<h2>Version 1.3.166 (2012-04-08)</h2>
<ul><li>Indexes on column that are larger than half the page size (wide indexes)
could sometimes get corrupt, resulting in an ArrayIndexOutOfBoundsException in PageBtree.getRow
or "Row not found" in PageBtreeLeaf. Also, such indexes used too much disk space.
</li><li>Server mode: when retrieving more than 64 rows each containing a CLOB or BLOB,
the error message "The object is already closed" was thrown.
</li><li>ConvertTraceFile: the time in the trace file is now parsed as a long.
</li><li>Invalid connection settings are now detected.
</li><li>Issue 387: WHERE condition getting pushed into sub-query with LIMIT.
</li></ul>
<h2>Version 1.3.165 (2012-03-18)</h2>
<ul><li>Better string representation for decimal values (for example 0.00000000 instead of 0E-26).
</li><li>Prepared statements could only be re-used if the same data types were used
the second time they were executed.
</li><li>In error messages about referential constraint violation, the values are now included.
</li><li>SCRIPT and RUNSCRIPT: the password can now be set using a prepared statement.
Previously, it was required to be a literal in the SQL statement.
</li><li>MySQL compatibility: SUBSTR with a negative start index now works like MySQL.
</li><li>When enabling autocommit, the transaction is now committed (as required by the JDBC API).
</li><li>The shell script <code>h2.sh</code> did not work with spaces in the path.
It also works now with quoted spaces in the argument list.
Thanks a lot to Shimizu Fumiyuki for the patch!
</li><li>If the transaction log could not be truncated because of an uncommitted transaction,
now "Transaction log could not be truncated" is written to the .trace.db file.
Before, the database file was growing and it was hard to find out what the root cause was.
To avoid the database file from growing, a new feature to automatically rollback the oldest
transaction is available now. To enable it, append ;LOG_SIZE_LIMIT=32 to the database URL
(in that case, the oldest session is rolled back if the transaction log is 32 MB).
</li><li>ALTER TABLE ADD can now add more than one column at a time.
</li><li>Issue 380: ALTER TABLE ADD FOREIGN KEY with an explicit index didn't verify
the index can be used, which would lead to a NullPointerException later on.
</li><li>Issue 384: the wrong kind of exception (NullPointerException) was thrown in a UNION query
with an incorrect ORDER BY expression.
</li><li>Issue 362: support LIMIT in UPDATE statements.
</li><li>Browser: if no default browser is set, Google Chrome is now used if available.
If not available, then Konqueror, Netscape, or Opera is used if available (as before).
</li><li>CSV tool: new feature to disable writing the column header
(option writeColumnHeader).
</li><li>CSV tool: new feature to preserve the case sensitivity of column names
(option caseSensitiveColumnNames).
</li><li>PostgreSQL compatibility: LOG(x) is base 10 in the PostgreSQL mode.

@changelog_1200_li @changelog_1200_li
#Indexes on column that are larger than half the page size (wide indexes) could sometimes get corrupt, resulting in an ArrayIndexOutOfBoundsException in PageBtree.getRow or "Row not found" in PageBtreeLeaf. Also, such indexes used too much disk space. #The SCRIPT statements now supports filtering by schema and table. Thanks a lot to Jacob Qvortrup for providing the patch!
@changelog_1201_li
#Server mode: when retrieving more than 64 rows each containing a CLOB or BLOB, the error message "The object is already closed" was thrown.
@changelog_1202_li
#ConvertTraceFile: the time in the trace file is now parsed as a long.
@changelog_1203_li
#Invalid connection settings are now detected.
@changelog_1204_li
#Issue 387: WHERE condition getting pushed into sub-query with LIMIT.
@changelog_1205_h2
#Version 1.3.165 (2012-03-18)
@changelog_1206_li
#Better string representation for decimal values (for example 0.00000000 instead of 0E-26).
@changelog_1207_li
#Prepared statements could only be re-used if the same data types were used the second time they were executed.
@changelog_1208_li
#In error messages about referential constraint violation, the values are now included.
@changelog_1209_li
#SCRIPT and RUNSCRIPT: the password can now be set using a prepared statement. Previously, it was required to be a literal in the SQL statement.
@changelog_1210_li
#MySQL compatibility: SUBSTR with a negative start index now works like MySQL.
@changelog_1211_li
#When enabling autocommit, the transaction is now committed (as required by the JDBC API).
@changelog_1212_li
#The shell script <code>h2.sh</code> did not work with spaces in the path. It also works now with quoted spaces in the argument list. Thanks a lot to Shimizu Fumiyuki for the patch!
@changelog_1213_li
#If the transaction log could not be truncated because of an uncommitted transaction, now "Transaction log could not be truncated" is written to the .trace.db file. Before, the database file was growing and it was hard to find out what the root cause was. To avoid the database file from growing, a new feature to automatically rollback the oldest transaction is available now. To enable it, append ;LOG_SIZE_LIMIT=32 to the database URL (in that case, the oldest session is rolled back if the transaction log is 32 MB).
@changelog_1214_li
#ALTER TABLE ADD can now add more than one column at a time.
@changelog_1215_li
#Issue 380: ALTER TABLE ADD FOREIGN KEY with an explicit index didn't verify the index can be used, which would lead to a NullPointerException later on.
@changelog_1216_li
#Issue 384: the wrong kind of exception (NullPointerException) was thrown in a UNION query with an incorrect ORDER BY expression.
@changelog_1217_li
#Issue 362: support LIMIT in UPDATE statements.
@changelog_1218_li
#Browser: if no default browser is set, Google Chrome is now used if available. If not available, then Konqueror, Netscape, or Opera is used if available (as before).
@changelog_1219_li
#CSV tool: new feature to disable writing the column header (option writeColumnHeader).
@changelog_1220_li
#CSV tool: new feature to preserve the case sensitivity of column names (option caseSensitiveColumnNames).
@changelog_1221_li
#PostgreSQL compatibility: LOG(x) is base 10 in the PostgreSQL mode.

