All major functionality that will be in R3.13 is now in place. It has been

Task Priorities</H3>
The priority of the channel access client for database links was changed
from 100 to 68, which makes it lower than all scan tasks but higher than
the sequencer or any channel access tasks.

This was changed to print numbers with precision&lt;=8 and magnitude &lt;1e16
in fixed format with up to 3 digits after the decimal point. As an example
