HHVM 3.29.1 和 3.27.4 发布了，这两个版本均包含 Bugfix 和功能改进：

3.29.1

• Fix reversed assignment when lambdas have multiple inout parameters

• This release is available for Ubuntu 18.10 Cosmic

• Significantly reduced lock contention when not running in repo-authoritative mode

• Fix incorrect results for experimental HSL regex when combined with offset capture

• Support building on systems where $PATH includes spaces

3.27.4

• Fix reversed assignment when lambdas have multiple inout parameters

• Support stream_await() on FDs when using CLI server (included in 3.29.0)

• stream_await() will throw an InvalidOperationException if called on an unawaitable file descriptor. This includes actual on-disk files on Linux, as they are not supported by epoll. We recommend that callers attempt to stream_await(), and handle this exception if neccessary. The stream metadata can not be used to identify whether or not a stream is awaitable - for example, hhvm foo.php has an awaitable STDIN, but hhvm foo.php < myfile has an awaitable STDIN on MacOS (kqueue) but not on Linux (epoll). In prior releases, behavior varied; the most common result was writing an error to STDOUT, and the awaitable not resolving, with request timeout eventually being reached (included in 3.29.0)

开发团队表示，对最后一个 issue 的修复在技术上属于 BC break（破话了向后兼容性，backward compatibility），但还是将其引入了该版本中，不然项目会出现更大的问题。
