-
- V1.22 : Apr 2 1992
-
- - Fixed compression bug. Introduced in V1.20. Quite rare. (Mats Nyman)
-
- - Changed `-y' option behaviour. Now no longer appends `.lha' or `.lzh'
- suffix if archive name already contains one (Thanks to Mats Nyman).
-
- - Fixed problem where LhA would not restore file attributes with level 0
- headers even if you specified `-a' on extraction. (Thanks to Ken Krebs)
-
- V1.20 : Mar 26 1992
-
- - LhA now supports multivolume archives. On the evaluation version, only
- extracting and listing of multivolume archives is allowed. Currently
- the maximum number of volumes is 100 - if you go above this limit LhA
- won't complain but the behaviour is undefined (a crash is very likely
- to occur).
-
- - LhA now appends a lower-case `.lzh' or `.lha' instead of the upper-case
- suffixes in earlier versions. (Purely cosmetic)
-
- - Added support for OS2.0 local variables. Local variables override the
- global ENV:LHAOPTS if present.
-
- - Added `S' response to queries. Pressing `s' will cause LhA to assume
- negative response to all following queries of the same class. (i.e.
- generally skipping all following files).
-
- - Fixed bug in console font size detection on public screens other than
- the WB.
-
- - Fixed problem with updating/deleting files in/from archives on another
- device than the one the working directory is on.
-
- - LhA now reads default options from the environment variable LHAOPTS
- unless the `-I' switch is specified before the archive name. Note that
- the `-I' switch is special because it HAS to be specified directly
- after a dash (`-') like in "LhA -I a ram:test *.h", and not like this:
- "LhA -nI a ram:test *.h". You will get a warning message if LhA detects
- this. Specifying the `-I' option within LHAOPTS is not a good idea..
-
- - Implemented `-H' switch. LhA can now write level 1 and level 2 headers.
-
- - Fixed disk full detection problem when extracting stored files. (Juha
- Luoma).
-
- - LhA now emits no ANSI sequences at all when listing archives.
- (A.J.Brouwer).
-
- - Added `q' modifier to `l' and `v' commands to allow for creation of
- name-only archive listings. (Use `-N' option to suppress copyright
- msg). (Niklas Sjöberg)
-
- - Added `-Qd' option to make LhA ignore the delete protection file when
- moving files. (Will delete the file regardless of the delete protection
- flag state).
-
- - Added `-Qw' option to cause LhA to ignore wildcards. Useful when
- processing files containing wildcard characters (`~[]()*#?%). (Paul van
- der Heu).
-
- - LhA now can process SFX archives created with LhASFX. This means you can
- use LhA to test uploaded SFX archives on a BBS without taking the risk
- of running the `.RUN' file (which is dangerous since there's no way of
- knowing if it actually is a SFX archive or some type of `bomb').
-
- - Changed command line parsing to enable user to archive entire volumes
- or directories simply by specifying `df0:' and `dir/' as action file
- specs if they are followed by another directory name or are last on the
- command line. Idea from Pavel Vàña. See manual for more detailed
- explanation.
-
- - Added '-e' option to archive empty subdirectories (only valid when used
- together with '-r' option).
-
- - Added '-d' option to set archive file date to that of the newest file in
- the archive.
-
- - Added '-K' option to remove empty directories when moving files with the
- `m' command.
-
- - Changed console reset sequence once more to please some console
- emulators.
-
- - Added `-y' option to force suffix append.
-
- - Added -lh4- compression switch (`-1') serves no real purpose but I added
- it for the sake of completeness.
-
- - Fixed handling of level 2 headers. Would crash hard in earlier versions.
-
- - LhA now supports all extended header types.
-
- - All ARP dependencies removed. ARP is never used under KS2.x, but under
- 1.x ARP will be used if pattern.library does not exist. If neither ARP
- nor pattern.library exists when running under KS1.x, LhA uses its
- internal (inferior) pattern matching routines handling `?' and `*'
- only.
