FYI, the SOSLIB has been updated, taking us to revision 164. The preferred way to update is to LOG DSK0:[901,2] and then RUN SOSUPD, which uses the UpdateCenter to download just the files that have changed.

Release notes are at: soslib.html

The main items of interest here are the fixes to ATPXFR.SBX and ATEAPX.SBX (for those who use them), and for XTREE developers, cleaned up or improved versions of XTRA4 (inter-XTREE drag/drop), XTRA5 (tooltips), and XTRA15 (property sheet mode).

I have not created a zip version, but other than that, you may want to read the notes associated with the prior SOSLIB 151 update (in this forum) for general information about the SOSLIB.
