Haiku R1 Alpha 2 Release Notes

These are the release notes for Haiku R1 Alpha 2.

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 600 MB of drive space.

Known Issues

Subpixel font rendering is disabled by default.

Missing Features

Haiku does not yet support WPA encryption for wireless networking, only WEP encryption is supported.

There is no package management yet.

The Haiku boot manager (bootman) supports a single hard disk drive only.

USB keyboards attached to OHCI or to USB 2.0 hubs do not work in Kernel Debugging Land (KDL). They need to be connected to UHCI root ports to work in KDL. Also note that when entering the kernel debugger by means of a panic it is possible that the keyboard does not work. To work around this issue you can manually enter the kernel debugger once and leave it again to enable the USB keyboard.

Font overlay is not yet implemented in Haiku. As a result, if at the beginning of the installation you choose a language that uses glyphs not supported by the default font (such is the case for Japanese, for instance), the localized text on the screen will become garbled. For such cases, until font overlay is implemented, please run the installer in English mode.

New Features

Haiku's included web browser (WebPositive, powered by WebKit) is not yet a mature web browser.

WiFi via FreeBSD 8 compatibility. Non-distributable firmwares can be installed via A temporary & experimental application setwep can allow WEP based encryption.

Message Signaled Interrupts (MSI) have been implemented. This help to alleviate the lack of proper IRQ routing.

Vastly improved USB mass storage performance through a better page mapping strategy

DriveSetup will now install a basic bootloader when partitioning a disk.

Fixed a network bug that could result in web pages being partially loaded.

Locale kit for providing internationalization in programs.

Translations for User Guide and other system provided documentation.

Numerous speedups, specifically with compilation times.

Many lock contentions have been improved

Numerous code refactoring to kernel/VM subsystems

ACPI is now enabled by default.

Font hinting in FreeType.

The UDF file system module has been fixed

Various vendor software has been updated, most notably bash from 2.x to 4.x

Introduced installoptionalpackage, a rudimentary script to alleviate the lack of a proper package management solution via PackageFS. It allows the installation of some of Haiku's OptionalPackages.

Various POSIX compliance fixes.

API/ABI Changes

  • BJoystick -- fixed a BeOS compatibility issue
  • GCC 4 ABI changes that require applications to be recompiled
  • Introduced library versioning
