HHVM 4.124 is released! This release marks the end of support for 4.118; HHVM 4.120–4.123 remain supported (4.119 was skipped), as do the 4.80 and 4.102 LTS releases.

This release primarily contains improvements to implementation details, and preparatory work for future features/changes.

Future Changes
