Beta 6.5

>>> In February, we start beta on 6.5, which will have multi-version
>>> concurrency control, thanks to Vadim. For those of you who did not
like
>>> our table-level locking, you will be really surprised. Not only do
we
>>> have row-level locking, we have something even better. In row-level
>>> locking, a reader can not read a row that is locked by a writer. In
the
>>> 6.5 locking system, READERS ARE NEVER BLOCKED, and writers block
only if
>>> they try to modify a _row_ that another writer has modified and not
>>> committed.
>>>
>>> This is a major feature, better than many commercial databases.
There

>>> transaction ids take care of that. A true NUMERIC type with
>>> user-specified precision is also planned for 6.5, thanks to Jan.

Bruce, this sounds great.
