From today EOSERV now links to the MariaDB Client Library, in place of the MySQL Client Library. MariaDB provides a connector library that is compatible with MySQL, and released under a more permissive license.
EOSERV has been distributed under the zlib license, however due to being linked to the MySQL Client Library, may be subject to the terms of the GPLv2, which forbids distributing modified versions without also making the source code available.
Any closed-source distributions derived from EOSERV using the MySQL Client Library are encouraged to cease distribution of any release bundled with the MySQL Client Library.
As the sole copyright holder of all of the source code in EOSERV, and exemptions provided by MySQL's FOSS License Exception, I believe that EOSERV 0.6.2b and the main-line code starting from revision 437 onwards are free from the requirements of the GPLv2 and may be re-distributed without the requirement to release your source code, or any other restriction of the GPLv2. I strongly recommend reading the full text of the LGPL for any other requirements on redistributing the libraries bundled with EOSERV.
You may obtain a copy of the MariaDB Client Library from https://downloads.mariadb.org/connector-c/ (2.0 is recommended, not 2.1)
EOSERV 0.6.2 has been re-released as 0.6.2b with no changes other than the replacement of libmysql with libmariadb. You can obtain it from the Downloads page, or check out the source from SVN (svn://eoserv.net/eoserv/tags/0.6.2b).
