This version of EPICS Base has not been released yet.
The epicsReadline code has been reorganized to allow the commandline history editor to be disabled at runtime. The EPICS_COMMANDLINE_LIBRARY build setting still selects the preferred editor, but the new IOCSH_HISTEDIT_DISABLE environment variable can be set at runtime to disable history editing and make the IOC or other program use the basic editor instead. This is useful when starting and controlling an IOC from another program through its stdin and stdout streams since history editors often insert invisible escape codes into the stdout stream, making it hard to parse.
Added a new macro callbackGetPriority(prio, callback) to the callback.h header and removed the need for dbScan.c to reach into the internals of its CALLBACK objects.
