    * New DDF driver for the Intel PCI bus controller.
    * New DDF driver for the ns8250 serial port.

+ * Minimalistic support for ATAPI CD-ROM in ```ata_bd```.

  * FAT file system server
    * Sequential file I/O has linear time complexity in number of blocks for most use patterns. Previously, time complexity of sequential I/O was always quadratic in number of blocks.
+ * DEVFS was improved to handle recursive requests better.
+ * VFS now supports file systems that wish to serialize I/O on files themselves.
+ * VFS uses async framework sessions to allow making parallel requests to endpoint file systems.
+ * VFS now maintains per-client tables of open files as compared to per-connection tables.

  * The dp8390 NIC driver has been almost entirely rewritten.
  * The ARP module will now wait for answer to each request it sends so that e.g. the first ping will not time out.
+ * The TCP module got some fixes, but is still not working as expected.

  * Languages
    * Added ```sbi``` interpreter of the [wiki:Sysel] experimental programming language.
+ * ```klog``` writes its output also to /log/klog.
+ * Task termination
+   * Added ```kill``` command to kill a specific task by its task ID.
+   * Added ```killall``` command to kill all tasks of the given name.
+ * Added simple ```sysinfo``` command to allow basic sysinfo tree inspection from user interface.

    * Robustness
      * The standard library will detect and report programming errors such as certain types of deadlocks,  improper mixing of serialization means, and when locks are not being held as necessary.
+   * Concurrency
+     * Added the concept of sessions to the async framework, giving async framework clients a standard means of making parallel requests.
+     * The VFS client code was rewritten to make use of the async framework sessions.
  * Added ```clui``` library to be used by applications with some form of text input.
    * CLUI-based applications can be terminated by pressing Ctrl-Q when waiting for text input.

    * It is now possible to do a barebone build in which only essential binaries are included.
    * Support for GCC 4.5+ link-time optimizations.
