- HTTP/2 smoother and lower memory use (in general)
- HTTP/2 tuning to better handle aggressive client initial requests
- reduce memory footprint; workaround poor glibc behavior; jemalloc is better
- mod_magnet lua performance improvements
- mod_dirlisting performance improvements and new caching option
- memory constraints for extreme edge cases in mod_dirlisting, mod_ssi, mod_webdav
- connect(), write(), read() time limits on backends (separate from client timeouts)
- lighttpd restarts if large discontinuity in time occurs (embedded systems)
- RFC7233 Range support for all non-streaming responses, not only static files
- connect() to backend now has default 8 second timeout (configurable)