-
- - Added replace (`r') command. Works like update command but replaces
- files in archive regardless of datestamps. (Same effect as `u' command
- with option `-Qr').
-
- - Added `-Qr' option. This option disables the datestamp comparison for
- the `f' and `u' commands, so all files that exists in the archive will
- be replaced regardless of file modification dates.
-
- - Fixed cosmetic problem when using the `-n' option with the add/update
- commands. Would emit one linefeed for every present file in the
- archive.
-
- - Added `-Qd' option to delete autoshow files after showing/extracting.
-
- - Rewrote the -lh1- encoding routines in assembler, now -lh1- compression
- is about 1.6 times faster than before. (REGISTERED version only)
-
- - LhA now recognizes `.ZOM' files as being compressed and will not attempt
- further compression. (Olaf Barthel)
-
- - Implemented `-h' option to disable the homedir facility. Useful when
- running ToolManager, which passes directories as `dirname/'. (Oliver
- Knorr).
-
- - Implemented `-Qo' option to disable options after the command. Useful
- when running automated BBS file testing. (Suggested by Frederick Page)
- When this option is enabled all options must be specified before the
- command, like in LZ and LHArc.
-
- - Fixed bug in the automatic stack allocation code, which would cause LhA
- to crash when run together with MungWall with a CLI stack size of less
- than 6000 bytes. (Chris Green at CBM). The minimum stack size has also
- been reduced to 4000 bytes.
-
- - Some central list handling routines rewritten in assembler to reduce
- size.
-
- - When listing archives, LhA now prints years after 2000 in only two
- digits (before it was displayed as 100 etc. ). Normally, files with
- these dates have invalid datestamps.
-
- - The `p' command now no longer emit the in-between-file message or the
- console reset sequence when the `-q' option is used. `-n' can be used
- to suppress the in-between-file message alone. (Loren J. Rittle)
-
- - Fixed cosmetic `bug' caused by bug in KS1.3 console device. (Michael
- Beer).
-
- - Fixed progress indicator type 2 & 3 bug. Earlier versions would die
- when extracting zero-length files or empty directories with the `-D2'
- or `-D3' options. Thanks to Camillo Särs for reporting.
-
- V1.11 : Jan 19 1992
-
- - Fixed packing progress indicator type 3 (-D3) glitch.
-
- - Fixed the last bug in compression. The compression ratio has also been
- improved slightly over V1.10 (Thanks to Stefan Becker for reporting).
-
- - Fixed a few `bugs' in the manual.
-
- - Add operations now respect the -N option setting.
-
- - Add operations now respect the -F option setting.
-
- V1.10 : Jan 13 1992
-
- Major update; [all in a weeks work]
-
- - Bug in compression fixed, would show up mostly on large files, but had
- nothing to do with the size of the file really. This bug only affected
- LHA (-lh5-) compression. Because of the nature of this bugfix, the LHA
- compression is now better than before - but the difference is very
- slight.
-
- - Fixed rare bug in decompression code (several persons reported this and
- the offending file had been hatched via ADS). Handling of corrupted
- archives improved as well - V1.00 would crash on some bad data. This
- release will never do so.
-
- - Bug fixed where LhA would report an error and leave the temporary
- archive in the working directory. This happened when updating or
- deleting files in an archive on the same device as the work directory.
- Cause: DeleteFile in dos.library returns TRUE if delete was OK, and
- FALSE otherwise, I thought it was the other way around. (That's what
- you get for not reading the docs carefully enough).
-
- - Fixed stupid bug where LhA would refuse to do anything to delete-
- protected files, even if you didn't want to write to the file.
-
- - Fixed minor problem where LhA poked outside allocated memory (allocated
- 2 bytes too little for two buffers), this had no real effect however as
- the memory being stepped on never could get used by any other task
- anyway. (thanks to Peer Hasselmeyer for discovering this bug with
- MungWall).
-
- - Progress indicator update rate is now 4096 bytes in compression. Still
- hardcoded however.
