HHVM 4.150 is released! This release marks the end of support of 4.144; 4.145 – 4.149 remain supported, as do the 4.102 and 4.128 LTS releases.

Highlights

• The ENT_HTML5 constant is now recognized by the typechecker
• Added getSslCertCn(), getSslCertSan(), getSslCertExtensions(), and isSslCertValidationEnforced() to AsyncMysqlResult and AsyncMysqlConnection
• Added $server_cert_values parameter to AsyncMysqlClient::connect(), which contains comma separated values that are matched against the existing $cserver_cert_extensions parameter when verifying the certificate.
• class_implements(), class_parents(), and class_uses() are now marked as pure
• If a function is marked as returning mixed but returns without a value, LSP-based IDEs such as VSCode will now suggest void or Awaitable<void> return types
• LSP-based IDEs will now show Vector/Map/Set documentation comments on hover for literals, not just the types
• LSP-based IDE hover information for shape elements will now show information type information the specific element, not the shape as a whole
• HH\Readonly\Shapes now includes typechecker definitions

Breaking Changes

• AsyncMysqlClient::adoptConnection() has been removed.
• It is now a type error to use meth_caller() on methods that return a readonly object; previously, this would be a runtime error. This is due to technical limitations of the current implementation.
• If a memoized function is called from a context that does not have the write_globals capability, a more specific error is raised based on the write or passing of the return value (if mutable), instead of always when the function is called. This may change necessary fixme codes from 4461 (“a memoized function is called”) to 4459 (“A global variable is written”).
• Removed `HH\class_get_class_name()
