Changes for v0.79.120 - v0.79.121
- New detection method added: RESOLUTION_CHANGE (detect_method 8), replaces the unused FUZZY_LOGIC (which is always on). Resolution_change will insert a hard cutpoint when the resolution of a digital recording changes.

Changes for v0.79.103 - v0.79.104
- The default comskip.ini file is not very agressive, I changed the settings to be more agressive. If you start to miss parts of the show revert back to the comskip.ini that is in build 103
- Bug solved: Invoking comskipGUI.exe without any arguments could cause Comskip to crash.
Changes for v0.79.102 - v0.79.103
- Improvements for the for realtime scanning of dvr-ms input, may not work
Changes for v0.79.101 - v0.79.102

Changes for v0.79.98 - v0.79.99
- Changed the Zoomplayer chapter file to use seconds instead of frame numbers to solve alignment problem with digital broadcast
- The default ini file now disables the heuristics as results are too broadcast dependend. Enable with care
- Added the .vdr output format defined by the Linux Video Disk Recorder software and used by XBMC to autoskip commercials. Enable by setting output_vdr=1 in the ini file.
Changes for v0.79.97 - v0.79.98
- Removed the enable_mencoder_pts=1 setting and instead introduced the output_edlp=1 setting enable generating a pts based mencoder file

Changes for v0.79.96 - v0.79.97
- Improved logo recognition
- When enable_mencoder_pts=1 is set in the ini file the generated .EDL file will use the PTS information for the cutpoints to support mencoder. Does ony work for TS files. Running comskip on the .CSV file will always be done as if enable_mencoder_pts=0
