There were significant changes made to DataStore
API between 11.3 and 12.0, so definitely be prepared for surprises. After 12.0 I can't recall any major changes except for bugfixes.
I haven't compared DataStore
with WXF in terms of speed, but I can confirm that at least for passing a list of Strings to/from Library DataStore
is significantly faster than WSTP. If you decide to benchmark DataStore
against WXF please share your results.
