The users@ message said "a few weeks" and I was all set to do the
release ...
Then the JENA-450 report came in. JENA-450 is the problem that code
can't create OntModels inside read transactions when the model is new --
it tries to set prefixes and read-only really is read-only.
The OntModelImpl constructor copies in prefixes from the profile. If
the model is new, the prefixes aren't defined in the model, and the code
sets them. But it can't.
A couple of possible fixes:
1/ Put try{} around the setNsPrefix loop and skip if an exception occurs.
2/ Always have an updatable in-memory prefix mapping for read-only model.
(2) seems better but I'm not absolutely sure how to achieve it yet
within the current mechanism.
Long term, beyond 2.10.1, changing the design of TDB graphs to have
graphs work across transaction boundaries looks like the right thing to
do. The graph also carries around internal details used by the query
execution engine. Then model.begin/model.commit can work as a write
transaction. Not the sort of thing to do just before a release after
people have tested for us.
For this release, I suggest a short amount of time to see if there is
some temporary fix for JENA-450 (e.g. 1), then do the release
regardless. This isn't a regression; it does need fixing; there are
many other things in 2.10.1 that are better than 2.10.0.

So far, so good.
There have been some useful reports, including SDB, and some
fixes/additions:
+ Added improved Fuseki start script
+ OpAsQuery fix rewriting nested selects
+ Optimizer improvement for DISTINCT and ORDER BY
+ Serializing queries for SERVICE: property paths could break the syntax.
+ One significant fix to RIOT in the handling file: URIs mostly
affecting Windows
+ Query timeouts now work as advertised
JENA-447 is SDB related but it's not a regression as far as I can see.
(Seems to be something with concurrent, transactions and the bulk loader.)
