Update to 0.9.19. Changes:
- EasyBindings inclusion! EasyBindings provide simple C++, Python,
Perl, Ruby, and Lua bindings for using libprelude. They are still
considered experimental, thus you need to use (--enable-easy-bindings)
to activate them. Thanks to Sebastien Tricaud <toady@inl.fr> and
Pierre Chifflier <p.chifflier@inl.fr> for their contribution to this
project!
- Use automake/autoconf for building/installing Python extension.
- Fix 0.9.18 regression (alert created with empty CreateTime).
- Implement reference counting for the idmef-criteria and
prelude-connection API.
- Automatic casting when setting IDMEF Value to a field that is of
different type. Until now, if an user tried to set a path of a
specific type with an idmef_value_t object containing another type,
idmef_path_set() would return an error.
- Various bug fixes.
