HHVM 4.54 is released! This release marks the end of support for 4.48; HHVM 4.49–4.53 remain supported, as do the 4.8 and 4.32 LTS releases.
inoutparameters on async functions now only raise a parse error, instead of a parse error and a NastCheck error.
- improved accuracy of line numbers for errors or backtraces within
ignored_fixme_codes(errors that can not be suppresed) hack option is no longer respected for HHI files; this allows projects to use a stricter list than is compatible with builtins.
- If using CLI server mode, a warning is now logged if the CLI client does not
recognize a command sent to the CLI server. We strongly recommend using
hhvm.check_cli_client_commands=2INI setting to raise an error instead: these warnings indicate a bug in HHVM, and can not be safely recovered from. If you see this warning, please file a bug report. It can also be set to
0to disable the warnings. Any value other than
2leads to undefined behavior in this error case.
- Increased the efficiency of
idx()and array access on empty containers.
- Containers are now more consistently checked for valid
arraykeys; this behavior can be enabled on old releases with the
hhvm.check_cli_client_commandsINI setting will default to
2(error) in a future release.
