wiki:R1/Beta3/ReleaseNotes

The third beta release of Haiku continues the trend of more frequent releases in order to provide our users and developers with an up to date and stable platform to work on.

Please keep in mind that this is beta-quality software, which means it is feature complete but still contains known and unknown bugs. While we are mostly confident in its stability, we cannot provide assurances against data loss.

System requirements

This release is available on the x86 32-bit platform, as well as the x86_64 platform. Note that BeOS R5 compatibility is only provided on the 32-bit images, but the 64bit version is recommended if you don't need BeOS compatibility.

MINIMUM (32-bit)

  • Processor: Intel Pentium II; AMD Athlon
  • Memory: 384MB
  • Monitor: 800x600
  • Storage: 2GB

RECOMMENDED (64-bit)

  • Processor: Intel Core i3; AMD Phenom II
  • Memory: 2GB
  • Monitor: 1366x768
  • Storage: 16GB

SSE2 support is required to use the WebPositive web browser. On machines where this is not available, it is recommended to install the NetSurf browser instead.

Highlights

  • It's possible to use Installer to cleanly reset an existing system by installing over it.
  • It's possible to go back to FirstBootPrompt from Installer if you change your mind and want to use live mode.
  • Improvements to DriveSetup GUI and backend to make disk partitioning easier and more reliable.

Package management

  • The system update can now resume downloads in case it is interrupted.
  • Support for running a script on package uninstall
  • Performance improvements for package icons handling in HaikuDepot
  • Numerous stability and user improvements to HaikuDepot
  • Deprecated Python 2 and switched to Python 3.7 as the default version of Python shipped with Haiku

User interface

  • Implement center and right-aligned BTextView support and various fixes to BTextControl for better handling of cursor movements.
  • Improved support for dark color scheme
  • Integration of PadBlocker in Input preferences (disable touchpad when keyboard is used)
  • Scale scroll bars according to UI/font size
  • Several changes to make localization better
  • Support of CPUs with more than 8 cores in ProcessController load graphs
  • Display CPU manufacturer logo in Pulse
  • Numerous stability and compatibility improvements to MediaPlayer
  • The application icon in the shutdown dialog is animated when the application does not want to close

app_server (graphics server)

  • Various fixes for clipping and flickering problems in app_server
  • Support for more composite drawing operations (used in the web browser for javascript canvas support)
  • Fixed the font overlay/fallback system and added an extra font to it (Noto Sans Symbols 2)
  • Reworked memory management and fixed some memory corruption bugs

Web browser

  • Accept-Language header was missing, breaking some websites
  • A dark "Document Color" system theme color triggers "dark mode" on websites
  • "Search the web" context menu works again
  • Easy selection of default search engine from a list of common ones
  • Search shortcuts, for example typing "w Haiku" in the address bar will open the Wikipedia article about Haiku.
  • WebKit engine (haikuwebkit) upgraded to WebKit 612.1.21

APIs

  • Introduced a new version of the "net services" APIs (http and gopher clients). It is moved to a static library, allowing us to make changes without breaking applications. Existing applications can continue to use the old API (present until beta2) but that will be removed later. It is recommended to adjust and recompile such applications before the next Haiku release.

  • Fixed pselect interaction with signals
  • Fixed the return code of fsync when called on fifo pipes

  • Added exp10, exp10f and exp10l to math.h (only in _GNU_SOURCE)
  • Fixed behavior of write() in O_APPEND mode
  • Implemented posix_fallocate
  • Added ut_host in utmpx.h
  • Added ppoll()
  • Implemented a missing escape sequence in terminal to insert repeated characters

  • Optimize BMenuItem::RemoveItem to be O(1) instead of O(n)
  • Improvements on cpufreq management
  • Improve caching in MediaPlayer to allow playing 4K video
