commit
e44ef375ee
@ -76,6 +76,7 @@ Changes in current version:
|
||||
o fix a bug in which bufferevent_write_buffer would not schedule a write event
|
||||
o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure
|
||||
o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents
|
||||
o convert evhttp_connection to use bufferevents.
|
||||
|
||||
Changes in 1.4.0:
|
||||
o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr.
