This makes - life more bearable when dealing with zip64. - - * Compress::Zlib.pm - - documented that memGunzip cannot cope with concatenated gzip data - streams. - - * Changed test harness so that it can cope with PERL5OPT=-MCarp=verbose - [RT# 47225] - - * IO::Compress::Gzip::Constants.pm - - GZIP_FEXTRA_MAX_SIZE was set to 0xFF. Should be 0xFFFF. This - issue came up when attempting to unzip a file created by MS - Office 2007. - - 2.020 3 June 2009 - - * IO::Uncompress::Base.pm - - Fixed problem with LimitOutput where a call to uncompress - created more uncompressed output, but didn't consume any of - the input buffer. The symptom is the underlying compression - library (zlib or bzip2) thinks the input stream is corrupt. - [RT #46582] - - 2.019 4 May 2009 - - * IO::Uncompress::Adapter::Bunzip2 - - Fixed problem with EOF check. - - 2.018 3 May 2009 - - * IO::Unompress::Bunzip2 - - The interface to Compress-Raw-Bzip2 now uses the new LimitOutput - feature. This will make all of the bzip2-related IO-Compress modules - less greedy in their memory consumption. - - * IO::Compress::Zip - - Fixed exTime & exUnix2 - - - Fixed 'Use of uninitialized value in pack' warning when using - ZIP_CM_STORE. - - 2.017 30 March 2009 - - * Merged IO-Compress-Base, IO-Compress-Bzip2, IO-Compress-Zlib & - Compress-Zlib into IO-Compress. - - * The interface to Compress-Raw-Zlib now uses the new LimitOutput - feature. This will make all of the zlib-related IO-Compress modules - less greedy in their memory consumption. - - * Removed MAN3PODS from Makefile.PL - - * A few changes to get the test harness to work on VMS courtesy of - Craig. A. Berry. - - * IO::Compress::Base & IO::Uncompress::Base - Downgraded some croaks in the constructors to just set $! (by letting - the code attempt to open a file and fail). - This makes the behavior more consistent to a standard open. - [RT #42657] - - * IO::Uncompress::Base - Doing a seek with MultiStream could drop some of the uncompressed - data. Fixed. - - * IO::Compress::Zip - - Fixed problem with the uncompressed & uncompressed fields when - zip64 is enabled. They were set to 0x0000FFFF instead of - 0xFFFFFFFF. Also the ZIP64 extra field was 4 bytes short. - Problem spotted by Dino Chiesa. - - * IO::Uncompress::Unzip - - use POSIX::mktime instead of Time::Local::timelocal to convert - the zip DOS time field into Unix time. - - * Compress::Zlib - - Documented Compress::Zlib::zlib_version() - - - 2.015 3 September 2008 - - * Makefile.PL - Backout changes made in 2.014 - - 2.014 2 September 2008 - - * Makefile.PL - Updated to check for indirect dependencies. - - 2.013 18 July 2008 - - * IO::Compress::Base - - Allow IO::Compress::Base::Parameters::parse to accept an - IO::Compress::Base::Parameters object. - - 2.012 15 July 2008 - - * IO::Compress::Base - - Silenced an uninitialised value warning when reading a line - at a time from a zip file where the content uses ZIP_CM_STORE. - [Problem spotted & fixed by Jeff Holt] - - * IO::Compress::Base & IO::Uncompress::Base - - local-ise $!, $? et al in the DESTROY methods. - - 2.011 17 May 2008 - - * IO::Compress::Base - - Fixed problem that prevented the creation of a zip file that - contained more than one compression method. - - * IO::Compress::Base::Common - - The private Validator class in this module clashes with another - CPAN module. Moved Validator into the IO::Compress::Base::Common - namespace. - [RT #35954] - - * IO::Uncompress::Unzip - - Print an error message if the zip file contains a - member compressed with bzip2 and IO::Uncompress::Bunzip2 is - not available. - - Could not cope with mixed compression zip files. For example a - zip file that contains both STORED and DEFLATED content. - [RT #35573] - - 2.010 5 May 2008 - - * Fixed problem that meant Perl 5.10 could not upgrade this module. - [RT #35342 & 35341] - - 2.009 20 April 2008 - - * Removed the alpha status from File::GlobMapper - - * IO::Compress::Base - When writing output never output a zero length buffer. - Done to improve interoperability with other tied filenandle - modules. - - * Changed IO::Uncompress::Base to not use the offset parameter of - the read method when reading from a filehandle. - - The