1506.2

DYNLIB (Linux) refinement: when loading libraries, it now checks first in the bin directory before trying the system library path.

1506.1.2

Support new LibXL license option.

1506.1.1

Support new 6.3 PIC code format (XXXXXXX-XXXXXX-XXXXXX-XXXXXXX). The new PIC format is needed for certain extensions added in 6.3; it provides no benefits to 6.2 but is hereby supported just as a backwards capability convenience.
