Shortly after the release of EPICS R3.14.9 I plan to release ASYN
version 4.7. If you have any outstanding issues that you'd like to
have addressed (or better yet have dealt with yourself) please send
them to me as soon as possible.
Here are the salient points from the release notes:
drvAsynSerialPort
Clean up operation on POSIX/termios systems (everything but vxWorks).
The old mechanism was prone to polling during read operations rather
than using the termios read timeout mechanism.
devGpib
asynRecord sets line-buffering on trace file.
drvGsIP488.c
Clean up dangling 'default' statement.
devGpib
Fixed error in GPIBACMD operations.
linuxGpib
Patches from Gasper Jansa to improve option handling.
devEpics
Fixed null pointer dereference for all device support when SCAN=I/O
Intr and asyn port could not be found.
asynRecord
Fixed buffer overflow error when NRRD>40 and IFMT=ASCII.
asynGpib
Read method now sets return status and *eomReason properly.
drvAsynIPPort/drvAsynSerialPort
*eomReason now set to ASYN_EOM_CNT when read count has been satisfied.
Add support for UDP broadcasts. Specify "UDP*" and the network
broadcast address in the port configuration command:

drvAsynIPPortConfigure("L0", "192.168.1.255:1234 UDP*", 0, 0, 0)
drvAsynSerialPort
Full support for new timeout semantics (timeout<0 means "wait forever
for characters to arrive", timeout=0 means "return characters
immediately available", timeout>0 means "return a timeout status if
no characters are received within the specified number of seconds").
