     1HAIKU R1 Alpha 5 Release Notes
     2
     3These are the release notes for HAIKU R1 Alpha 5. For this fifth 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.
     4
     5We 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.
     6
     7Another goal that has driven the release of the Alpha 5 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.
     8
     9System Requirements
     10
     11Haiku 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.
     12New Features
     13
     14This 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.
     15
     16Wireless networking now supports WPA/WPA2. (See "Workshop: Wireless networking" in the HAIKU User Guide)
     17
     18Various 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
     19
     20Added pcnet network driver, which eases the use of VirtualBox to run Haiku
     21
     22Additional 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
     23
     24Updated WebKit, which improves rendering in the native browser WebPositive
     25
     26StackAndTile, a method for managing multiple windows, has been improved (OPT + first mouse button to activate stacking and tiling of adjacent windows)
     27
     28IPv6 modules added
     29
     30The BFS file system is more robust and has new tools for detecting and correcting issues
     31
     32Support for very large disks and partitions (greater than 63 TB)
     33
     34Improved virtual memory settings and swap file creation logic
     35
     36Additional KDL debugging tools, including the ability to generate QR codes from the debug output
     37
     38Numerous potential memory leaks fixed
     39
     40Expanded the POSIX signal support with real-time extensions
     41
     42Update of the secondary and experimental compiler to GCC 4.6.3 (available via setgcc gcc4)
     43
     44Update of OpenGL kit to newer Mesa3D 7.8.2
     45Missing Features
     46
     47Package management is still being developed and is not included in this release. For the time being, a temporary script is included to help install a small set software (available via installoptionalpackage).
     48Known Issues
     49
     50LiveCD and first boot performance: After an initial installation or a boot into LiveCD mode, some background tasks are executed to finish the installation setup. This is known to degrade performance. On hard disk installs this usually is not a problem as the tasks are done quickly. In LiveCD mode the performance hit is more prominently visible due to the usually bad seek performance on CDs. Since the CD is read-only, this setup takes place on every start of the LiveCD. On writable media it will only be done once, so further boots shouldn't experience the same delays.
     51
     52Font rendering, while improved due to the expired font hinting patent, is still not optimal. Due to the uncertain situation about patents, the official release has disabled code, which is known to be patented. This sadly includes the subpixel code used by FreeType. Once the situation is better understood and a decision has been made, subpixel font rendering may get re-enabled for official releases.
     53
     54Haiku's ACPI support, which is enabled by default, might cause problems on some hardware. ACPI can be disabled in the boot loader's safe mode options menu.
     55
     56Copying large amounts of data from faster to slower disk drives (like USB sticks) can cause the system to start paging.
     57
     58The Haiku boot loader has been reported to hang on some hardware.
     59
     60Support for localization/internationalization is still a work in progress. Some applications might only be partially translated and have issues with long strings in languages other than English.
     61
     62Firmware for some wireless network cards need user acknowledgement, prior to their installation. This includes Broadcom 43xx, Intel ipw2100, Intel ipw2200 and Marvell 88W8335. As a temporary measure, a script is included to assist in this process (available via install-wifi-firmwares.sh).
     63
     64Some Marvell Yukon cards are known to have low network performance.
     65
     66The IMAP protocol for the mail daemon replacement (MDR) has been removed from this release, due to concerns of losing server side data.
     67
     68Due to size constraints of CDs, several developer related tools have been removed (e.g., hg, svn, cvs, python. They can be installed via installoptionalpackage)
     69Source Code
     70
     71The source code of Haiku itself, the source code of the required build tools and the optional packages (except for closed source ones) is made available for download at: ​http://www.haiku-files.org/files/releases/r1alpha4/sources/
     72Reporting Issues
     73
     74There are over 2400 open tickets on Haiku's bug tracker and over 6600 closed items. If you find what you believe to be an issue, please search our Trac to see if it has already been reported, and if not, file a new ticket: ​http://dev.haiku-os.org/
