HHVM 4.82 is released! This release marks the end of support for 4.76; HHVM 4.77–4.81 remain supported, as does the 4.56 LTS release.

Highlights

• AsyncMysqlQueryResults has the new method dictRowsTyped(): vec<dict<string, arraykey>>.
• Improved several typechecker error messages for incompatible method overrides, e.g. when an override has more mandatory arguments.

Breaking Changes

• array_fill_keys() will now throw an InvalidArgumentException if the first argument is not a Container; in previous versions, HHVM would return false. With this change, array_fill_keys() now only returns darrays.
• improved correctness when type constants are accessed via inferred union or intersection types. This can both lead to fewer incorrect type checker errors, but also additional correct type checker errors.
