bugfix: init_worker_by_lua* would conflict with some other nginx C modules (like ngx_proxy) when their merge_loc_conf callbacks (or alike) produce side-effects in cf->cycle. thanks Ruoshan Huang for the report.
doc: typo fix.
doc: bumped version to 0.9.11; also claimed that we work with nginx 1.7.4.
bugfix: compilation failed with nginx 0.9.x.
bugfix: compilation failed with nginx 1.3.6 or older. this regression had appeared in the v0.9.11 release.
bugfix: the "tcp_nodelay" directive configuration was not honored by upstream TCP cosockets, which could lead to extra delays for small messages. thanks Shun Zhang for reporting this issue.
tests: fixed a case for raw req socket to reflect recent changes in the debugging logs for tcp_nodelay.
bugfix: create_loc_conf did not return NULL on error.
