The epicsReadline refactoring work described below unfortunately disabled the +VxWorks implementation of the osdReadline.c API that uses ledlib for command +editing and history. This functionality has now been restored, see Launchpad +bug #1741578.
+ +Constant links can now hold 64-bit integer values, either as scalars or +arrays. Only base 10 is supported by the JSON parser though, the JSON standard +doesn't allow for hexadecimal numbers.
+ +The third-party YAJL library that has been included in libCom for several +years has been upgraded to version 2.1.0 and several bugs fixed. This has an +updated API, requiring any code that uses it to parse its own JSON files to be +modified to match. The changes are mainly that it uses size_t instead +unsigned int for string lengths, but it also uses long long +instead of long for JSON integer values, which was the main motivation +for the upgrade.
+ +The self-tests that YAJL comes with have been imported and are now run as an +EPICS Unit Test program, and the JSON syntax accepted by the parser was extended +to permit trailing commas in both arrays and maps. The difference between the +old and new YAJL APIs can be detected at compile time by looking for the macro +EPICS_YAJL_VERSION which is defined in the yajl_common.h header file +along with a brief description of the API changes.
+ +A new optional parameter can be given when specifying a calc JSON link. The +time parameter is a string containing a single letter A..L +that selects one of the input links to be used for the timestamp of calculation +if requested. The timestamp will be fetched atomically with the value from the +chosen input link (providing that input link type supports the readLocked() +method).
+ +A soft channel output record with the OUT link unset uses the CONSTANT link +type. The new link type code was causing some soft channel device supports to +return an error status from the write method of that link type, which would +cause a ca_put() operation to such a record to generate an exception. This has +been silenced by giving the constant link types a dummy putValue method. A new +test program has been added to prevent regressions of this behaviour.
+ +In the 3.16.1 release a crash can occur in the IOC's RSRV server when a large +array is made even larger; the previous array buffer was not being released +correctly. See Launchpad +bug +#1706703.
