HHVM 4.162 is released! 4.159 - 4.161 remain supported, as do the 4.128 and 4.153 LTS releases.

Highlights

• Autocomplete improvements to:
  • parent::__construct
  • the first keyword (e.g. the visibility keyword on a method) in the body of a class, interface, or trait
  • implements and extends
• Supports type refinements for readonly expressions
• A Hack property is now considered as a Field instead of a Property in an IDE
• Adds a lint rule for invalid XHP class enum values
• Passing an \Error as the $previous argument to the \Error constructor does not violate an internal typed property anymore. The argument to the constructor has/had the ?\Throwable type, but the $throwable->previous property had the ?\Exception type. Depending on the value of hhvm.check_prop_type_hints key in your configuration, this violation used to trigger a warning (the default), throw an \Error, or do nothing.

Breaking Changes

• Added stricter types for Exception, Error, and Throwable methods and properties
