Release Notes: This release fixes a number of bugs in the HTTP layer as well as signal processing.
Release Notes: This release fixed several memory leaks in the HTTP layer, fixed signal handling for multi-threaded applications, and fixed issues with the timer cache when leaving or entering the event loop.
Release Notes: This release contains several small bugfixes, including epoll timeouts larger than 35 minutes on older Linux kernels and portability improvements for Windows and IRIX.
Release Notes: Several new APIs have been introduced (event_base_new, event_reinit, event_loopbreak, etc.). RPC structures can now use 32-bit structure identifiers. The performance of the Windows backend has been improved. There are additional bug and correctness fixes.
Release Notes: This release contains a new RPC subsystem that makes it easy to write distributed servers and clients. Almost everything is documented via Doxygen now. There have been a bunch of fixes and improvements to evdns and evhttp. Libevent now builds two additional libraries: libevent_core (containing only the event core) and libevent_extras (contained evdns, evhttp, and evrpc). Performance was slightly improved due to using a heap instead of red-black trees for timeouts. Finally, Solaris' event ports are better supported.
Release Notes: This release contains mostly reliability and portability fixes. Several problems on Solaris were fixed, the HTTP Server now includes a Date header by default, and several memory leaks in the HTTP and DNS layer were fixed.
Release Notes: Bugs in libevent's HTTP layer were fixed.
Release Notes: Small bug and portability fixes.
Release Notes: Signals may now be used in multi-threaded applications.
Release Notes: Support for running a DNS server was added along with IPv6 name lookups and chunked transfer encoding for HTTP/1.1. A fix was provided for a DoS in the DNS system.