object returned from Net::FTP::retr implements a non-standard - read method. The third parameter is used for a timeout value - rather than an offset. - [rt.cpan#33231] - - * Changed IO::Uncompress::Base to not use the eof method when - reading from a filehandle. - - The object returned from Net::FTP::retr implements both the read - method and the eof method. Unfortunately the implementation of - the read method uses non-buffered IO (by using sysread) while - the eof method uses buffered IO. Mixing buffered and non-buffered - IO results in data corruption. - - * IO::Compress::Zip - - - Added exUnix2 option to allow storing of UID & GID. - - When running on a Unix derivative the ExtAttr option now defaults - to the equivalent of 0666. For all other systems the default - remains 0. - - * Compress::Zlib - - Minor documentation issue with flush. - [rt.cpan.org #31446] - - - 2.008 2 November 2007 - - * Minor documentation changes in README - - * t/compress/truncate.pl - EBCDIC Cleanup. - - * IO::Compress::Gzip::Constants.pm - Tidied up the character classes used to defined invalid - FNAME & FCOMMENT fields for EBCDIC. - - * Compress::Zlib - lib/Compress/Zlib.pm -- 1.x Backward Compatability issues - gzclose - documented return value was wrong, should be 0 for ok. - gzflush - return value didn't match 1.x, should return 0 if ok. - [rt.cpan.org #29215] and Debian bug #440943 http://bugs.debian.org/440943 - - 2.006 1 September 20007 - - * Makefile.PL - Added INSTALLDIRS directive to install as a core module when built - on a perl >= 5.9. - - * IO::Uncompress::RawDeflate - - - Fixed export problem - "$RawDeflateError" and "rawdeflate" were - not being exported with ":all". - - * Compress::Zlib - - t/03zlib-v1.t - Fixed crc32 and adler32 tests in to remove ascii assumption. - - - lib/Compress/Zlib.pm - Make gzreadline not support $/, just like in Compress::Zlib 1.x - Folk who want $/ with readline support can get it in - IO::Uncompress::Gunzip. [rt.cpan.org #28663] and - Debian bug #435656 http://bugs.debian.org/435656 - - - 2.005 18 June 2007 - - * Stephen Turner reported a problem when using IO::Uncompress::Gunzip - with XML::Parser. Turns out there were two issues. - - Firstly an IO::Uncompress object isn't an IO::Handle. It is now. - - Secondly the implementation of "read" wasn't honouring this - - SCALAR will be grown or shrunk to the length actually read. - - In particular it didn't do the right thing on EOF. - This has been fixed. - - * IO::Compress::Gzip & IO::Uncompress::Gunzip - - - RFC1952 says that the FNAME & FCOMMENT header fields must be ISO - 8859-1 (LATIN-1) characters. The code can optionally police this. - Added a fix for this logic when running on EBCDIC. - - * Compress::Zlib - Added info about removing Compress::Zlib version 1, before - installing version 2. - - 2.004 3 March 2007 - - * Made seek less wasteful of memory. - - * IO::Compress::Zip - - - Added Zip64 documentation. - - - Fixed extended timestamp. - Creation time isn't available in Unix so only store the - modification time and the last access time in the extended field. - - - Fixed file mode. - - - Added ExtAttr option to control the value of the "external file - attributes" field in the central directory. - - - Added Unix2 extended attribute ("Ux"). - This stores the UID & GID. - - * IO::Compress::Gzip - - - Fixed 050interop-gzip.t for Windows - - * IO::Compress::Bzip2 - - - Fixed 050interop-bzip2.t for Windows - - * Compress::Zlib - - - rewrote memGzip using IO::Compress::Gzip::gzip - - 2.003 2 January 2007 - - * Added explicit version checking - - 2.002 29 December 2006 - - * Documentation updates. - - * Added IO::Handle to the ISA test in isaFilehandle - - * Add an explicit use_ok test for Scalar::Util in the test harness. - The error message reported by 01misc implied the problem was - somewhere else. - Also explictly check that 'dualvar' is available. - - * Compress::Zlib - - Fix append mode with gzopen. - rt-cpan.org 24041 - - - Allow gzopen to read from and write to a scalar reference. - - 2.001 1 November 2006 - - * Remove beta status. - - 2.000_14 26 October 2006 - - * IO::Uncompress::Base - Added support for $/ in record mode - - * IO::Uncompress::Base - The readline interface was substantially slower than the 1.x - equivalent. This has now been sorted. - Thanks to Andreas J. Koenig for spotting the problem. - - * IO::Uncompress::AnyUncompress - Added IO::Uncompress::Lzf to the list of supported uncompresors. - - * IO::Uncompress::Base - Added TrailingData to one-shot interface. - - * IO::Uncompress::AnyUncompress - Remove raw-deflate (RFC1951) from the default list of compressors - to check. - It can still be included if the new RawInflate parameter is - supplied. - This change was made because the only way to tell if content is - raw-deflate is to attempt to uncompress it - a few false positives - have popped up recently, which suggests that auto-detecting raw - deflate is far from perfect. - The equivalent change has been made to IO::Uncompress::AnyInflate. - [Core patch #28445] - - * Don't check that filehandles are writable. It would seem that - "-w *STDOUT" on windows returns false. - [Core Patch #28415] - - * IO::Uncompress::Deflate - Beefed up the magic signature check. Means less false positives - when auto-detecting the compression type. - - * IO::Uncompress::UnZip - Tighten up the zip64 extra field processing to cope with the case - wheere only some of the local header fields are superceeded. - - * IO::Uncompress::AnyInflate - Remove raw-deflate (RFC 1951) from the default list of compressors - to check. - It can still be included if the new RawInflate parameter is - supplied. - This change was made because the only way to tell if content is - raw-deflate is to attempt to uncompress it - a few false positives - have popped up recently, which suggests that auto-detecting raw - deflate is far from perfect. - The equivalent change has been made to IO::Uncompress::AnyUncompress. - [Core patch #28445] - - 2.000_13 20 June 2006 - - * Store compress & uncompressed sizes as 64-bit. - - * For one-shot uncompression, like this - - unzip "some.zip" => \@a, MultiStream => 1; - - Push each uncompressed stream from "some.zip" onto @a. - - * Added IO::Compress::Base::FilterEnvelope - - * Added IO::Uncompress::Base::nextStream - - * The '-' filehandle now maps to either *STDIN or *STDOUT. - This keeps mod_perl happier. Was using these before - - new IO::File("<-") - new IO::File(">-") - - * Preliminary support for reading zip files with zip64 members. - - 2.000_12 3 May 2006 - - * Moved the code for creating and parsing the gzip extra field into - IO::Compress::Zlib::Extra.pm so that IO::Compress::Zip & - IO::Uncompress::Unzip can use it as well. - - * Added ExtraFieldLocal & ExtraFieldCentral options to IO::Compress::Zip. - These allow the creation of user-defined extra fields in the local - and central headers, just like the ExtraField option in - IO::Compress::Gzip. - - * Moved the zip constants into IO::Compress::Zip::Constants - - * Added exTime option to IO::Compress::Zip. - This allows creation of the extended timestamp extra field. - - * Added Minimal option to IO::Compress::Zip. - This disables the creation of all extended fields. - - * Added TextFlag option to IO::Compress::Zip. - - * Documented Comment and ZipComment options in IO::Compress::Zip. - - * Compress::Zlib - Fixed gzread to zap the output buffer to an empty string when zero - bytes are requested. This matches the behaviour of C::Z 1.x - - 2.000_11 10 April 2006 - - * Transparent + InputLength made more robust where input data is not - compressed. - - * Updated Documentation for zip modules. - - * Changed IO::Compress::Zip 'Store' option to 'Method' and added - symbolic constants ZIP_CM_STORE, ZIP_CM_DEFLATE and ZIP_CM_BZIP2 to - allow the compression method to be picked by the user. - - * Added support to allow bzip2 compressed data to be written/read - with IO::Compress::Zip and IO::Uncompress::Unzip. - - * Beefed up 050interop-gzip.t to check that the external gzip command - works as expected before starting the tests. This means that - this test harness will just be skipped on problematic systems. - - * Merged core patch 27565 from Steve Peters. This works around a - problem with gzip on OpenBSD where it doesn't seem to like - compressing files < 10 bytes long. - - * Beefed up 