That's it! More than 350,000 downloads later, Portal: Prelude 1.1.5 (final) is released!
This new version is shipped with more than 115 bug fixes, improvements and additions (since 1.0.0). We know everything's still not perfect (voices, grammar, difficulty), but we believe we put enough work in this mod and thus, this version should be considered final (except if something really bad happens). Warning! Savegames are NOT compatible. Your progress with chapters unlocking is saved, but not savegames.
Also, there was so much changes to the game files that it's pretty much useless to release a cumulative patch from 1.1.0 to 1.1.5. It would be nearly as big as the complete installer itself. Please note that there's nothing worth redownloading the whole mod again if you already downloaded it, as it's mostly graphical improvements, optimizations and minor bug fixes.
