[ANNOUNCE] Tephra 0.2.1 release

[Gary Helmling <gh...@gmail.com>]

Hi all,

I'm happy to announce the 0.2.1 release of Tephra.

Tephra provides globally consistent transactions on top of Apache
HBase by leveraging HBase's native data versioning to provide
multi-versioned concurrency control (MVCC) for transactional reads and
writes. With MVCC capability, each transaction sees its own consistent
"snapshot" of data, providing snapshot isolation of concurrent
transactions.


This release fixes the following issues:

* TransactionProcessor use of FilterList on flush and compaction causes abort
* Support coverage report generation
* TransactionProcessor should use TransactionVisibilityFilter on flush
and compact
* Cleanup class and package names
* Use Configuration instead of HBaseConfiguration when possible
* TransactionVisibilityFilter should support additional filtering on
visible cells
* Assigned transaction IDs should reflect current timestamp
* Remove using of HBase Bytes in non-HBase related classes in tephra-core

Please note that a number of the Tephra packages and classes have been
renamed for clarity.  Any existing code will need to be updated.

Binary and source distributions of the release are available at:
