 	* libpri 1.4.10.1 released.  Includes a fix for a regression found in
-	the last few revisions of libpri, but fixed in revision 859 of
-	branches/1.4.  The summary is as follows:
-
-	* q921.c: There are two changes in this commit that are bug fixes for various Q.921 issues found in internal testing.
-
-	Both were exposed/introduced by the TBR4 compliance patch for bug #12861, in changing how retransmissions and in how
-	the transmission queue was maintained.  TX-RX message flow and acknowledgement was severely restricted,
-	since the patch changed the behavior so that pending untransmitted frames would not actually be send until
-	the next RR was received in normal circumstances, or REJ when a reject frame was received.  On busy links,
-	this can severly limit the amount of useful traffic that is sent, and can slow down message transmission.
-
-	Until someone can point out where in Q.921 it is mandated for us to wait for RR frames to start sending
-	untransmitted messages, the first change is to allow us to send untransmitted frames when we receive new
-	I frames as well, with updated N(R).
-
-	The other bug fixed is a situation caused by the restricted traffic flow, if an outside process tries to send
-	an I-frame asynchronous to an RR frame, when the transmit window was previously closed and then opened up but 
-	an RR has not been received yet.  A bug was found with the integration of the old transmit code with the new reject 
-	handling code which caused the new frame to be sent immediately, regardless if there were any pending untransmitted 
-	I-frames in the queue to be sent and causing an out of order I-frame to be sent to the other side.  This bug is 
-	also fixed in this patch.