changelog_1196_li=Small optimisation for accessing result values by column name. changelog_1196_li=Terrence Huang has translated the error messages to Chinese. Thanks a lot\!
changelog_1197_li=Fix for bug in Statement.getMoreResults(int) changelog_1197_li=TRUNC was added as an alias for TRUNCATE.
changelog_1198_li=The SCRIPT statements now supports filtering by schema and table. Thanks a lot to Jacob Qvortrup for providing the patch\! changelog_1198_li=Small optimisation for accessing result values by column name.
changelog_1199_h2=Version 1.3.166 (2012-04-08) changelog_1199_li=Fix for bug in Statement.getMoreResults(int)
changelog_1200_li=Indexes on column that are larger than half the page size (wide indexes) could sometimes get corrupt, resulting in an ArrayIndexOutOfBoundsException in PageBtree.getRow or "Row not found" in PageBtreeLeaf. Also, such indexes used too much disk space. changelog_1200_li=The SCRIPT statements now supports filtering by schema and table. Thanks a lot to Jacob Qvortrup for providing the patch\!
changelog_1201_li=Server mode\: when retrieving more than 64 rows each containing a CLOB or BLOB, the error message "The object is already closed" was thrown.
changelog_1202_li=ConvertTraceFile\: the time in the trace file is now parsed as a long.
changelog_1203_li=Invalid connection settings are now detected.
changelog_1204_li=Issue 387\: WHERE condition getting pushed into sub-query with LIMIT.
changelog_1205_h2=Version 1.3.165 (2012-03-18)
changelog_1206_li=Better string representation for decimal values (for example 0.00000000 instead of 0E-26).
changelog_1207_li=Prepared statements could only be re-used if the same data types were used the second time they were executed.
changelog_1208_li=In error messages about referential constraint violation, the values are now included.
changelog_1209_li=SCRIPT and RUNSCRIPT\: the password can now be set using a prepared statement. Previously, it was required to be a literal in the SQL statement.

changelog_1211_li=When enabling autocommit, the transaction is now committed (as required by the JDBC API).
changelog_1212_li=The shell script <code>h2.sh</code> did not work with spaces in the path. It also works now with quoted spaces in the argument list. Thanks a lot to Shimizu Fumiyuki for the patch\!
changelog_1213_li=If the transaction log could not be truncated because of an uncommitted transaction, now "Transaction log could not be truncated" is written to the .trace.db file. Before, the database file was growing and it was hard to find out what the root cause was. To avoid the database file from growing, a new feature to automatically rollback the oldest transaction is available now. To enable it, append ;LOG_SIZE_LIMIT\=32 to the database URL (in that case, the oldest session is rolled back if the transaction log is 32 MB).
changelog_1214_li=ALTER TABLE ADD can now add more than one column at a time.
changelog_1215_li=Issue 380\: ALTER TABLE ADD FOREIGN KEY with an explicit index didn't verify the index can be used, which would lead to a NullPointerException later on.
changelog_1216_li=Issue 384\: the wrong kind of exception (NullPointerException) was thrown in a UNION query with an incorrect ORDER BY expression.
changelog_1217_li=Issue 362\: support LIMIT in UPDATE statements.
changelog_1218_li=Browser\: if no default browser is set, Google Chrome is now used if available. If not available, then Konqueror, Netscape, or Opera is used if available (as before).
changelog_1219_li=CSV tool\: new feature to disable writing the column header (option writeColumnHeader).
changelog_1220_li=CSV tool\: new feature to preserve the case sensitivity of column names (option caseSensitiveColumnNames).
changelog_1221_li=PostgreSQL compatibility\: LOG(x) is base 10 in the PostgreSQL mode.
