-@section Release Beta 20.1 (Dec 4 1998)
-
-This is a bug fix update to the Beta 20 release.
-
-The main change is an improved version of the Cygwin library although
-there are also a couple of other minor changes to the tools.
-
-@subsection Changes in specific tools:
-
-The "-mno-cygwin" flag to gcc now include the correct headers. In 20.0,
-it included the Cygwin headers which was incorrect.
-
-The "-pipe" flag to gcc works correctly now.
-
-The cygcheck program now reassures users that not finding cpp is the
-correct behavior.
-
-The "-b" flag to md5sum can now be used to generate correct checksums
-of binary files.
-
-The libtermcap library has been added to the compiler tools sources.
-It is the new source of the termcap library and /etc/termcap file.
-
-The less pager (using libtermcap) has been added to the binary
-distribution.
-
-@subsection Changes in the Cygwin API (cygwin.dll):
-
-This version of Cygwin is backwards-compatible with the beta 20 and 19
-releases. The library is now much more stable under Windows 9x and the
-bugs affecting configures under 9x (and NT to a lesser extent) have
-also been fixed.
-
-The bug that made it necessary to start the value of the CYGWIN
-environment variable with two leading spaces has been fixed.
-
-The serial support in the select call has been fixed.
-
-Handling of DLLs loaded by non-cygwin apps has been improved. Bugs in
-dlopen have been fixed.
-
-Passing _SC_CHILD_MAX to the sysconf function now yields CHILD_MAX (63)
-instead of _POSIX_CHILD_MAX (3).
-
-Several minor path bugs have been fixed. Including the one that
-caused "mkdir a/" to fail.
-
-The include file sys/sysmacros.h has been added. Added missing protos
-for wcslen and wcscmp to wchar.h.
-
-__P is now defined in include/sys/cdefs.h. To support that last change,
-the top-level Makefile.in now sets CC_FOR_TARGET and CXX_FOR_TARGET
-differently.
-
-Cygwin now exports the following newlib bessel functions: j1, jn, y1,
-yn.
-
-Several tty ioctl options have been added: TCGETA, TCSETA, TCSETAW, and
-TCSETAF.
-
-Several functions cope with NULL pointer references more gracefully.
-
-Problems with execution of relative paths via #! should be fixed.
-
-@section Release Beta 20 (Oct 30 1998)
-
-This is a significant update to the Beta 19 release. In addition to an
-EGCS-based compiler and updated tools, this release includes a new
-version of the Cygwin library that contains many improvements and
-bugfixes over the last one.
-
-@subsection The project has a new name!
-
-Starting with this release, we are retiring the "GNU-Win32" name for the
-releases. We have also dropped the "32" from Cygwin32. This means that
-you should now refer to the tools as "the Cygwin toolset", the library
-as "the Cygwin library" or "the Cygwin DLL", and the library's interface
-as "the Cygwin API".
-
-Because of this name change, we have changed any aspects of the library
-that involved the name "Cygwin32". For example, the CYGWIN32
-environment variable is now the CYGWIN environment variable. API
-functions starting with cygwin32_ are still available under that form
-for backwards-compatibility as well as under the new cygwin_-prefixed
-names. The same goes for the change of preprocessor define from
-__CYGWIN32__ to __CYGWIN__. We will remove the old names in a future
-release so please take the minute or two that it will take to remove
-those "32"s. Thanks and I apologize for the hassle this may cause
-people. We would have changed the name to "Bob" but that name's already
-taken by Microsoft... :-)
-
-Why change it? For one thing, not all of the software included in the
-distributions is GNU software, including the Cygwin library itself. So
-calling the project "GNU-Win32" has always been a bit of a misnomer. In
-addition, we think that calling the tools the "Cygwin tools" that use
-the "Cygwin library" will be less confusing to people.
-
-Also notice that we are now on the spiffy new sourceware.cygnus.com
-web/ftp site. The old address will work for some unknown period of
-time (hopefully at least until we get all of the mirrors adjusted).
-
-@subsection Changes in specific tools:
-
-The latest public EGCS release is now the basis for the compiler used
-in Cygwin distributions. As a result, EGCS 1.1 is the compiler in this
-release, with a few additional x86/Cygwin-related patches.
