A new release of readline and libreadline6, 5.2-1, is available for
experimental use.  5.1-5 remains the current version.

NEWS:
=====
This is an upstream release candidate, and hence experimental.  It is
possible that there are still bugs that will be fixed between this beta
and the final upstream release of 5.2.  Additionally, this version is not
strictly binary compatible with readline 5.1; it removes a cygwin-specific
entry point that bash 3.0 (but not bash 3.1) depended on.  Now that bash
3.0 is no longer available from the cygwin mirrors, I felt it safe to drop
that cygwin-specific patch.  Although it is unlikely that any other
package depended on this entry point, I need to know now if this decision
was not wise, in which case I will create libreadline7 when promoting
readline 5.2 to current, leaving libreadline6 to preserve the entry point;
but I will only do this if someone can demonstrate why it is needed (hint,
you would have to mention the entry point by name to show you know what
you are talking about).

The upstream maintainer claims that this version fixes some prompt display
bugs when using non-printing escape sequences with a single-line prompt.
I have not verified this, but hope that this is the case.

DESCRIPTION:
============
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.

libreadline6 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 6 in libreadline6
distinguishes incompatible API changes made to the prior libreadline4 and
libreadline5 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.

UPDATE:
=======
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 'libreadline6'
from the 'Base' category (it should already be selected), or 'readline' in
the 'Devel' category.  Be sure that you do not have any cygwin programs
running during the upgrade.  You will need to use the 'Exp' radio button
since this release is experimental.

DOWNLOAD:
=========
Note that downloads from sources.redhat.com (aka 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:

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