13.1.6:
2        * Modify testcompile.sh to remove 'smatch' and use 'clang'
3          instead.
4        * Fix compile problems with clang.
5        * Modify testcompile.sh to remove 'uno' and use 'cppcheck'
6          for static checking
7        * Move AC_CHECK_FUNCS( getnameinfo getaddrinfo ) behind
8          the check for libsocket to have them found on Solaris
9        * Fix IPv4-only bug in bind_addr use in retry_connect()
10        * Add more debug code in connect_port()
11
123.1.5 (26-03-2015):
13        * Fix IPv6 issue with portcheck (need to be able to specify
14          IPv6 interfaces).
15        * Fix minor issues with bugs in testing code
16        * Add command line option '--server-host' to set the log server
17        * In samhain.startLinux.in start script template, add code to read
18          options from /etc/sysconfig/${NAME} for RedHat
19
203.1.4 (17-02-2015):
21        * Add non-existent file to the regression test config
22        * Fix erroneous call to sh_hash_init when a missing file
23          is specified in the configuration
24        * Fix buffer allocation for getgrnam_r for large groups
25          (problem reported by Sergio B)
26        * Search RPM in $HOME/rpmbuild if test -d _topdir fails (CentOS
27          recommends '%(echo $HOME)/topdir', reported by E. Taft)
28
293.1.3 (01-11-2014):
30        * Remove initgroups() from the popen call in unix entropy gatherer

36        * Allow multiple exclusions for SUID check

38        * Add overflow check in minilzo.c (but the potential integer
39          overflow [CVE-2014-4607,LMS-2014-06-16-1] is irrelevant anyway
40          because the function is never used on external data).
41        * Fixed a minor bug in exepack_fill.c that was unearthed by the minilzo
42          overflow check (the required buffer length information for the check
43          wasn't provided)
44        * Fixed incorrect logic in setting the ALLIGNORE flag (more specific
45          directory / file directives were ignored)
46        * Fix for tickets #358 (repetitive lstat warning about deleted
47          directory) and #359 (reporting of deleted/added top level directory)

51        * Disable inline asm on Cygwin (issue reported by Erik)

82          by isquish)
