+* The GS1 Application Specification Table profiles were reconciled with Release 26.0 of the GS1 General Specifications: GS1 DataMatrix and GS1 QR Code under gs1.sst4 and gs1.sst9, GS1 DataBar Stacked under gs1.sst4 and gs1.sst10, and GS1 DataMatrix under gs1.sst1 now have the specified X-dimensions and heights, and gs1.sst1.dl for GS1 DataMatrix and the GS1 Digital Link symbols now allows the specified maximum X-dimension of 0.990 mm.
+* Added gs1.sst3 for GS1 DataMatrix and the GS1 Digital Link symbols, and gs1.sst2 for GS1 DataBar Truncated.
+* Removed the gs1.sst2 profile for EAN-8 and the gs1.sst1, gs1.sst1.dl and gs1.sst8 profiles for GS1 QR Code, which the GS1 General Specifications do not define; selecting them now raises bwipp.renderUnknownAST.
+* Each AST profile is now described by an "AST {profile}" metadata property, which libpostscriptbarcode and the bindings read as any other property.
