This file describes changes in the IO package.
4.8.0 (2022-10-18)
- Change minimal required GAP version to 4.11
- Add IO_getenv, IO_setenv, IO_unsetenv
4.7.3 (2022-09-25)
- Fix a build issue where running `make clean` would break the build
system (and hence building this package via GAP's BuildPackages.sh
script was broken, as that always runs `make clean` first)
- Various janitorial changes
4.7.2 (2021-10-21)
- Change `Random( RandomSource( IsRealRandomSource, "random" ), 1, 1 )` from `fail` to `1`.
- Improve `IO_CallWithTimeout` documentation
4.7.1 (2021-04-11)
- Add IO_realpath
- Handle crashing GAP in IO_CallWithTimeout
- Fix unpickling of permutation groups with no generators
- Switch to a new build system
- Various janitorial changes
4.7.0 (2019-07-17)
- Add IO_CallWithTimeout
- Remove CheckForUpdates, it was hopelessly broken
- Make IO_stat/IO_lstat/IO_fstat compatible with large files
- Various janitorial changes
4.6.0 (2019-03-15)
- Change minimal required GAP version to 4.10
- Fix for profiling when IO_fork is called
- Add License field to PackageInfo.g
- Fix various (harmless) compiler warnings
- Various internal changes to better work with newer (and future) GAP versions
(avoid including src/iostream.h, avoid C_NEW_STRING, modernize build system)
4.5.4 (2018-09-19)
- Add IO_getcwd to query the current working directory
- Fix ChangeDirectoryCurrent when used with relative paths
(it used to set GAPInfo.DirectoryCurrent to an invalid value)
4.5.3 (2018-09-18)
- Minimal GAP version is 4.9 (it already effectively was in 4.5.2, but PackageInfo.g
had not been updated)
4.5.2 (2018-08-21)
- Add exit status to IO_WaitPid (contributed by Chris Jefferson, PR #64)
- Make IO usable in the HPC-GAP threads (contributed by Mohamed Barakat, PR #65)
- Fix a failure in the HTTP part of the test suite
- Replace the deprecated `Elements` in examples by `AsSet`
- Clarify IO_WaitPid documentation
- Various minor changes to the build system and test suite
4.5.1 (2018-01-10)

- Compatible with GAP 4.9
- Add support for (un)pickling ranges and character tables
(contributed by Thomas Breuer)
- Add automatic call to InstallSIGCHLDHandler() when IO_Fork is used
directly or indirectly. As a consequence, code directly calling
IO_fork must now always call IO_WaitPid or the new IO_IgnorePid

- Move website to https://gap-packages.github.io/io/
- Change IO_PipeThroughWithError to also return the exit status of
the child process
- Improve test suite a little bit
- GAP 4.8 also provides ChangeDirectoryCurrent, so we only
define it if it does not already exist
- Don't wait for child processes to exit on GAP exit
4.4.4 (2014-11-19)
- Fix a bug in the IO_Write code, which for example could cause
IO_WriteLine to fail for certain long string
4.4.3 (2014-11-08)

- Recompress tst/test.txt with 'gzip --no-name'
- Fix package name in manual title ("io" -> "IO")

avoid data loss when files are not closed before exiting.

- Use AutoDoc to generate title page of the manual from PackageInfo.g
- Add Max Horn as a maintainer
