-------------------------------------------------------------------------------- Release Date | Version | Details -------------------------------------------------------------------------------- 06/05/93 | 1.00 | Initial release | | 26/05/93 | 1.01 | Bug fixes: | | | | * Crashed on 386+ machine if EMM386.EXE or | | equivalent loaded with NOEMS option. No VCPI | | detected unless EMMXXXX0 device driver available. | | 10/08/93 | 1.02 | Bug fixes: | | Internal | | * PCX format output incorrectly duplicated the Release | | last pixel in a scan line. Only | | * Included missing 'Activation Timed Out' message | | for Last Error (caused by DOS in permanently | | busy state). | | * Corrected error in horizontal pixel pan handler | | for 256-colour modes. | | * Changed method of calculating 64K video RAM | | segment wrap versus paged memory access. | | This was not a reported bug, as yet. With luck no | | further bugs have been introduced by this. | | | | Enhancements: | | | | * Added /CLICKS switch at user request. | | * Added extra interrupt 21h trap to avoid excessive | | DOS busy timeout delays during intensive disk use. | | * Implemented split screen and pixel pan handler for | | the non-standard 256-colour mode using 4-plane | | non-chained (interleaved) memory mapping. | | * Base VGA detection (regardless of SuperVGA tests) | | now overruled by the /V:VGA switch. This allows | | the user to load SCREEN Thief regardless of video | | card type and should be used with due caution. | | * Added 24-bit support for PCX and BMP formats. | | * Added RLE compression for 16 and 256 colour BMPs. | | * Improved BMP creation method. Faster, less noisy. | | * Added /RGB switch for quick x3 Max Width setting. | | * Added /STREAMSIZE switch. | | 20/08/93 | 1.10 | Bug fixes: | | Internal | | * Non-blinking pixels in 16-colour graphics mode are Release | | now correctly interpreted with an intense attribute. Only | | | | Enhancements: | | | | * Added support for CIRRUS LOGIC CL-GD5422 chip. | | Fully tested including HiColor and TrueColor modes. | | * Added TXT, ASC and SCR Output Formats. | | * Expanded TIFF support for 2, 4, 16 and 256 colours. | | * Implemented more exact emulation of the VGA CRT | | Controller. Now even ridiculous settings such as | | a non-zero Preset Row Scan value (vertical panning) | | under graphics modes are simulated. | | * Added /BLINKATTR switch. | | * Added support for OAK 037C/057/067/077 chip sets. | | * Improved command line syntax error reporting. | | * ST now only clears screen when run if already in | | colour text mode. before it always reset the mode, | | causing the display to flash on some adapters. | | * Added PgUp, PgDn and first character jump for | | scrolling help window list. | | * Status screen updated to include most options. | | * Added /FULLFRAME switch. | | 26/09/93 | 1.50 | Enhancements: | | | | * Implemented LZW compression within TIFF format. | | 07/12/93 | 1.55 | Bug fixes: | | Limited | | * GIF, TXT, ASC and SCR outputs now correctly Release | | ignore the /RGB switch setting as these do Only | | do not support 24-bit output and the surplus | | allocation is simply a waste of memory. | | | | Enhancements: | | | | * Substantial changes made to the GIF encoding | | algorithm. Linked list code searches rather than | | table searches provide for a greatly improved | | performance when capturing screens with many, | | varied colours. Tests have shown improvements | | of up to 1000% with 256-colour photo images | | (e.g. 7 seconds not 70!). The down side is an | | up to 100% increase in capture time for images | | with few colours or colour changes (e.g. from 3 | | seconds up to 6 seconds) and a 33% increase in | | memory usage (GIF encoding table entries are now | | 4-byte, not 3-byte). The advantages out-weigh the | | disadvantages. | | 07/03/94 | 1.56 | Bug fixes: | | | | * Cured significant bug in the video buffer control | | logic which caused occasional image corruptions | | when capturing games using scrolling effects. | | * Removed nasty bug introduced with v1.50 where | | CGA 2 colour mode caused immediate hang. | | * PCX format now correctly sets palette type as 1 | | for 24-bit images. | | * Modified BMP output so that palette information | | length matches biClrUsed field in all cases. | | | | Enhancements: | | | | * Added support for Tseng ET4000 chip set. Fully | | tested other than 32K/64K colour modes. | | * Added support for S3 86c911 chip set. Fully | | tested including 640x480x32K mode. | | * Cosmetic changes. Trailing backslash removed from | | the directory entry on the status screen. Setting | | directory back to current using single dot name | | is recognised and redisplays . | | * Added CONFIG.ST file support. | | 15/08/94 | 1.57 | Bug Fixes: | | | | * Cured problem with DOS version tests under | | OS/2 2.x | | * Fixed problem with BMP output format which caused | | hanging or invalid image files. | | 25/10/94 | 1.58 | Bug Fixes: | | | | * Cured incorrect Numeric Naming which started | | from 00000101 instead of 00000001. | | * Fixed occasional problem in naming technique | | which resulted in a File Creation Failed error. | | --------------------------------------------------------------------------------
