@MathiasVDA
Correction for GEoSPARQL #3577
@AtesComp
Update Fuseki Edit view CodeMirror usage
== Impact:
The minimum version of Java is now Java21.
= TDB2
There is a fix for handling xsd:decimals.
It is advisable to reload data if xsd:decimals have been used.
= geosparql
jena-geosparql: Jena 6 requires re-creation of spatial index files that
were generated with earlier versions. The reason is a bump to the latest
major version of the kryo serialization framework dependency.
In general, it is recommended to back up existing databases including
the spatial indexes prior to engaging in the migration process.
The GeoSPARQL Assembler will automatically re-create all referenced
absent spatial index files. Hence, moving or deleting existing spatial
indexes is usually sufficient. The Fuseki SPARQL server runs spatial
index creation of GeoSPARQL assemblers during server start. This process
may take a while depending on the sizes of the involved datasets.
== Lucene 10
== modules removed:
jena-iri, jena-fuseki-webapp, jena-fuseki-war, jena-permissions
== Package org.apache.jena.tdb removed.
Migrate to TDB2 or use package org.apache.jena.tdb1 (for now).
