Legend:
 * Changes of existing features or bugfixes.
 + New features.

ObjFW 0.5 -> ObjFW 0.5.1, 21.04.2011
 * Work around a wrong warning produced by Apple GCC 4.0.1 which would cause
   the build to fail due to -Werror.
 * Call objc_thread_{add,remove} when using the GNU runtime to make sure the
   runtime knows about our thread.
 * Detach a thread before restarting if it was never joined.
 * Release the old return value when restarting a thread.

ObjFW 0.4-alpha1 -> 0.5, 09.04.2011
 + %@ is now allowed in format strings.
 + Added of_log for easy logging.
 * Exceptions have one header per exception now.
 * Lots of exception improvements.
 * Huge improvements in XML handling.
 * Improvements in socket handling, including improved API.
 * OFStreamObserver is now thread-safe and stops the current observe call when
   the set of streams to observe is modified.
 + New class OFURL.
 + New class OFHTTPRequest.
 + New class OFCondition.
 * Improvements in objfw-compile.
 + Blocks can be used together with Cocoa now.
 + When linking ObjFW and Cocoa, OFAutoreleasePools are used by both now.
 + Support for Base64.
 + Use a real Xcode project instead of just calling make.
 + Add Haiku to the list of supported platforms.
 * Lots of small bugfixes and countless small changes. Read the commits!

ObjFW 0.3.1 -> 0.4-alpha1, 03.01.2011
 * ObjFW is now available under the terms of the QPL, GPLv2 and GPLv3.
 + Support for blocks was added, including a blocks runtime.
 + Added support for the new GNU runtime, introduced in GCC 4.6.
 * Objects returned from collections are no longer retained and autoreleased.
 + Added new classes OFXMLParser, OFXMLElement, OFXMLAttribute and
   OFXMLElementBuilder.
