Update to 7.3:

Release 7.3 28-Aug-07
---------------------

Most changes are bug fixes. Some that are not:

1. There is some support for Perl 5.10's experimental "backtracking control
   verbs" such as (*PRUNE).

2. UTF-8 checking is now as per RFC 3629 instead of RFC 2279; this is more
   restrictive in the strings it accepts.

3. Checking for potential integer overflow has been made more dynamic, and as a
   consequence there is no longer a hard limit on the size of a subpattern that
   has a limited repeat count.

4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec()
   no longer advance by two characters instead of one when an unanchored match
   fails at CRLF if there are explicit CR or LF matches within the pattern.
   This gets rid of some anomalous effects that previously occurred.

5. Some PCRE-specific settings for varying the newline options at the start of
   a pattern have been added.

Update to 7.2:

Release 7.2 19-Jun-07
---------------------

WARNING: saved patterns that were compiled by earlier versions of PCRE must be
recompiled for use with 7.2 (necessitated by the addition of \K, \h, \H, \v,
and \V).

Correction to the notes for 7.1: the note about shared libraries for Windows is
wrong. Previously, three libraries were built, but each could function
independently. For example, the pcreposix library also included all the
functions from the basic pcre library. The change is that the three libraries
are no longer independent. They are like the Unix libraries. To use the
pcreposix functions, for example, you need to link with both the pcreposix and
the basic pcre library.

Some more features from Perl 5.10 have been added:

  (?-n) and (?+n) relative references for recursion and subroutines.

  (?(-n) and (?(+n) relative references as conditions.

  \k{name} and \g{name} are synonyms for \k<name>.

  \K to reset the start of the matched string; for example, (foo)\Kbar
  matches bar preceded by foo, but only sets bar as the matched string.

  (?| introduces a group where the capturing parentheses in each alternative
  start from the same number; for example, (?|(abc)|(xyz)) sets capturing
  parentheses number 1 in both cases.

  \h, \H, \v, \V match horizontal and vertical whitespace, respectively.

Log message:
Fix pcre-config to always output the rpath for ${prefix}/lib based
on COMPILER_RPATH_FLAG. Before it hard-wired Solaris and *BSD, now
it works everywhere. Bump revision.

Log message:
Remove dead MASTERS_SITES. From Zafer Aydogan.

Update to 7.1:

Release 7.1 24-Apr-07
---------------------

There is only one new feature in this release: a linebreak setting of
PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which
recognizes only CRLF, CR, and LF as linebreaks.

A few bugs are fixed (see ChangeLog for details), but the major change is a
complete re-implementation of the build system. This now has full Autotools
support and so is now "standard" in some sense. It should help with \ 
compiling
PCRE in a wide variety of environments.

NOTE: when building shared libraries for Windows, three dlls are now built,
called libpcre, libpcreposix, and libpcrecpp. Previously, everything was
included in a single dll.

Another important change is that the dftables auxiliary program is no longer
compiled and run at "make" time by default. Instead, a default set of \ 
character
tables (assuming ASCII coding) is used. If you want to use dftables to generate
the character tables as previously, add --enable-rebuild-chartables to the
"configure" command. You must do this if you are compiling PCRE to run on a
system that uses EBCDIC code.

There is a discussion about character tables in the README file. The default is
not to use dftables so that that there is no problem when cross-compiling.

Log message:
Update to 7.0:

Release 7.0 23-Nov-06
---------------------

This release has a new major number because there have been some internal
upheavals to facilitate the addition of new optimizations and other facilities,
and to make subsequent maintenance and extension easier. Compilation is likely
to be a bit slower, but there should be no major effect on runtime performance.
Previously compiled patterns are NOT upwards compatible with this release. If
you have saved compiled patterns from a previous release, you will have to
re-compile them. Important changes that are visible to users are:

1. The Unicode property tables have been updated to Unicode 5.0.0, which adds
   some more scripts.

2. The option PCRE_NEWLINE_ANY causes PCRE to recognize any Unicode newline
   sequence as a newline.

3. The \R escape matches a single Unicode newline sequence as a single unit.

4. New features that will appear in Perl 5.10 are now in PCRE. These include
   alternative Perl syntax for named parentheses, and Perl syntax for
   recursion.

5. The C++ wrapper interface has been extended by the addition of a
   QuoteMeta function and the ability to allow copy construction and
   assignment.

Log message:
DESTDIR support.

Log message:
Fixed "test ==" in the configure script and a spelling mistake. It's
PKGCONFIG_OVERRIDE, not PKG_CONFIG_OVERRIDE.

Log message:
Before including sys/resource.h on DragonFly, sys/time.h is needed.

Log message:
Update to 6.7:

Release 6.7 04-Jul-06
---------------------

The main additions to this release are the ability to use the same name for
multiple sets of parentheses, and support for CRLF line endings in both the
library and pcregrep (and in pcretest for testing).

Thanks to Ian Taylor, the stack usage for many kinds of pattern has been
significantly reduced for certain subject strings.
