* New audio waveform/spectrogram display.
* Added option for preserving empty frames during recompression or decompression instead of replicating frames.
* Added option for saving raw audio stream without a header.
* Added support for the Sony WAVE64 file format, for wave files larger than 4GB.
* Added support for reading and writing Adobe Filmstrip (.flm) files.
* Added support for reading Maya IFF (.iff) files. Currently this is limited to RGB information at 8 bits/channel.
* PNG output is now supported.
* Resize video filter now has options for relative and aspect-ratio derived sizing and to save defaults.
* Opening a video file from the command-line or drag-and-drop now sets the filename as default for the Save As AVI/WAV dialogs.
* Added new pitch scaling audio filter.

* AVIs with MP3 audio streams where wBitsPerSample != 0 are now detected and auto-corrected for better compatibility with the standard MP3 codec installed in Windows.
* Rewrote segmentation code to buffer data instead of attempting size prediction; this makes the segmentation more accurate and avoids dangling key frames during on-the-fly compression.
* Added workaround for compatibility problems with Aero Glass in Windows Vista beta 2.
* Audio displacement now works when processing only part of the audio stream.
* Added warning for non-zero dwStart values in AVI files.
* Fixed a performance problem in the PNG decoder on large images with a lot of IHDR blocks.
* Fixed errors in JPEG encoding with pure red or blue colors.
* Changed keyboard shortcut for Undo from Ctrl+U to the standard Ctrl+Z.

* Improved support for working with video codecs that are configured to only output YUV formats.
* Added more checks to script parameters for "resize" video filter.
* Fixed gradient bugs in "smoother" video filter.

What's new in this version:
[features added]

* There is now an option to avoid tearing in the video display panes.
* Script: Added VirtualDub.Exit(int) command to end the program with a specific error code.
* Script: Added VirtualDub.subset.length property for current length of subset in frames (timeline).
* Script: Added VirtualDub.video.length property for current length of source video in frames.
* Capture: The list of statistics displayed in the info panel has been expanded and can be filtered from the Preferences dialog.
* Capture: Modified option to adjust video timing based on drift from ideal stream timing rather than real-time.
* Capture: Reworked video timing interpolation to be less sensitive to discontinuities in the system timer.
* Capture: "Autoincrement filename" option now automatically skips over existing files as well.
* Capture: Added timing graph to visualize behavior of resync engine.
* Capture: Timing logs, if enabled, are automatically saved at the end of capture.

* Capture: Backspace now works when entering channel numbers.
[bugs fixed]
* Increased precision of processing fps estimate.
* "Space" is no longer listed as an accelerator for "abort dub" since it doesn't work as such when rendering to disk. It still works for preview.
* Fixed job control re-enabling itself if a menu command is chosen while a job is running, leading to possible reentrancy crashes.
* Clearing the current job list or loading a new one while a job was in progress led to a crash.
* Invalid MPEG-1 layer II frame headers display a slightly less confusing error than "internal error."
* Renamed "use internal MJPEG decoder" in AVI extended open options to "use internal decoders," since it happened to force the internal DV decoder too. Added a sticky option in Preferences for this.
* Filters were receiving inconsistent output frame numbers when using input preview or saving with a starting offset.
* Fixed crash when crop rectangle reduced filter input to smaller than 1x1.
* Fixed crash when using deinterlace filter in "duplicate field 2" mode.
* Fixed broken cropping in some modes of deinterlace filter.

* CLI tool didn't work properly when path to vdub.exe/vdub64.exe contained spaces.
* Removed some hard-coded limits on frame rates in the Frame Rate dialog box.
* Fixed minor memory leak when plugins fail to load.
* Fixed a case where an I/O error on the output AVI file could cause a hang instead of an error to be displayed.
* MPEG-1: Fixed yet another rare frame decoding error when seeking randomly in the timeline.
* MPEG-1: Fixed crash when opening file with all CPU optimizations forced on.
* D3DFX: vd_tvpcorrect, vd_t2vpcorrect, vd_tvpcorrect2, and vd_t2vpcorrect2 constants were computed with U and V sizes swapped.
* Capture: VFW devices sometimes didn't display overlay properly with full-height frame sizes and consumed additional CPU due to the preview hook being left enabled.
* Capture: The Video File (emulation) test capture driver is no longer a candidate for being saved as the driver to auto-start the next time capture mode is entered.
* Capture: Unicode filenames are now displayed properly in the title bar.
* Capture: Fixed 0.03%% sync error when using NTSC frame rates.
* Capture: Fixed random crash when modifying filter parameters with a WDM capture driver active in accelerated preview mode.
* Capture: Fixed keyboard focus on startup so that entering channel numbers works again.

What's new in this version:
[bugs fixed]
* Fixed occasional crash if display panes are refreshed while editing the filter list.
* Fixed hang if VirtualDub is the active application and attempts to refresh the display panes when a display mode switch occurs.
* Display panes did not always update properly when seeking if Direct3D mode was enabled and updating the frame took a lot of CPU time.
* Direct3D display mode could be activated if checked even if the option was grayed due to DirectX support being disabled.
* Capture: Fixed crash if capture is attempted with audio enabled but audio isn't present or is in an incompatible format.
* Reversed direction of mouse wheel action to be consistent with Windows.
* Hex editor's Extract Segment command would sometimes extract the wrong segment due to repainting the main pane during the extract.
* CLI interface app didn't exit if console was empty prior to invocation due to overzealous Explorer detection. This is now only done if no arguments are supplied.
* Fixed crash in MPEG-1 parser when encountering a pack with a too-short length, such as zero.
* Audio codec errors sometimes reported the wrong source of the error (i.e. decompressor vs. compressor).
[regressions fixed]
* Pixel shaders were disabled in Direct3D bicubic mode due to debug code mistakenly left in.
* MRU list sometimes didn't resort properly when reopening a recently opened file.

What's new in this version:
[features added]
* Script: Added support for cast expressions to int/long/double.

[bugs fixed]
* Fixed crash when decoding audio from broken or mismatched DV frame.
* Hierarchical AVI index blocks were being placed outside of RIFF chunks. No known actual incompatibility cases (yet).
* Fixed occasional crash when using lowpass or highpass filters with a large tap count.
* Fixed crash on attempting to abort a render when an error had already occurred.
* Fixed "cut off audio stream when video stream ends" sometimes being active even after being disabled.
* Fixed audio stream being shortened slightly when using audio compression.
* Capture: Fixed crash in volume meter code triggered by load of DLLs that whack the floating-point control word.
* Capture: Fixed crash on exit in DirectShow layer caused by shutting down COM too early.
[regressions fixed]
* Script: Fixed "method not found" errors loading .vcfs caused by failure to convert longs to ints.
