* FLV splitter: Recognize ADPCM audio.
* FLV splitter: Recognize Nellymoser audio.
* MPC: Tweaked priorities in DirectShow source filter enumeration. Behavior now better matches that of GraphEdit.
* MPC: Remember active shaders.
* MPC: Added two sharpen shaders.

* MPC: The INITIAL value of the setting "Auto-load subtitles" will now default to OFF when DirectVobSub is detected as installed and to ON when DirectVobSub is not found.
* MPC: Restored the subtitle database functionality and updated it with a working URL.
* MPC: various small changes.

* MPC: Solved a problem with the pixel shader resizer
* MPC: The internal FLV4 video decoder will now only be used in low merit mode.
* MPC: Fixed isdb url.
* FLV splitter: Fixed crash on some files.

* FLV splitter: bugfix

* обновлён до версии rev.40
* устранены мелкие ошибки в программе

* обновлён до версии rev.44
* MPC: Added subtitle delay function for the internal subtitle renderer. It can be controlled with the F1 (decrease delay) and F2 (increase delay) buttons. The default delay interval is 500ms, but can be changed in the options. Patch by MatMaul.
* MPC: Automatically block DirectVobSub filter (VSFilter) when the internal subtitle renderer will be used.
* MPC: (SubResync) Save to .srt subtitle fix concerning italics
* MPC: YUV mixing option is now hidden on Vista (because it does not work on Vista).
* MPC: Added CSS classes in WebInterface.
* MPC: Fixed buffer overrun in VobSub code.
* MPC: Show proper error message when trying to use the "Save Image" function together with Overlay Mixer renderer.

* обновлён до версии rev.49
* MPC: Added some key bindings.
* MPC: Added option to disable the automatic blocking of VSFilter when "Auto-load subtitles" is enabled and the internal subtitle filter is used. Disabling this block allows users to view two different subtitle languages at the same time (if they want to). The option is called "BlockVSFilter" and currently requires manual editing of the registry/ini, since it is not (yet) available in the GUI.

* обновлён до версии rev.53
* Display warning message when a user tries to open a RealMedia file that contains illegal characters in its filename. This will prevent a crash of the Real engine.
* Updated libpng
* FIXED: Access violation using VSFilter as AviSynth plugin

* обновлён до версии rev.55
* Added revision number to About dialog

* обновлён до версии rev.72
* MPEG Audio Decoder: Updated liba52
* MPEG Audio Decoder: Updated libdts
* VSFilter: Added RealText support
* VSFilter: Fix rare seeking issue with VobSubs
* VSFilter: Fix potential jitter issues with \pos overrides in VSFilter.
* VSFilter: Really fix two subtitle rasterisation bugs: Go back to old pixmix/pixmix2 architecture originally used in Subtitler and early versions of VSFilter, implement an SSE2 version of pixmix2 and ensure (widened-region minus fill) math doesn't underflow. Completely fixes "\be1 stray dots" and "vector \clip kills alpha" bugs.
Also add several comments explaining the rasterisation code.
* VSFilter: Add support for variable strength and animated \be, and implement gaussian \blur as an alternative. (\blur also does edge blur like \be but in a nicer way.)
* VSFilter: Add new override tags \xbord \ybord \xshad \yshad to control border and shadow size separately in X and Y directions.
* VSFilter: Add "inverse clip" tag \iclip to specify what to hide rather than what to show.
* VSFilter: Partial workaround for problem where border colour shows through fill colour during \fad and \fade fades. This workaround potentially causes small seams to be visible during the fade, unfortunately this is the price to pay for getting correct fades.

* обновлён до версии rev.78
* A little shuffling around of the blur-handling code
* Enable whole-program optimisation in Release Unicode builds of VSFilter, might be the cause of performance issues some people report.
* VSFilter: Fix freeze that occurred with the combination MPC + VSFilter + Haali Video Renderer.
* MPC: Fixed playlist shuffle functionality

* обновлён до версии rev.82
* Добавлена возможность сохранения изображения в PNG формат
* Обновлена библиотека libpng до версии 1.2.32
