In the last month we've had two updates of new transactional storage engines for MySQL. Falcon, the new storage engine developed by DBMS guru Jim Starkey is now in Alpha. And PBXT, from Paul McCullugh at PrimeBase has a new Beta available with referential integrity. Both use the new storage engine facilities of MySQL 5.1 and are important developments giving more choice to developers building transactional applications. I'm sure there will be more information on these and other storage engines at the MySQL Conference in April.
