Overview of changes leading to 2.8.1
Tuesday, May 4, 2021
====================================
- Subsetter now fully supports GSUB/GPOS/GDEF tables (including variations); as
such, layout tables are retained by subsetter by default. (Garret Rieger, Qunxin Liu)
- Build scripts no longer check for FontConfig as HarfBuzz does not use it.
- hb-view supports iTerm2 and kitty inline image protocols (Khaled Hosny),
it can also use Chafa for terminal graphics if available (Hans Petter Jansson).
Overview of changes leading to 2.8.0
Tuesday, March 16, 2021
====================================
- Shape joining scripts other than Arabic/Syriac using the Universal Shaping Engine.
Previously these were shaped using the generalized Arabic shaper. (David Corbett)
- Fix regression in shaping of U+0B55 ORIYA SIGN OVERLINE. (David Corbett)
- Update language tags. (David Corbett)
- Variations: reduce error: do not round each interpolated delta. (Just van Rossum)
- Documentation improvements. (Khaled Hosny, Nathan Willis)
- Subsetter improvements: subsets most, if not all, lookup types now. (Garret Rieger, Qunxin Liu)
- Fuzzer-found fixes and other improvements when memory failures happen. (Behdad)
- Removed most atomic implementations now that we have C++11 atomic impl. (Behdad)
- General codebase upkeep; using more C++11 features: constexpr constructors, etc. (Behdad)
Overview of changes leading to 2.7.4
Sunday, December 27, 2020
====================================
- Fix missing --enable-introspection configure option from previous release
tarball.
- Documentation updates.
Overview of changes leading to 2.7.3
Wednesday, December 23, 2020
====================================
- Update USE shaper to 2020-08-13 specification, and other improvements.
- Don’t disable liga feature in myanmar shaper, to match Uniscribe.
- Improvements to language and script tags handling.
- Update language system tag registry to OpenType 1.8.4
- Support for serializing and deserializing Unicode buffers. Serialized buffers
are now delimited with `<>` or `[]` based on whether it is a Unicode or
glyphs buffer.
- Increase buffer work limits to handle fonts with many complex lookups.
- Handle more shaping operations in trace output.
- Memory access fixes.
- More OOM fixes.
- Improved documentation.
- Build system improvements.
- New API:
+hb_buffer_has_positions()
+hb_buffer_serialize()
+hb_buffer_serialize_unicode()
+hb_buffer_deserialize_unicode()

You want to follow the 32bit instructions. The 64bit equivalents are included
for reference.
1. Install Wine from your favorite package manager. On Fedora that's `dnf install wine`.

- Fedora: `dnf install wine`.
2. And `mingw-w64` compiler.
With `brew` on macOS, you can have it like `brew install mingw-w64`.
On Fedora, with `dnf install mingw32-gcc-c++`, or `dnf install mingw64-gcc-c++` for the
64-bit Windows. Use `apt install g++-mingw-w64` on Debian.

- Mac: `brew install mingw-w64`
3. See how `.ci/build-win32.sh` uses meson or run that script anyway.
3. If you have drank the `meson` koolaid, look at `.ci/build-win32.sh` to see how to
invoke `meson` now, or just run that script. Otherwise, here's how to use the
old trusty autotools instead:
a) Install dependencies.
- Fedora, 32bit: `dnf install mingw32-glib2 mingw32-cairo mingw32-freetype`
- Fedora, 64bit: `dnf install mingw64-glib2 mingw64-cairo mingw64-freetype`
b) Configure:
- `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild`
- 32bit: `../mingw-configure.sh i686`
- 64bit: `../mingw-configure.sh x86_64`
Now you can use `hb-shape` by `(cd win32build/util && wine hb-shape.exe)`
but if you like to shape with the Microsoft Uniscribe:
