@ -75,16 +75,26 @@ ELinks 0.12pre2.GIT now:
To be released as 0.12pre3, 0.12rc1, or even 0.12.0. This branch also
includes the changes listed under ``ELinks 0.11.5.GIT'' below.
Incompatibilities:
* bug 1060: Regexp searching now requires the TRE library.
Other changes:
* critical: Fix assertion failure if IMG/@usemap refers to a different
file.
* Preserve newlines in hidden input fields, and submit them as CRLF.
Previously, they could turn into spaces or disappear entirely.
* Perl scripts can use modules that dynamically load C libraries, like
XML::LibXML::SAX does.
* bug 153: Preserve Unicode characters in XBEL bookmark files.
However, Unicode in URIs (really IRIs) does not work reliably yet;
this is being tracked as bug 1066.
* bug 885: Convert xterm titles to ISO-8859-1 by default, but add an
option to disable this. When removing control characters from a
title, note the charset. Don't truncate titles to the width of the
terminal.
* bug 1061: Correctly truncate UTF-8 titles in the tab bar.
* enhancement: Updated ISO 8859-7, ISO 8859-16, KOI8-R, and MacRoman.