050interop-bzip2.t to check that the external bzip2 command - works as expected before starting the tests. This means that - this test harness will just be skipped on problematic systems. - - 2.000_10 13 March 2006 - - * AnyUncompress doesn't assume that IO-Compress-Zlib is installed any - more. - - * Documentation updates. - - * Compress::Zlib - Changed gzread so that its behaviour matches C::Z::gzread 1.x if it - is called after eof. In this case it will write an empty string - into the output parameter. This change is solely for backward - compatability reasons. - - 2.000_09 3 March 2006 - - * Released to CPAN. - - 2.000_08 2 March 2006 - - * Split IO::Compress::Base into its own distribution. - - * Split IO::Compress::Bzip2 into its own distribution. - - * Added opened, autoflush and input_line_number. - - * Beefed up support for $. - - * Split IO::Compress::Zlib into its own distribution. - - * Beefed up support for zip/unzip - - * Breakout zlib specific code into separate modules. - - * Limited support for reading/writing zip files - - 2.000_06 5 October 2005 - - * Added eof parameter to Compress::Zlib::inflate method. - - * Fixed issue with 64-bit - - 2.000_05 4 October 2005 - - * Renamed IO::* to IO::Compress::* & IO::Uncompress::* - - 2.000_04 23 September 2005 - - * Fixed some more non-portable test that were failing on VMS. - - * fixed problem where error messages in the oneshot interface were - getting lost. - - 2.000_03 12 September 2005 - - * Fixed some non-portable test that were failing on VMS. - - * Fixed export of zlib constants from the IO::* classes - - 2.000_02 6 September 2005 - - * Split Append mode into Append and Merge - - * Fixed typos in the documentation. - - * Added pod/FAQ.pod - - * Added libscan to Makefile.PL - - * Added InputLength for IO::Gunzip et al - - 2.000_01 22 August 2005 - - * Fixed VERSION in Compress::Gzip::Constants - - * Removed Compress::Gzip::Info from the distribution. - - 2.000_00 21 August 2005 - - * First Beta relase of Compress::zlib rewrite. - -Compress-Zlib version 1 Changes - - 1.38 - 6 September 2005 - - * Integrate core change 25304 -- Symbian Update - - * Added libscan to Makefile.PL - - 1.37 - 12 August 2005 - - * Change to t/03examples.t for VMS from Abe Timmerman - - 1.36 - 3 August 2005 - - * Renamed zlib-src-1.2.3 to zlib-src to help VMS - - * Fixed Makefile.PL for VMS - - * Fixed t/03examples.t for VMS - - * Added a couple of notes about incompatibility with Unix compress. - - 1.35 - 16 July 2005 - - * Updated zlib source to 1.2.3 - - * Fixed problem with where two calls to gzclose would hang the debugger. - See https://rt.cpan.org/Ticket/Display.html?id=13789 - - * Added code from Alexey Tourbin to use XSLoader when available, - and DynaLoader otherwise. - - * Documented that the compress & uncompress functions were not - the same as the Unix utilities of the same name. - - * Fixed 05gzsetp -- it left a temp file hanging around. - - * Integrate core change 24787 - SvUPGRADE returns void in blead - - * Integrate core change 24788 - Makefile.PL adjustments for the core - - - 1.34 - 30 January 2005 - - * Fixed typo in the README - - * Fixed examples.t on Win32 where paths have embedded whitespace. - - * Fix for Cygwin and core integration from Jos I. Boumans - - * Upgrade zlib source to 1.2.2 - - 1.33 - 14 January 2004 - - * Reworked Makefile.PL to avoid creating a private copy of zlib. - This both simplifies the build, plus it makes life easier for VMS. - - * Patches for Makefile.PL to get it to work on VMS supplied by - Craig A. Berry. - - * memGunzip has very slow on FreeBSD. Turns out to be down to - the way realloc works on FreeBSD. Changed both inflate & deflate - to use exponentially increasing buffer sizes when they need to - realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD - memory allocation. - - 1.32 - 26 November 2003 - - * Steve Hay reported a problem on rt.cpan.org with Windows and - MSCV++ 6.0 where the source from the zlib directory was getting - installed with the rest of the module. - https://rt.cpan.org/Ticket/Display.html?id=1741 - - This has been fixed by renaming the "zlib" directory to "zlib-src" - thus avoiding a conflict with the name of