Folks,

asyn R4-20 is now available.  Links to the new documentation, release notes and tar file can be found here:
http://www.aps.anl.gov/epics/modules/soft/asyn/

asyn is also available via the APS Subversion repository here:
https://svn.aps.anl.gov/epics/asyn/

This is from the release notes:
*********************************************
- asynManager
Fixed a bug that caused a deadlock if pasynManager->lockPort was called multiple times without calling pasynManager->unlockPort in between. Thanks to Sebastian Marsching from "aquenos GmbH" for this fix. 

- devEpics
Added support for setting the record timestamp from the driver, using a new field, pasynUser->timeStamp. The driver can set this field in read and callback operations. 

Fixed a long-standing bug in devAsynXXXArray support for input waveform records with SCAN=I/O Intr. The data were being copied to the record without using dbScanLock. This meant that the data could change while the record was processing.

Changed the "ring buffer overflow" messages from "ASYN_TRACE_ERROR" to "ASYN_TRACEIO_DEVICE", so they do not appear by default. These messages are not really errors, but warnings that record processing it not keeping up with the rate of driver callbacks for records with SCAN=I/O Intr.
