[Hardhats-port-news] GT.M V4.3-001A now available

GT.M V4.3-001A has been released.  This release adds significant new
functionality in the areas of Job Interrupt, alternation in pattern
matching, performance enhancements in the area of M locks, and
additional database tuning parameters.

Since GT.M's security model is to use, and not bypass or subsume, the
security of the underlying operating system, the new Job Interrupt
capability respects OS security (i.e., in order to signal a GT.M
process, the sender must have permission from the OS to send the
signal).  The default behavior of GT.M Job Interrupt provides a "job
examine" functionality, but the underlying mechanism is a more general
mechanism that enables an M process to receive and handle an
asynchronous signal.

Alternation in pattern matching is required to run the VistA
application.  So, if you have been using the V4.3-FT06 version, please
switch to V4.3-001A.

Technical bulletins for the release notes as well as for Job Interrupt
and the new functionality for mupip set journal are also available.

Please download and use the new version, and give feedback.  Thank you
for your continued interest in GT.M.
