Message-ID: <20240201122118.380093-1-corinna-cygwin@cygwin.com> (raw)
I'm happy to announce update of the first Cygwin 3.5 release
==========================================================================
IMPORTANT DEPRECATION NOTES
==========================================================================
- Cygwin 3.4.10 was the LAST major version supporting
- Windows 7 / 8
- Windows Server 2008 R2 / 2012
- Cygwin 3.5.0 runs on
- Windows 8.1 / 10 / 11
- Windows Server 2012 R2 / 2016 / 2019 / 2022
- and (hopefully) all upcoming releases of Windows.
==========================================================================
Here's what's new and changed compared to Cygwin 3.4.10:
What's new:
-----------
- Drop support for Windows 7, Windows 8, Server 2008 R2 and Server 2012.
- Console devices (/dev/consN) are now accessible by processes attached
to other consoles or ptys. Thanks to this new feature, GNU screen and
tmux now work in the console.
- newgrp(1) tool.
- cygcheck has new options searching for available packages in the
cygwin distro, as well as getting extended info on available and
installed packages.
- fnmatch(3) and glob(3) now support named character classes, equivalence
class expressions, and collating symbols in the search pattern, i.e.,
[:alnum:], [=a=], [.aa.].
- Introduce /dev/disk directory with various by-* subdirectories which
provide symlinks to disk and partition raw devices:
by-drive/DRIVE_LETTER -> ../../sdXN
by-label/VOLUME_LABEL -> ../../sdXN
by-id/BUSTYPE-[VENDOR_]PRODUCT_[SERIAL|0xHASH][-partN] -> ../../sdX[N]
by-partuuid/MBR_SERIAL-OFFSET -> ../../sdXN
by-partuuid/GPT_GUID -> ../../sdXN
by-uuid/VOLUME_SERIAL -> ../../sdXN
by-voluuid/MBR_SERIAL-OFFSET -> ../../sdXN
by-voluuid/VOLUME_GUID -> ../../sdXN
The subdirectories by-drive and by-voluuid are Cygwin specific.
- Introduce /proc/codesets and /proc/locales with information on
supported codesets and locales for all interested parties. Locale(1)
opens these files and uses the info for printing locale info like any
other process could do.
- Add support for GB18030 codeset.
- Add support for lseek flags SEEK_DATA and SEEK_HOLE, a GNU extension.
- New API calls: posix_spawn_file_actions_addchdir_np,
posix_spawn_file_actions_addfchdir_np.
- New API calls: c8rtomb, c16rtomb, c32rtomb, mbrtoc8, mbrtoc16, mbrtoc32.
- New API call: close_range (available on FreeBSD and Linux).
- New API call: fallocate (Linux-specific).
- Implement OSS-based sound mixer device (/dev/mixer).
What changed:
-------------
- posix_spawnp no longer falls back to starting the shell for unrecognized
files as execvp. For the reasoning, see
https://www.austingroupbugs.net/view.php?id=1674
- FIFOs now also work on NFS filesystems.
- Enable automatic sparsifying of files on SSDs, independent of the
"sparse" mount mode.
- When RLIMIT_CORE is more than 1MB, a core dump file which can be loaded by gdb
is now written on a fatal error. Otherwise, if it's greater than zero, a text
format .stackdump file is written, as previously.
- The default RLIMIT_CORE is now 0, disabling the generation of core dump or
stackdump files.
Fixes:
------
- Fix arc4random reseeding after fork(2).
