-<ul><li>Views now store the schema for Java functions if "functions in schemas" is enabled
+<ul><li>A new String cache is now created at most once every 5 second, so that out of memory exceptions
+    are not artifically delayed.
+</li><li>After closing a database, the writer thread will stop after 100 ms at the latest (instead of 1 second).
+</li><li>Opening a large database could fail in theory if the process was killed and then
+    not fully compacted (because the unique transaction log key was re-used).
+</li><li>Views now store the schema for Java functions if "functions in schemas" is enabled
     (system property h2.functionsInSchema).
 </li><li>Improved error message if the LOB files are already deleted on the client side.
 </li><li>Closing a Statement or PreparedStatement at the same time as executing a statement

+When executing a query, at most one index per join can be used.
+If the same table is joined multiple times, for each join only one index is used
+(the same index could be used for both joins, or each join could use a different index).
 Example: for the query
 <code>SELECT * FROM TEST T1, TEST T2 WHERE T1.NAME='A' AND T2.ID=T1.ID</code>,
 two index can be used, in this case the index on NAME for T1 and the index on ID for T2.
