  • upgraded the nginx core to 1.15.8.
  • change: we now enable the GC64 mode by default in our bundled LuaJIT build for x86_64 architectures; this can be disabled using --without-luajit-gc64. Thanks Thibault Charbonnier for the patch.
  • feature: bundled the lua-tablepool library.
  • feature: bundled the lua-resty-signal library. Thanks OpenResty Inc. for supporting this work.
  • feature: bundled the lua-resty-shell library. Thanks OpenResty Inc. for supporting this work.
  • feature: ./configure: added new options --without-stream_ssl_module and --without-stream.
  • feature: ./configure: added support for the -h option.
  • feature: ./configure: support @rpath placeholder in OS X. Thanks Datong Sun for the patch.
  • feature: updated the socket_cloexec patches to support the ngx.pipe API. Thanks OpenResty Inc. for supporting this work and spacewander for the development of the patch.
  • win32: upgraded OpenSSL to 1.1.0j.
  • bugfix: nginx did not destroy the cycle memory pool before the daemon process exits. Thanks Yuansheng Wang for the patch.
  • bugfix: win32/win64: the error log buffer size was merely 2048 bytes, and is now updated to 4096 bytes.
  • resty-doc indexes: skipped nginx's njs docs due to the use of special xml tags.
  • upgraded ngx_lua to 0.10.15.
    • feature: added support for ARM64 (Aarch64). Thanks Cloudflare for sponsoring this work. Thanks Dejiang Zhu and Zexuan Luo for the development of the patch.
    • feature: implemented the lua_load_resty_core directive which loads resty.core by default. Thanks Thibault Charbonnier for the patch.

    • feature: implemented a new lua_sa_restart directive, which sets the SA_RESTART flag on nginx workers signal dispositions. Thanks Thibault Charbonnier for the patch.
    • feature: implemented the tcpsock:receiveany() upstream cosocket API. Thanks spacewander for the patch.
    • feature: added support for the nginx builtin Link header, which allows for specifying multiple values for this header. Thanks tokers and Thibault Charbonnier for the patch.

    • change: we now avoid running init_by_lua* in signaller processes and when testing the nginx configuration. Thanks spacewander for the patch.
    • change: we now print an alert when a non openresty-specific version of LuaJIT is detected since many optimizations would be missing. Thanks Thibault Charbonnier for the patch.
    • change: we now print a warning when writing to the Lua global variable _G.
    • change: we now avoid generating the Content-Type response header when getting all response headers. Thanks spacewander for the patch.

    • bugfix: ngx.process: type() didn't return 'master' in master process. Thanks spacewander for the patch.
    • bugfix: tcpsock:setkeepalive(): worker processes might take too long to gracefully shutdown when the keep alive connections take a long max idle time. Thanks Dejiang Zhu for the patch.
    • bugfix: setting the request "Host" header should clear any existing cached $host variable so that subsequent reads return the expected result.
    • bugfix: inlined Lua code snippets in nginx.conf failed to use the Lua source checksum as part of the Lua code cache key.
    • bugfix: silenced -Wcast-function-type warnings, allowing for compilation with gcc8. Thanks Alessandro Ghedini for the patch.
