1.So Chaos;Child just came out. It is the spiritual successor to Chaos;head also developed by 5pb games. Unfortunately there is no PC version, only a PS4 and Vita release. It is still possible to play with emulators however and I think it is worth having.
2.Ataraxia voice patch is out, porting voices as well as BGM from the vita release. Further a full uncensor was made, removing mosaics from all h-content. Find it here (Fate/Hollow Ataraxia Voice Patch)
3. More of an FYI, eden of grisaia 18+ just finished translation. It'll be released after testing.
