OpenResty Released

Johnny Wang , 16 Aug 2021 (created 06 Aug 2021)

We are happy to announce the new formal release,, of the OpenResty web platform based on NGINX and LuaJIT.

Download this version here.

The (portable) source code distribution, the Win32/Win64 binary distributions, and the pre-built binary Linux packages for Ubuntu, Debian, Fedora, CentOS, RHEL, Alpine, OpenSUSE, Amazon Linux are provided on this Download page.

Version Highlights

  • Based on a very recent mainline NGINX core 1.19.9.
  • Many fixes imported from Mike Pall's upstream LuaJIT repository.
  • Introduce a new macro LUAJIT_TEST_FIXED_ORDER for fixed-order traversal of lua tables. This option is disabled by default. It can be enabled by passing the --with-luajit-xcflags LUAJIT_TEST_FIXED_ORDER=1 option to the ./configure command line while building OpenResty from source.
  • When lua failed in requesting memory, instead of graceful shutdown, abort() is called.
  • Now the get_ctx_table supports using the ctx table from caller, and that will reduce the cost of creating a new ctx table.
  • Fixed the bug that the metatable was not cleared when clearing the content of lua table when using lua-tablepool.
  • For a better performance when using lua-tablepool, discard the objects when the pool size is larger than the max_pool_size.
  • Implemented ngx.process API for stream subsystem.
