This release adds a new 'UPGRADE' state message and a GUI indicator message triggered if the installed fpnd version is too old or otherwise incompatible with the running FreePN infrastructure node version. The latest version of fpnd adds the running version to the initial "node announce" message, which is checked against the minimum compatible version (currently 0.9.6) and then accepted if the user node version is greater-than or equal-to the minimum "base" version.
See the README file for more information.
