We are excited to announce 0.22.10 of Dolt. We include the usual slate of bug fixes and performance improvements, as well as:

DOLT_RESET exposed in SQL, part of our roadmap of exposing all Dolt's version control features in SQL
ON DUPLICATE KEY for defining behavior when a duplicate primary key is encountered

As usual, we are grateful for contributions and bug reports.

1190: go/cmd/dolt: Add debugging flag to run with Jaeger span reporting to localhost.
This adds a --jaeger flag to dolt CLI which installs a Jaeger Tracer as the
global opentracing Tracer. The Tracer is configured to report to an HTTP
collector running on http://localhost:14268, which is the port that docker
image jaegertracing/all-in-one listens on.
Also adds some parameters in places where Dolt constructs sql.Contexts to pass
the correct Tracer through.
Also adds a few new Span points, in things like nbs.Get and
metaSequenceImpl.getChildSequence.
