FreeCol 0.9.4 has been released.
Several serious bugs, including a memory or reference leak that caused 0.9.3 to slow to a crawl, have been fixed. A graphical modification (mod) by misiulo adds new graphics for goods and resources. Translations for several languages have been considerably improved.
