I've published a release from my fork a couple days ago, because Kuree's repo seems abandoned:
s4pe 0.4.1 beta -- this can deal with the longer tags introduced with 1.13; COBJ is updated based on the info from
here and it should now preview all XML types as XML ( = no more UNKN with empty preview panels).
Contains updates by CmarNYC /
@cmarinetti, Buzzler, and myself; via the previous version it also includes older updates by
@IngeJones. The source for the CASP/TONE/RegionMap updates in that version is available separately
here.
