<h4>Breakpoint tables</h4>
<p>Some sites may be using breakpoint tables that are not monotonic in one
direction. In R3.14.9 both axes of a breaktable had to be monotonic; a table
will not be loaded if either the raw or engineering values change direction.
There are situations where this check is too strict however, so a new variable
named <tt>dbBptNotMonotonic</tt> has been added that disables this check if its
value is non-zero.</p>
<p>Breakpoint tables are often included in an IOC's .dbd file, but they can also
be loaded from a .db file (although VDCT will probably not understand them).
Since there is no way to set the above variable inside the <tt>dbExpand</tt>
program that expands out an IOC's .dbd file (which also rejects non-monotonic
breaktables), all applications that use such tables will have to load those
tables separately, using either <tt>dbLoadDatabase</tt> or
<tt>dbLoadRecords</tt>.</p>
<h4>RTEMS on processors with MOTLOAD bootstrap</h4>
<p>Added support for more 'Global Environment Variables'. Documented in
the EPICS/RTEMS tutorial.</p>
