changelog_1021_li=The h2console.war can now be built using the Java build.
changelog_1022_li=By default, databases are shared in the same process. For read-only databases this causes unnecessary synchronization, but safes memory. If you want that each connection opens its own database, append ;OPEN_NEW\=TRUE to the database URL.
changelog_1023_li=New auto-reconnect feature will cause the JDBC driver to reconnect to the database if the connection is lost. To enable, append ;AUTO_RECONNECT\=TRUE to the database URL. This is specially helpful when using AUTO_SERVER. AUTO_SERVER automatically uses auto-reconnect.

changelog_1029_li=Multiple processes can now access the same database without having to explicitly start the server. To do that, append ;AUTO_SERVER\=TRUE to the database URL. In this case, the server is started automatically if the connection is in embedded mode, and the server mode is used if a server is running. If the process that opened the first connection is closed, the other client need to reconnect (there is no automatic re-connect so far). Remote connections are allowed, but only to this database.
changelog_1030_li=The server tool now displays the correct IP address if networked.
changelog_1031_li=Can now start a TCP server with port 0 (automatically select a port).
changelog_1032_li=Result sets with just a unique index can now be updated (previously a primary key was required).

changelog_1047_li=Multi-Version Concurrency (MVCC) may no longer be used when using the multi-threaded kernel feature (MULTI_THREADED). An exception is thrown when trying to connect with both settings. Additional synchronization is required before those features can be used together.
changelog_1048_li=The data type JAVA_OBJECT could not be used in updatable result sets.
changelog_1049_li=The system property h2.optimizeInJoin did not work correctly.
changelog_1050_li=Conditions such as ID\=? AND ID>? were slow.

changelog_1153_li=The plan is to dual-license H2. The additional license is EPL (Eclipse Public License). The current license (MPL, Mozilla Public License) will stay. Current users are not affected because they can keep MPL. EPL is very similar to MPL, the only bigger difference is related to patents (EPL is a bit more business friendly in this regard). See also http\://opensource.org/licenses/eclipse-1.0.php, http\://www.eclipse.org/legal/eplfaq.php (FAQ), http\://blogs.zdnet.com/Burnette/?p\=131

Future plan\:support creating custom h2 distributions (for embedded use). Maybe create a new project 'Jant' or 'Javen' if other people are interested.
changelog_1163_li=The jar file is now about 10% smaller because the variable debugging info is no longer included. The source file and line number debugging info is still included. If required, the jar file size of the full version can be further reduced to about 720 KB using 'build jarSmall' or even more by removing unneeded components.
changelog_1164_li=Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome\!

changelog_1185_li=Fulltext search (native implementation)\:The words table is no longer an in-memory table because this caused memory problems in some cases.
changelog_1186_li=It was possible to create a role with the name as an existing user (but not vice versa). This is not allowed any more.
changelog_1187_li=The recovery tool didn't work correctly for tables without rows.
changelog_1188_li=For years below 1, the YEAR method didn't return the correct value, and the conversion from date and timestamp to varchar was incorrect.
changelog_1189_li=CSVWRITE caused a NullPointerException when not specifying a nullString.
changelog_1190_li=When a log file switch occurred just after a truncate table or drop table statement, the database could not be started normally (RECOVER\=1 was required). Fixed.

changelog_1197_li=ALTER SEQUENCE and ALTER TABLE ALTER COLUMN RESTART can now be used inside a transaction.
changelog_1198_li=New system property h2.aliasColumnName. When enabled, aliased columns (as in SELECT ID AS I FROM TEST) return the real table and column name in ResultSetMetaData.getTableName() and getColumnName(). This is disabled by default for compatibility with other databases (HSQLDB, Apache Derby, PostgreSQL, some version of MySQL). In version 1.1 this setting will be enabled.
changelog_1199_li=When using encrypted databases, and using the wrong file password, the log file was renamed if the database was not already open. Fixed.

changelog_1204_li=When using multi-version concurrency (MVCC\=TRUE), duplicate rows could appear in the result set when running queries with uncommitted changes in the same session.
changelog_1205_li=H2 Console\:remote connections were very slow because getHostName/getRemoteHost was used. Fixed (now using getHostAddress/getRemoteAddr.
changelog_1206_li=H2 Console\:on Linux, Firefox, Konqueror, or Opera (in this order) are now started if available. This has been tested on Ubuntu.
changelog_1207_li=H2 Console\:the start window works better with IKVM
changelog_1208_li=H2 Console\:improved compatibility with Safari (Safari requires keep-alive)

changelog_1154_li=The plan is to dual-license H2. The additional license is EPL (Eclipse Public License). The current license (MPL, Mozilla Public License) will stay. Current users are not affected because they can keep MPL. EPL is very similar to MPL, the only bigger difference is related to patents (EPL is a bit more business friendly in this regard). See also http\://opensource.org/licenses/eclipse-1.0.php, http\://www.eclipse.org/legal/eplfaq.php (FAQ), http\://blogs.zdnet.com/Burnette/?p\=131

Future plan\:support creating custom h2 distributions (for embedded use). Maybe create a new project 'Jant' or 'Javen' if other people are interested.
changelog_1164_li=The jar file is now about 10% smaller because the variable debugging info is no longer included. The source file and line number debugging info is still included. If required, the jar file size of the full version can be further reduced to about 720 KB using 'build jarSmall' or even more by removing unneeded components.
changelog_1165_li=Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome\!

changelog_1189_li=For years below 1, the YEAR method didn't return the correct value, and the conversion from date and timestamp to varchar was incorrect.
changelog_1190_li=CSVWRITE caused a NullPointerException when not specifying a nullString.
changelog_1191_li=When a log file switch occurred just after a truncate table or drop table statement, the database could not be started normally (RECOVER\=1 was required). Fixed.

changelog_1225_li=The H2 Console has been translated to Dutch. Thanks a lot to Remco Schoen\!
changelog_1226_li=Databases can now be opened even if trigger classes are not in the classpath. The exception is thrown when trying to fire the trigger.
changelog_1227_li=Opening databases with ACCESS_MODE_DATA\=r is now supported. In this case the database is read-only, but the files don't not need to be read-only.
changelog_1228_li=Security\:The database now waits 200 ms before throwing an exception if the user name or password don't match, to slow down dictionary attacks.
changelog_1229_li=The value cache is now a soft reference cache. This should help save memory.
