ChangeLog for PCRE
------------------
Note that the PCRE 8.xx series (PCRE1) is now in a bugfix-only state. All
development is happening in the PCRE2 10.xx series.
Note that the PCRE 8.xx series (PCRE1) is now at end of life. All development
is happening in the PCRE2 10.xx series.
Version 8.45 15-June-2021
-------------------------
This is the final release of PCRE1. A few minor tidies are included.
1. CMakeLists.txt has two user-supplied patches applied, one to allow for the
setting of MODULE_PATH, and the other to support the generation of pcre-config
file and libpcre*.pc files.
2. There was a memory leak if a compile error occurred when there were more
than 20 named groups (Bugzilla #2613).
3. Fixed some typos in code and documentation.
4. Fixed a small (*MARK) bug in the interpreter (Bugzilla #2771).
