<p>The names of two isolation-level flags changed in the Berkeley DB 4.4 release.
The DB_DEGREE_2 flag was renamed to <a href="../api_reference/C/dbcget.html#dbcget_DB_READ_COMMITTED" class="olink">DB_READ_COMMITTED</a>, and the
DB_DIRTY_READ flag was renamed to <a href="../api_reference/C/dbopen.html#dbopen_DB_READ_UNCOMMITTED" class="olink">DB_READ_UNCOMMITTED</a>, to match
ANSI standard names for isolation levels. The historic flag names
continue to work in this release, but may be removed from future
releases.</p>