this Perl module. - - * Fixed a bug in the inflate method where the input buffer is an - lvalue (via substr). Problem & solution reported by Salvador Fandiqo. - - * Tightened up the logic in Makefile.PL when BUILD_ZLIB is - True. Issue spotted by Ralf S. Engelschall. - - 1.31 - 29 October 2003 - - * Reinstated the creation of .bak files - $^I seems to need a - backup file on Windows. For OpenVMS, the extenstion _bak is used. - - 1.30 - 28 October 2003 - - * Bundled a sub-set of the zlib source with the module and changed - the default make behaviour to build with the included zlib source. - The previous behaviour of using a pre-built zlib library is - still available for those that want it. - - * Added prototypes to the subs in Zlib.pm that didn't already have - them. Patch from Ed Avis. - - * No .bak files are created by Makefile.PL any more - this keep - distclean much happier. Patch suggested by Ed Avis. - This also fixes a similar problem reported by Dr. Martin Zinser - on OpenVMS. - - * Documentation for some of the gz functions updated. - - * Format strings modified in DispStream to keep OpenVMS happy. - Problem reported by Dr. Martin Zinser. - - - 1.22 - 17 June 2003 - - * Makefile.PL now displays a warning about not installing - Compress::Zlib via the CPAN shell. - - * Fix to allow intermingling of gzread & gzreadline - patch - supplied by Doug Perham. - - * memGunzip will silently now work if the gzip trailer is - missing. Some HTTP Origin Servers seem to leave it out. - - 1.21 - 28 April 2003 - - * Tests 148 & 150 from t/02zlib.t were failing on redhat 9. - - * Added a few words about the problems with Mac OS X to the README file. - - 1.20 - 4 April 2003 - - * Fixed bug in gzopen where $gzerrno wasn't being set correctly. - The symptom was $gzerrno was set to Z_MEM_ERROR although the file - was opened ok. If gzopen failed, $gzerrno was being set correctly. - This problem wasn't spotted before because the typical test - to determine whether gzopen passed or failed was to check its - return value. - - 1.19 - 31 October 2002 - - * fixed a problem with t/02zlib.t that was failing with redhat 8. - - 1.18 - 24 October 2002 - - * fixed a Win32 problem in t/02zlib.t by changing sysread to read. - - * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new - variable to config.in to flag an old version of zlib. Split - out the tests for gzsetparams into t/05gzsetp.t - - 1.17 - 23 May 2002 - - * Moved the test to check the versions of libz & zlib.h into a separate - file and added troubleshooting notes to README. - - * In gzopen, only attempt to call "tell" for normal files. - - * Fixed to work in taint mode. - - * Broke changes out of README into Changes file. - - * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH. - zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */ - - 1.16 - 13 December 2001 - - * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..." - working. - - 1.15 - 4th December 2001 - - * Changes a few types to get the module to build on 64-bit Solaris - - * Changed the up/downgrade logic to default to the older constructs, and - to only call a downgrade if specifically requested. Some older versions - of Perl were having problems with the in-place edit. - - * added the new XS constant code. - - 1.14 - 27th August 2001 - - * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for - reporting the bug and to Anton Berezin for fixing it for me. - - 1.13 - 31st June 2001 - - * Make sure config.in is consistant when released. - - 1.12 - 28th April 2001 - - * Modified Makefile.PL to only enable the warnings pragma if - using perl 5.6.1 or better. - - 1.11 - 17th February 2001 - - * Added logic in Makefile.PL to toggle between using $^W and - the warnings pragma in the module. - - * The module, the examples & the test harness are now all strict - & warnings clean. - - 1.10 - 5th February 2001 - - * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR. - - 1.09 - 15th January 2001 - - * Silenced a few compiler warnings. - - * Updated zlib home site in README & Zlib.pm to www.info-zip.org - - * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR - -- spotted by Frank Martini. - - * Mention Archive::Zip - - * added memGunzip. This is largely based on code provided by Jim Leonard. - - * $deflate->flush can now take an optional parameter. Valid - values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH - and Z_FINISH. The default is Z_FINISH. - - 1.08 - 6 Jan 2000 - - * uncompress was clobbering its input parameter. Now it doesn't. - This bug was spotted by Deven T. Corzine. - - * If a variable that only ever contained a number was given - to compress or deflate, it would not be compressed properly. Now - it will be coerced to a string and then compressed. This bug - was spotted by Deven T. Corzine. - - 1.07 - 27 Nov 1999 - - * ANSI-ified the static functions in Zlib.xs - - * Added the ability to build zlib along with the module. - This feature is 90% based on a Makefile provided by Gurusamy - Sarathy. - - 1.06 - 20 Sep 1999 - - * Fixed a nasty problem where inflate could truncate the data - returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au> - for both spotting the problem and fixing the bug. - - * Added a note about the undocumented features in zlib that are - required when accessing zip files. - - * gzclose will now get called automatically when the gzip object is - destroyed. - - 1.05 - 3 June 1999 - - * Previous release used newSVpvn, which doesn't exist in 5.004_04 - or earlier. Changed to use newSVpv instead. - - * The module needs Perl 5.004 or better, so updated the version - checking in Zlib.pm and Makefile.PL - - 1.04 - 27 May 1999 - - * Bug 19990527.001: compress(undef) core dumps -- Fixed. - - 1.03 - 17 Mar 1999 - - * Updated to use the new PL_ symbols. - Means the module can be built with Perl 5.005_5* - - 1.02 - 31 Jan 1999 - - * The return codes for gzread, gzreadline and gzwrite were - documented incorrectly as returning a status code. - - * The test harness was missing a "gzclose". This caused problem - showed up on an amiga. Thanks to Erik van Roode for reporting - this one. - - * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch. - - 1.01 - 23 Nov 1997 - - * A number of fixes to the test suite and the example scripts to - allow them to work under win32. All courtesy of Gurusamy - Sarathy. - - 1.00 - 14 Nov 1997 - - * Fixed crc32 & adler32. They were very broken. - - * The following functions can now take a scalar reference in - place of a scalar for their buffer parameters: - - compress - uncompress - deflate - inflate - crc32 - adler32 - - This should mean applications that make use of the module don't - have to copy large buffers around. - - - * Normally the inflate method consumes I<all> of the input buffer - before returning. The exception to this is when inflate detects - the end of the stream (Z_STREAM_END). In this case the input - buffer need not be completely consumed. To allow processing of - file formats that embed a deflation stream (e.g. zip, gzip), - the inflate method now sets the buffer parameter to be what - remains after inflation. - - When the return status is Z_STREAM_END, it will be what remains - of the buffer (if any) after deflation. When the status is Z_OK - it will be an empty string. - - This change means that the buffer parameter must be a lvalue. - - * Fixed crc32 and adler32. They were both very broken. - - * Added the Compress::Zlib::memGzip function. - - 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4. - - The optional parameters for deflateInit and inflateInit can now - be specified as an associative array in addition to a reference - to an associative array. They can also accept the -Name - syntax. - - gzopen can now optionally take a reference to an open - filehandle in place of a filename. In this case it will call - gzdopen. - - Added gzstream example script. - - 0.4 - Upgrade to support zlib 0.99 - - Added dictionary interface. - - Fixed bug in gzreadline - previously it would keep returning - the same buffer. This bug was reported by Helmut Jarausch - - Removed dependency to zutil.h and so dropped support for - - DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead) - DEF_WBITS (use MAX_WBITS instead) - - 0.3 - Added prototype specification. - - 0.2 - Fixed a minor allocation problem in Zlib.xs - - 0.1 - first alpha release. 2nd October 1995 |
