2 1.2.4 7th Oct 92 1st public release.
4 1.2.5 9th Oct 92 Fixed bug in misc.c::riscos_path() that caused nspark
5 to core dump under SCO UNIX.
7 1.2.6 19th Oct 92 Added -x option as an alternative to -u. Changed
8 unix.c::filestamp() so that timelocal(3) is only used
9 for SunOS, and mktime(3) is used for all other
12 1.2.7 23rd Oct 92 Minor cosmetic changes... I should really leave this
15 1.2.8 6th Nov 92 Fixed function definition for unarc.c::prompt_user()
16 (was defined the ANSI C way).
18 Fixed io.c::read_header() so it doesn't read the
19 load/exec/attr fields if the archive isn't an
22 Corrected comments in compress.c about what crunch
23 and squash methods were.
25 Slight change to algorithm in crc.c::calccrc(), though
26 no functional changes made.
28 1.2.9 9th Nov 92 compress.c: Moved offset and size from getcode() into
29 global scope so that uncompress() can re-initialise
30 them each time it is called.
32 pack.c/pack.h: Added putc_init() to initialise the
33 static variables used by putc_ncr().
35 1.2.10 12th Nov 92 Fixed bug with realloc() size in misc.c: uplevel().
36 (reported by arb@comp.lancs.ac.uk).
38 1.2.11 7th Dec 92 Reformatted all source files using Emacs C-Mode (4-
39 space tabs etc.). Slight change to unarc.c::unarc()
40 logic when printing file details during unarchiving.
42 1.3Beta 8th Dec 92 Added -a option to allow filetypes to be appended
43 to filenames as they are unarchived. This is to allow
44 Acorn <-> UNIX NFS to work correctly.
45 (requested by dhmyrdal@pvv.unit.no)
47 1.3 9th Dec 92 Changed -a option to -T, made filetypes append in
48 lowercase hex rather than uppercase.
50 1.3.1 9th Dec 92 Changed ret from int in io.c::check_stream(). #ifdef'd
51 out write_halfword() and write_word() in io.c/io.h .
53 1.3.2 22nd Dec 92 misc.c: Changed #include <malloc.h> to
56 1.4 23rd Dec 92 unarc.c: added total-printing if in verbose mode.
58 NEW MAINTAINER: Andrew Brooks, arb@comp.lancs.ac.uk.
60 1.5 5th Mar 93 Added code to compile on RISC OS: mkfiles/acorn,
61 acorn.c, changes to io.c, unarc.c, main.c, io.h to
62 add prototypes needed.
64 1.6 20th Aug 93 main.c: Add -C option to convert filenames to lowercase
65 io.c: allow top-bit-set characters in RISCOS filenames.
66 compress.c, unarc.c: prevent output if in quiet mode.
68 1.7 20th Aug 93 Added code to read headers from ArcFS archives.
69 Changes to io.c, unarc.c, mkfiles. Added arcfs.[ch]
70 WARNING: Code is unfinished: only the list option (-l)
71 can be used (and timestamps will be incorrect). Trying
72 to test or extract from the archive will fail, and
73 probably dump core. Please add the necessary
74 code if you can, I don't have time at the moment.
76 1.7.1 4th Mar 94 Fixed many bugs in ArcFS code: changes to unarc.c,
77 compress.c also. Still no timestamps, and files
78 extracted are too long by a few null bytes for some
79 reason (complen is too large, but why?), so CRC fails.
81 1.7.2 26th Oct 94 Fixed date and time conversion for ArcFS archives.
82 Added manual pages supplied by Duncan (?)
83 (m91dps@ecs.oxford.ac.uk).
85 1.7.2a 9th Nov 94 Altered unix makefile to call ./mkendian not mkendian
86 as suggested by Tom Tromey (tromey@busco.lanl.gov).
87 Added rename scripts for RISC OS/UNIX.
89 1.7.3 12th Dec 94 Finally fix ArcFS archive extraction, fixes in
90 arcfs.c, unarc.c, io.c and crc.c. Modifications
91 to manual pages to correct errors and add new details.
93 1.7.4 6th Jan 95 Added Windows NT and Alpha support by Alun Jones
95 Restructured directories and added executables for
96 RISC OS, Sun OS 4.1.3 and Solaris 2.3.
97 Added executables for Linux, MIPS and Alpha supplied
99 Updated manual pages for new file formats.
100 Added text versions of manual pages for those without
103 1.7.5 25th Jan 95 Bug fixes in compress.c, thanks to all who reported
104 the problem. Included binaries that report version
105 1.7.4 should not be exhibit the bug as it was caused
106 by a last-minute source change (mae culpa!).
108 1.7.6 01th Aug 95 DOS port. (Beta by Bob Brand, bob@wop.wtb.tue.nl,
109 or B.A.Brand@wtb.tue.nl, addresses valid until
110 at least Oct 1st, 1996), fido: 2:2801/208.2.
111 Removed floating point operation in
112 arcfs.c::arcfs_read_header().
113 Made htab[] and codetab[] arrays in compress.c
114 dynamically allocated arrays (DOS version only!).
115 Made misc.c::basename() insensitive for null-
116 pointers. (IRIX's strlen() and a few other string-
117 functions coredump on null-pointers. Should not
118 happen under normal execution. But it can happen
119 in the DOS version running under DOS 2.x.)
120 Renamed io.h to sparkio.h (conflict with Borland
122 Removed `Does not support DOS' from BUGS file.
123 Added `Does not time/date stamp directories
124 under DOS or WINNT' to BUGS file.
125 Included executables for SGI IRIX 4.x and 5.x.
127 1.7.7 17th March 1999 -I option Mark Usher, marku@magnet.at
128 The -I option has been added to extract the individual
129 files with an extra .inf file that contains the
130 information relevant to that file. This should help
131 people who use BBC emulators to read the files into
133 The WinNT directory has been changed to Win32.
