HHVM 4.53 is released! This release marks the end of support for 4.47; HHVM 4.48–4.52 remain supported, as do the 4.8 and 4.32 LTS releases.
- We now build binary packages for Ubuntu 19.10. Packages for Ubuntu 20.04 should become available after its final release.
- The type-checker now provides more helpful error messages when cyclic shape type aliases are detected, pointing out both the invalid type alias and the cause of the cycle.
