HAIKU R1 Alpha 4.1 Release Notes

These are the release notes for HAIKU R1 Alpha 4.1, a critical bugfix update for our fourth official release. For this fourth alpha release, we strove to provide an improved version of Haiku that is more stable, introduces more features for both the end-user and developer, and has a greater chance of properly booting on more hardware.

We have tried hard to make this release as good as possible. Still there are a few known issues and missing features, some of them collected below. Please keep in mind that this is alpha software, which means it is not yet feature complete and still contains known and unknown bugs. While we are mostly confident in the stability of this release, we do not provide any assurances against data loss.

Another goal that has driven the release of the Alpha 4 was to provide current and future Haiku developers an updated and (mostly) stable operating system to work on their software projects. Therefore we have included the basic build tools. This release of Haiku is capable of building and running binaries using either GCC 2 or GCC 4. The use of GCC 4 is discouraged however if not absolutely necessary, as no API compatibility is guaranteed with future versions of Haiku.

Due to the immediate testing efforts of Release 1 Alpha 4, we are able to release this critical bugfix version. The specific bugs fixed in this point release are http://dev.haiku-os.org/ticket/8684, http://dev.haiku-os.org/ticket/9128, and http://dev.haiku-os.org/ticket/9148. These issues prevented Haiku from booting properly on several hardware configurations.

Thank you all who reported the issues on the bug tracker and we appreciate your understanding. 

System Requirements

Haiku currently only works on x86 systems. Minimum memory required is 128 MB. If compiling Haiku within itself, 1 GB of memory is recommended. Haiku has been tested to work on CPUs as slow as a Pentium II 400 MHz, and requires as little as 700 MB of drive space.

New Features

This is a glimpse into some of the more notable improvements and additions to Haiku, since the previous release, R1 Alpha 3. It should be noted that over 1000 bugs closed as fixed since R1 Alpha 3. Additionally, more than 100 subtle bugs have been fixed, which were discovered by Coverity.

  • Wireless networking now supports WPA/WPA2. (See "Workshop: Wireless networking" in the HAIKU User Guide)
  • Various enhancements for hardware support, such as video drivers (radeon hd, intel extreme), network drivers, OHCI USB, PS/2, initial Blu-ray Disc (UDF 2.50), Sandy Bridge CPUs, and better AMD/Intel CPU name detection
  • Added pcnet network driver, which eases the use of VirtualBox to run Haiku
  • Additional applications include a native debugger application (Debugger), a utility for assisting users of multiple keymaps (KeymapSwitcher), a 10 channel equalizer media add-on, and a new GLife screensaver donated by Aaron Hill
  • Updated WebKit, which improves rendering in the native browser WebPositive
  • StackAndTile, a method for managing multiple windows, has been improved (OPT + first mouse button to activate stacking and tiling of adjacent windows)
  • IPv6 modules added
  • The BFS file system is more robust
