"  - complete overhaul of this package, with update to 2.7.5.

  - ruleset update to 2.2.8-0-g0f07cbb.

  - new configuration framework private to mod_security2:
    /etc/apache2/conf.d/mod_security2.conf loads
    /usr/share/apache2-mod_security2/rules/modsecurity_crs_1
    0_setup.conf, then /etc/apache2/mod_security2.d/*.conf ,
    as set up based on advice in
    /etc/apache2/conf.d/mod_security2.conf Your
    configuration starting point is
    /etc/apache2/conf.d/mod_security2.conf

  - !!! Please note that mod_unique_id is needed for
    mod_security2 to run!

  - modsecurity-apache_2.7.5-build_fix_pcre.diff changes
    erroneaous linker parameter, preventing rpath in shared
    object.

  - fixes contained for the following bugs :

  - CVE-2009-5031, CVE-2012-2751 [bnc#768293] request
    parameter handling

  - [bnc#768293] multi-part bypass, minor threat

  - CVE-2013-1915 [bnc#813190] XML external entity
    vulnerability

  - CVE-2012-4528 [bnc#789393] rule bypass

  - CVE-2013-2765 [bnc#822664] NULL pointer dereference
    crash

  - new from 2.5.9 to 2.7.5, only major changes :

  - GPLv2 replaced by Apache License v2

  - rules are not part of the source tarball any longer, but
    maintaned upstream externally, and included in this
    package.

  - documentation was externalized to a wiki. Package
    contains the FAQ and the reference manual in html form.

  - renamed the term 'Encryption' in directives that
    actually refer to hashes. See CHANGES file for more
    details.

  - new directive SecXmlExternalEntity, default off

  - byte conversion issues on s390x when logging fixed.

  - many small issues fixed that were discovered by a
    Coverity scanner

  - updated reference manual

  - wrong time calculation when logging for some timezones
    fixed.

  - replaced time-measuring mechanism with finer granularity
    for measured request/answer phases. (Stopwatch remains
    for compat.)

  - cookie parser memory leak fix

  - parsing of quoted strings in multipart
    Content-Disposition headers fixed.

  - SDBM deadlock fix

  - @rsub memory leak fix

  - cookie separator code improvements

  - build failure fixes

  - compile time option --enable-htaccess-config (set)"
