HHVM 4.111
HHVM 4.111 is released! This release marks the end of support for 4.105; HHVM 4.106–4.110 remain supported, as do the 4.80 and 4.102 LTS releases.
Highlights
- Abstract
context constants
are now allowed by default (in previous HHVM versions, they can be enabled
using the INI option
enable_abstract_context_constants = true). - The typechecker no longer raises an error if the
?->operator is used on an object of a non-nullable type (these calls are safe, even if unnecessary).
Breaking Changes
- The typechecker now raises an error when the same non-abstract method is included in a class via multiple traits. These had already been runtime errors, but not always caught by the typechecker.
- The typechecker now detects more cases when a
Mapis used with a key of an invalid type (e.g.dynamic,null) that would previously only cause runtime errors. - Fixed a bug where the typechecker wouldn’t detect a constructor calling a
method with an uninitialized instance variable:
$this->someMethod($this->uninitializedVar)
