[ANNOUNCEMENT] Updated: [32-bit] libreadline7-6.1.2-4, libreadline-devel-6.1.2-4

A new release of readline, 6.1.2-4, has been uploaded and will soon
reach a mirror near you; leaving the previous version at 6.1.2-3.  This
release only targets the 32-bit build; the 64-bit build of cygwin
remains with newer readline 6.2-1.  I will also be posting a test
version of readline-6.3.8-1 in the near future.

This is a minor rebuild to sort out packaging issues and refresh against
newer cygwin (no source changes).  I have renamed the development
package from 'readline' to 'libreadline-devel', to match the naming
convention already in the 64-bit build.  The 'readline' package is now
obsolete, but still exists to ensure a smooth upgrade path (setup.exe
will automatically suggest that you install libreadline-devel if you had
previously installed the non-essential readline); the essential
'libreadline7' dll package has no change.  I also added a
'readline-debuginfo' package.

Remember, you must not have any bash or /bin/sh instances running when
you upgrade the readline package.  This release requires cygwin-1.7.33-1
or later.  See also the upstream documentation in /usr/share/doc/readline/.

Be aware that an issue with offering libreadline as both a static and
dynamic library has been identified - some functions, such as
rl_function_of_keyseq, cannot work correctly with both library styles
without some additional __declspec decoration in the dynamic case.  This
release caters to static compilation (and packages like bash that use
the problematic functions from dynamic readline have to add a minimal
workaround); so the upcoming readline 6.3 will be dynamic only.

The readline library will read a line from the terminal and return it,
allowing the user to edit the line with emacs or vi editing keys.  It
also allows a history feature, for editing previous entries, making
command line interfaces easier-to-use and more intuitive.

libreadline7 provides the .dlls needed for readline and history
expansion for dynamic linking in other programs, including bash and gdb;
it is required for a minimal cygwin installation.  The 7 in libreadline7
distinguishes incompatible API changes made to the prior libreadline5
and libreadline6 libraries still available on the mirrors. readline
provides the documentation and the static libraries required for static
linking; you should only need it if you plan on compiling an application
that links with -lreadline or -lhistory.

To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your
system. Save it and run setup, answer the questions and pick up
'libreadline7' in the 'Base' category (it should already be selected),
or 'libreadline-devel' in the 'Devel' category.

Note that downloads from cygwin.com aren't allowed due to bandwidth
limitations.  This means that you will need to find a mirror which has
this update, please choose the one nearest to you:

If you want to make a point or ask a question the Cygwin mailing list is
the appropriate place.
