Folks,

asyn R4-15 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 now also available via the APS Subversion repository here:
https://svn.aps.anl.gov/epics/asyn/

This is from the release notes:
*********************************************

vxi11
The third argument to the vxi11Configure command is now a bit-map. The least significant bit (value 0x1) remains the 'recover with IFC' control. The next-to-least significant bit (value 0x2) when set will cause all devices to be locked when a connection is made. This allows for cooperative exclusive access to devices.

asynManager
Fixed memory leak in lockPort() when an error occured, was not calling freeAsynUser(). Thanks to Andrew Starritt for finding this.

devEpics
Bug fix for devAsynInt32 and devAsynFloat64: it was not freeing the mutex in processAiAverage if numAverage==0, i.e. there had been no callbacks from the driver since the record last processed. This would hang the next thread that tried to take the mutex, typically the driver callback thread.

Bug fix for devAsynXXXArray: it was calling drvUserCreate in the port driver even if there was no userParam in the link, which could crash the driver.

Many files

Changes to allow building dynamically on WIN32 (i.e. making DLLs).

Makefiles
Changes to allow building on Cygwin 1.7.x or 1.5.x; replaced rpc with $(CYGWIN_RPC_LIB), which allows it to link with rpc on 1.5.x and tirpc on 1.7.x.
program was changed to test and demonstrate this.