-
- - Fixed problem where some corrupted archives or too long level 2 headers
- would cause LhA to crash. (Thanks to Jerry Sandstedt for reporting and
- supplying an offending archive).
-
- - Fixed problem when arp.library could not be opened. Now exits cleanly
- with a message and error return code.
-
- - LhA now reports already existing files (a and m commands) differently.
- In previous versions the source file with the whole path was printed,
- now LhA lists the name of the file as stored in the archive.
-
- - Recursive file collection changed somewhat, any explicit filespec will
- now be looked for only in the current home directory, and not in all
- scanned directories as before. If you want the old behaviour enclose the
- name in parantheses. By explicit filespec I mean a filespec without any
- wildcard characters.
-
- - If a directory name (without trailing `/' or `:') is specified as an
- action file with (a,f,u,m) commands, it is translated to `dir/*'. i.e.
- LhA will archive all files in that directory; if the `-r' option is
- enabled (recursive file collection) all files in the directory and it's
- subdirectories will be archived. Useful when using together with disk
- utilities such as Browser, DirOpus etc. Note that you cannot use this
- technique to archive an entire device/assigned directory, since LhA will
- treat this as a home directory specification. In this case, 'device:*'
- or `device:#?' must be used.
-
- - Archive attributes are no longer set to ----rw-d by default, on request
- from WB users. It can still be switched on with the -A switch however.
-
- - When attribute preservation is off, LhA now sets the attribute field on
- added files to --p-rwed (0x20) for MS-DOS compatibility.
-
- - Attributes are no longer preserved by default on extract commands. The
- archive update commands (a,f,u,m) still preserve attributes by default
- however.
-
- - Changed `vv' command, now all fields are OK.
-
- - LhA now emits a warning if the first action file specification is an
- explicit (no wildcards) name and the file does not exist. No error code
- is returned to the shell.
-
- - LhA now returns an error code when no archive matches the archive spec.
-
- - Fixed bug where LhA would print the wrong byte count for certain failed
- memory allocations. Purely cosmetic.
-
- - Worked around problem (bug?) in arp.library pattern matching routines.
- A pattern such as #> would cause memory corruption in prior versions of
- LhA. Although the arp documentation states that PreParse() will never
- produce parsed strings longer than the original, it sometimes does.
- (Thanks to Gary Chapman for reporting this problem)
-
- - Printout fixed for extraction with `-t' and `-T' options, now only
- prints the names of the files that were actually extracted.
-
- - Re-enabling of cursor changed to make certain console emulators happy.
- (Thanks to A.J.Brouwer)
-
- - Recursive file collection fixed. No longer scans unnecessary directories
- when explicit filespecs are given.
-
- - Files with names beginning with a dash (`-') can now be specified on
- the command line by using double-dashes (`--') as stated in the
- manual.
-
- - Files beginning with an at-sign (`@') can now be specified by using
- double at-signs.
-
- - Manual tidied up and corrected to treat the evaluation version only. No
- more references to registered-user-only options, commands or programs.
-
- - LhA now supports LhArc-style autoshow files. Autoshow files are files
- with names ending in `.displayme' (case insignificant).
-
- - Option (`-M') added for disabling of autoshow files. Autoshow files are
- disabled by default when the `-m' option is used.
-
- - LhA now promptly aborts with an error condition if a file cannot be
- opened for archiving. (Thanks to Magnus Holmgren for reporting this
- problem).
-
- - `Warning: premature end of file, no archive terminator seen' message
- removed, since many people thought this was a bug with LhA. Served no
- real purpose anyway.
-
- - Freshen command implemented.
-
- - LhA now restores empty subdirectories as created by AmigaDOS LhArc 1.30
- (with `-re' option) does not yet archive them however.
-
- - LhA extract commands now accept a destination-directory specification
- anywhere on the command line.
-
- - LhA now deletes temporary archives from the working directory when an
- update or freshen operation is interrupted.