-
-Those of you who are more interested in native Windows development than
-in porting Unix programs will be glad to know that a new gcc flag
-"-mno-cygwin" will link in the latest Mingw32 libs and produce an
-executable that does not use Cygwin.
-
-All of the other development tools have been updated to their latest
-versions. The linker (ld) includes many important bug fixes. It is now
-possible to safely strip a DLL with a .reloc section. The windres
-resource compiler is significantly improved.
-
-Beta 20 also includes upgrades to a number of packages: ash-0.3.2-4,
-bash 2.02.1, grep-2.2, ncurses 4.2, and less 332. We have added bzip2
-0.9.0 to the distribution. And you'll now find that the df utility
-has joined its other friends from the fileutils package.
-
-The sh executable is still ash from the Debian Linux distribution but no
-longer has the problematic quoting bug that was present in the Beta 19
-release. Control-Cs in the bash shell no longer kill background tasks.
-
-Tcl/tk are upgraded to version 8.1a2 (with additional patches).
-Compatible versions of tix and itcl are included. These all include
-Cygwin-compatible configury files so you can do a Unix-style build of
-the Win32 ports of tcl/tk. expect has been upgraded to 5.26 with some
-additional Cygwin patches.
-
-In response to customer requests and feedback, Cygnus has developed a
-better graphical front end to GDB than GDBtk or WinGDB. This tcl-based
-GUI is shipping today to customers of the GNUPro Toolkit. The
-instrumentation changes to GDB and the tcl interpreter that was built
-into GDB are part of the GPL'd source base. But the tcl scripts are not
-being made available to the net at this time. For this reason, you will
-only find a command-line version of gdb in this Cygwin release.
-
-DJ Delorie has written a new "cygcheck" program that will print out
-useful information about how your Cygwin environment is set up, what
-DLLs a named executable is loading from where, etc. We hope this will
-make it easier to help diagnose common setup problems.
-
-The ps utility has been upgraded. It now has several options including
-shorter and longer output formats.
-
-@subsection Changes in the Cygwin API (cygwin.dll):
-
-This version of Cygwin is backwards-compatible with the beta 19 release.
-You can use the new "cygwin1.dll" with your old B19-compiled executables
-if you move the old "cygwinb19.dll" out of the way and install a copy
-of "cygwin1.dll" as "cygwinb19.dll".
-
-Quite a lot of the Cygwin internals have been rewritten or modified to
-address various issues. If you have a question about specific changes,
-the winsup/ChangeLog file in the development tools sources lists all
-changes made to the DLL over the last three years. Following are a few
-highlights:
-
-We are now using a new versioning scheme for Cygwin. There is now a
-separate version number for the DLL, the API, the shared memory region
-interfaces, and the registry interface. This will hopefully make it
-easier for multiple Cygwin toolsets to coexist in one user environment.
-
-Windows 98 is now supported (it is like Windows 95 from Cygwin's
-perspective). We still recommend upgrading to Windows NT.
-
-While there is still a lot left to do in improving Cygwin's runtime
-performance, we have put some effort into this prior to the B20 release.
-Hopefully you will find that the latest version of Cygwin is faster than
-ever. In addition, we have plugged several nasty handle leaks
-associated with opening/closing files and with using ttys.
-
-The lseek call now uses WriteFile to fill gaps with zeros whenever a
-write is done past an EOF, rather than leaving "undefined" data as Win32
-specifies.
-
-Significant work has been done to improve the Cygwin header files.
-
-The Cygwin Support for Unix-style serial I/O is much improved.
-
-Path handling has had another round of fixes/rewrites. We no longer use
-NT Extended Attributes by default for storing Unix permissions/execute
-status because the file NT creates on FAT partitions is not scalable to
-thousands of files (everything slows to a crawl).
-
-Signal handling has also gotten a fair amount of attention.
-Unfortunately, there are still some problems combining itimers and
-Windows 9x.
-
-The number of ttys has been upped from 16 to 128.
-
-New API calls included in the DLL: sethostent, endhostent.
-
-As mentioned earlier, all cygwin32_-prefixed functions are now exported
-with a cygwin_ prefix instead. Please adjust your code to call the
-newly named functions.
-
-reads of `slow' devices are now correctly interrupted by signals, i.e.
-a read will receive an EINTR.
