- WHATSNEW.DOC December 1990
-
-
- This documents the user visible changes to ARJ from previous versions.
-
-
- ARJ 0.20
-
- ***IMPORTANT CHANGES***************************************************
-
- The problem of an update to an ARJ archive including itself in the
- add has been resolved. Because of the fix, you can no longer "a",
- "f", "m", "u" to a wildnamed archive. ARJ a *.ARJ *.C is not valid
- anymore. This also fixes the problem of a move command sometimes
- deleting the archive itself.
-
- For users of RAW.COM (raw console mode), ARJ now has a "-jc" switch
- to check for RAW mode and to switch to cgets() instead of fgets()
- which hangs in RAW mode. This switch may become the default if it
- proves stable.
-
- The "-x" switch is changed. It now is used as the exclude selected
- filenames switch. The create self-Extractor switch is now "-je".
-
- The "-d"elete switch has been changed so that ARJ will prompt for
- permission to delete the successfully added files. You can
- disable the prompt with the "-y" switch or you can use the "m"ove
- command instead.
-
- The "-s" switch will work with non-update commands now like "l".
-
- ARJ now supports the use of either "-" or "/" as the switch option
- character. The first occurrence of either "-" or "/" that ARJ
- encounters will determine the switch symbol. You may not mix and
- match switch symbols. This also includes the ARJ_SW environment
- variable. ARJ_SW is checked first for switches.
-
- Increasing the size of the comment input buffer to 2048 bytes and
- 25 lines can cause problems with versions of ARJ earlier than
- 0.15a. Unpredictable results will result from using an earlier
- version of ARJ to process an ARJ archive with comments longer than
- 1024 bytes. All users should upgrade to 0.20 as soon as possible.
- Archives produced by all ARJ releases are fully compatible with
- ARJ 0.20. This comment size problem also affects the use of the
- AV.EXE program. Users of AV.EXE should upgrade to the 1.10
- version.
-
- ***********************************************************************
-
- Fixed the problem of an update to an archive including itself.
- This also fixed the problem of a move command sometimes deleting the
- archive itself.
- Fixed the problem with memory usage and the "-js" switch.
- Improved the Huffman encoding and decoding routines.
- Improved the wildcard mechanism.
- Improved the recursion mechanism to work with non-wildnames.
- Improved "-s" to work with non-update commands.
- Improved volume sizing.
- Removed ".ARJ" suffix check for "-v" usage.
- Added "-vv" switch to beep terminal between volumes.
- Added support of both "/" and "-" as switch characters.
- Added "-jc" switch to check for RAW console mode.
- Added "-e1" switch to allow exclusion of the base directory name.
- Increased the speed of methods 3 and 4 to PKZIP like speed.
- Changed the create self-extractor switch to "-je".
- Changed "-d" switch to prompt for permission to delete files.
- Removed pause from "l" and "v" commands.
- Made the add, extract, test displays less verbose.
- Split help function into brief help and detailed help.
- Added system command option to "-v" switch to allow formatting,
- deleting, etc on target diskettes.
- Added "-jt" switch which causes ARJ to test the new temporary archive
- before it overwrites the original archive. When using a working
- directory, ARJ will test the copy operation. In the "m" command,
- ARJ does these test(s) before deleting any files.
- Added "-jr" recover switch to help recover data from damaged archives.
- Added "-jf" full path switch to allow drive and root to be stored.
- Added "-jp" pause switch to pause "l" and "v" commands.
- Added "-x" exclude switch to exclude filenames from processing.
- Added "-jv" verbose switch to display more information during "e", "t",
- "a", "f", "u", and "x" commands.
- Added "-jk" switch to keep the temporary archive after an abort. On a
- disk full error, the partial temporary archive will usually be usable.
- Increased archive comment size to 2048 bytes and 25 lines.
-
-
- ARJ 0.15a
-
- Fixed problem with getting a disk space error when extracting from a
- floppy disk using the -v option.
- Fixed the erase comment sequence to completely erase comment.
- Slightly (10%) speeded up extraction of files.
-
-
- ARJ 0.15
-
- ***IMPORTANT CHANGES***************************************************
-
- A bug in the -g option with certain stored files requires the ARJ
- 0.15 -jg option to extract.
-
- Method 4 compression has been improved, but it is NOT compatible
- with earlier versions of method 4. However, ARJ 0.15 will still
- test and extract old method 4 files correctly, but future versions
- of ARJ may not have that capability. ARJ never by default chooses
- method 4 to compress.
-
- ***KNOWN ISSUES********************************************************
-
- When updating an existing archive, ARJ does not eliminate the
- archive from wildcard inclusion. For example, ARJ u archive *.*
- will add archive.arj to itself if archive.arj already exists.
-
- ***********************************************************************

- Changed -h option to -ja.
