- Fix NCF-157 to modify DAP code to support partial variable retrieval. - Fix of NCF-154 to solve problem of ncgen improperly processing data lists for variables of size greater than 2**18 bytes. - Fix ncgen processing of char variables that have multiple unlimited dimensions. - Partly fix Jira issue: NCF-145 (vlen issues). - Benchmark program nc_test4/tst_ar4_*) requires arguments and should only be invoked inside a shell script; fixed so that they terminate cleanly if invoked with no arguments. - Fix the Doxygen processing so it will work with make distcheck. - Begin switchover to using an alternative to ncio. - Begin support for in-memory (diskless) files.
