• XSLT stylesheets now load constraints and constructors using SPARQL over the namespace endpoint
• The URIs of ontology terms are not relative to the app's base URI anymore
• Additional assertions added to external ontology terms instead of subclassing them
• Every UI state generates a distinct URL which is loaded consistently on both server- and client-side
• Upgraded Jena to 4.3.2

• ExceptionMapper constructors with injection in order to align with Processor
• An option to override request URI using the ?uri= URL param, implemented in ApplicationFilter
• Dispatcher as the new "entrypoint" JAX-RS resource which routes between ResourceBase (if app is not empty) and ProxyResourceBase (if app is empty)
• Missing XML namespace definitions to client-side XSLT stylesheets

• Simplified ResourceBase::describe by removing the ?uri= indirection logic

Removed

• Proxy injections from injection factory binders

[2.1.55] - 2021-03-26

• Dydra-specific QuadStoreClient and GraphStoreClient with support for asynchonous GSP requests

Changed

• Ontology classes that used to be in the ns: namespace (${base}ns#) moved to nsds: (${base}ns/domain/system#)
