HHVM 4.67 is released! This release marks the end of support for 4.60; HHVM 4.61–4.66 remain supported, as do the 4.32 and 4.56 LTS releases.

Highlights

  • Server stats are now cleared after warmup, to reduce noise from requests that should be unrepresentative.
  • Runtime type errors now consistently say varray or darray as appropriate, instead of just array.

Breaking Changes

  • An exception is now thrown when a file contains top-level code.
  • HackC will no longer emit top-level code outside of the debugger.
  • Backticks are no longer parsed as quotation separators; they were previously equivalent to double quotes.
  • (array) casts are now disabled in the runtime.
