine handle Type 1 fonts also, greatly improving the rendering quality of this ancient but still important font format.
If you are going to use variation fonts, please update to this version since it comes with some important fixes. More information on this and other changes can be found here.
FreeType 2.8.1 has been released. This is mainly a maintenance release with one important change: By default, FreeType now offers high quality LCD-optimized output without resorting to ClearType techniques of resolution tripling and filtering. In this method, called Harmony, each color channel is generated separately after shifting the glyph outline, capitalizing on the fact that the color grids on LCD panels are shifted by a third of a pixel. This output is indistinguishable from ClearType with a light 3-tap filter.
See here for a extensive list of changes; noteworthy bug fixes are correct handling of B/W TrueType hinting and some OpenType variation font handling issues.
FreeType 2.8 has been released. CFF2 support and OpenType variation font handling is now complete; the auto-hinter now understands 25 more scripts, for example N'Ko and Tifinagh.
See here for a list of changes; noteworthy bug fixes are the handling of TrueType fonts: unhinted loading didn't work as expected, and the light auto-hinter used incorrect metrics.
The FreeType project was accepted to be part of Google Summer of Code 2017! Here's a link to our ideas list – if you have another one, please write to our mailing list so that we can discuss your suggestions, eventually adding them to the list. And if you want to participate as a student, now is the time to discuss everything, again using the mailing list.
FreeType 2.7.1 has been released. The most important news is preliminary support of Adobe's new CFF2 font format and variation fonts as specified in the new OpenType specification version 1.8. It also fixes the handling of raw CID fonts (which might be found in PDF files)
See here for a list of changes.
We start a new ‘minor’ series, which finally allows us to activate a new default mode for bytecode hinting (see also the announcements below for version 2.6.4 and 2.6.5): Subpixel hinting, also known as ClearType hinting.
In case you are already using subpixel hinting (for
example, by using the ‘Infinality patches’ as
provided by some GNU/Linux or BSD distributions, or
directly
from bohoomil.com),
be noted that the new mode might provide subtle
differences; the code was simplified to make
it much faster. If you are used to the old
full-pixel hinting, you will see many rendering changes.
If you really dislike them, you can disable them at
compile time or using the
new FREETYPE_PROPERTIES environment
variable.
A description of the remaining changes can be found here, as usual.
This release is almost identical to the previous version, with two differences.
FreeType 2.6.4 has been released. The most important change is a new bytecode hinting mode for TrueType fonts that finally activates subpixel hinting (a.k.a. ClearType hinting) by default.
The new release also brings support for the following new scripts in the auto-hinter: Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi, Malayalam, Sinhala, and Tamil.
See here for a detailed list of changes.
FreeType 2.6.3 has been released. It brings support for four new Asian scripts in the auto-hinter (Khmer, Myanmar, Kannada, and Bengali), together with other, minor improvements and bug fixes.
See here for a detailed list of changes.
FreeType 2.6.2 ships with three interesting details for users and developers of rendering libraries that deal with text. Read more.
FreeType 2.6.2 has been released. This is a minor release that mainly provides better handling of malformed fonts. All users should upgrade.
A new feature is stem darkening support for the auto-hinter. Note, however, that it is off by default, since most graphic systems don't provide correct linear alpha blending with gamma correction, which is crucial for a good appearance. For the same reason, stem darkening for the CFF engine is now off by default, too.
See here for a more detailed list of changes.
FreeType 2.6.1 has been released. This is a minor release that corrects problems with CFF metrics, and that provides better handling of malformed fonts. Two notably new features are auto-hinting support for the Lao script and a simple interface for accessing named instances in GX TrueType variation fonts.
See here for a list of changes.
FreeType 2.6 has been released. This is a new major release that provides a better (and simpler) thread-safety model. Among other new features we now have auto-hinting support for Arabic and Thai, together with much improved handling of Apple's GX TrueType variation font format.
See here for a list of changes.
Besides user support and fixing bugs, your money will help me implement the following issues.
FreeType 2.5.3 has been released. All users should upgrade due to fixed vulnerability in the CFF driver (CVE-2014-2240).
Its main new feature is much enhanced support of auto-hinting SFNT fonts (i.e., TrueType and CFF fonts) due to the use of the HarfBuzz library. A more detailed description of this and other changes can be found here.
FreeType 2.5.2 has been released. It fixes a serious bug introduced in version 2.5.1; all users should upgrade.
A listing of the changes can be found here.
FreeType 2.5.1 has been released, providing three major new features.
Among other changes I want to mention that FreeType's TrueType debugger (ttdebug) has been made more versatile. An exhaustive list of changes can be found here.
Thanks to a very generous donation by Pierre Arnaud from Epsitec, the pledgie campaign for FreeType has reached its goal. I want to say thank you again to all donors! Of course, noone stops you from further donating to the campaign :-)
After integration of Adobe's CFF module and Google's color emoji support, I will use the next months to work on the remaining issues that I've promised to implement. Stay tuned!
FreeType 2.5 has been released. A major new feature is support for color embedded bitmaps (eg. color emoji), contributed by Behdad Esfahbod on behalf of Google. Additionally, Adobe's CFF engine is now the default, which makes a good reason to change from the 2.4.x to the 2.5.x series.
On the technical side, the property API to access FreeType module parameters (FT_Property_Set and FT_Property_Get) is now declared as stable.
As usual, see this file for the complete release notes, which give more details. And we have again blog entries from Adobe and Google.
