-----BEGIN PGP SIGNED MESSAGE-----
A new release of readline and libreadline6, 5.2-2, is available for
experimental use, replacing 5.2-1. 5.1-5 remains the current version.
This is a new stable upstream release. However, a bug has reported
against single-line prompts that use invisible characters, which I still
have not found a root cause for. This release adds the same workaround
hack that 5.1-5 was using, but it is possible that I might yet be able to
fix the bug for good. It is also possible that there might be upstream
bug fixes in the near future, if previous bash release patterns remain
true. 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; and
nobody did so with the 5.2-1 release).
A short list of upstream changes since 5.1 is attached. See also
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.
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.
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:
If you want to make a point or ask a question the Cygwin mailing list is
the appropriate place.
