Folks,

asyn R4-37 is now available. 

asyn is available on github here:
https://github.com/epics-modules/asyn 

tar and zip files are available here:
https://github.com/epics-modules/asyn/releases 

Soon you will be able to find links to the new documentation and release notes here:
http://www.aps.anl.gov/epics/modules/soft/asyn 

These are from the R4-37 release notes: 

- Added new 64-bit integer support
  - asynDriver adds new asynInt64, asynInt64SyncIO, and asynInt64Array interfaces.
  - asynDriver.h now does the typedef of epicsInt64 and epicsUInt64 when __STDC_VERSION__ < 199901L on EPICS 3.14. 
       This allows the Int64 interfaces to be built as long as the compiler supports the long long and unsigned long long data types.
  - devEpics.dbd is now constructed at build time rather than being a static file. This enables Int64 device support to only be included on EPICS 3.16.1 and later.
   - asynPortDriver adds support for 64-bit integers:
      - New parameter types asynParamInt64 and asynParamInt64Array.
      - New methods setInteger64Param(), getInteger64Param(), readInt64(), writeInt64(), getBounds64(), readInt64Array(), writeInt64Array(), doCallbacksInt64Array().
      - New masks for constructor asynInt64Mask, asynInt64ArrayMask.

- testErrors test application
    Changes to driver, database and medm screens to test the Int64 interfaces. This uses the 64-bit device support which must be commented of out st.cmd if running on EPICS versions prior to 3.16.1.

-  New FTDI driver
    This driver allows much greater control over USB ports for serial communication than the standard Linux /dev/ttyUSBx driver. Thanks to Bruno Martins for this.

- devEpics
    Fixes to only print an error message when the status of a write or read operation changes, not each time there is an error. Thanks to Ben Franksen for this.

- asynRecord
    Fixes to allow changing the HOSTINFO for the asynIPPort driver when the port is not connected. Thanks to Krisztián Löki for this.

- Many files
    Changes to avoid compiler warnings.
