* Installation Changes in Emacs 29.1
** Emacs has been ported to the Haiku operating system.
The configuration process should automatically detect and build for Haiku.
There is also an optional window-system port to Haiku, which can be enabled
by configuring Emacs with the option '--with-be-app', which will require
the Haiku Application Kit development headers and a C++ compiler to be present
on your system. If Emacs is not built with the option '--with-be-app', the
resulting Emacs will only run in text-mode terminals.
** FreeType and HarfBuzz support has been ported to the Haiku operating system.
To enable FreeType support, ensure that the FreeType development
headers are present on your system, and configure Emacs with
'--with-be-freetype'. If Emacs is not configured for FreeType, the
default font driver that will be enabled which will not have HarfBuzz
support.
+++
** Cairo drawing support has been enabled for Haiku builds.
To enable Cairo support, ensure that the Cairo and FreeType development files
are present on your system, and configure Emacs with '--with-be-cairo'.
---
** Double buffering is now enabled on the Haiku operating system.
Unlike X, there is no compile-time option to enable or disable double-buffering.
If you wish to disable double-buffering, change the frame parameter
`inhibit-double-buffering' instead.
