@changelog_1036_li
@changelog_1041_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.

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.

Version 1.0.70 (2008-04-20)
@changelog_1166_li
@changelog_1171_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).

@changelog_1172_li
Multi version concurrency (MVCC): when a row was updated, and the updated column was not indexed, this update was visible sometimes for other sessions even if it was not committed.
@changelog_1168_li
@changelog_1173_li
Calling SHUTDOWN on one connection and starting a query on another connection concurrently could result in a Java level deadlock.

@changelog_1180_li
Started to write a Ant replacement ('JAnt') that uses pure Java build definitions. Advantages: ability to debug the build, extensible, flexible, no XML, a bit faster. Future plan: support creating custom h2 distributions (for embedded use). Maybe create a new project 'Jant' or 'Javen' if other people are interested.
@changelog_1176_li
@changelog_1181_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_1177_li
@changelog_1182_li
Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome!

@changelog_1193_li
@changelog_1198_li
New system property h2.sortNullsHigh to invert the default sorting behavior for NULL. The default didn't change.
@changelog_1194_li

@changelog_1200_li
ALTER TABLE or CREATE TABLE now support parameters for the password field.
@changelog_1196_li
@changelog_1201_li
The linear hash has been removed. It was always slower than the b-tree index, and there were some bugs that would be hard to fix.
@changelog_1197_li
@changelog_1202_li
TRACE_LEVEL_ settings are no longer persistent. This was a problem when database initialization code caused a lot of trace output.
@changelog_1198_li
@changelog_1203_li
Fulltext search (native implementation): The words table is no longer an in-memory table because this caused memory problems in some cases.
@changelog_1199_li
@changelog_1204_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_1203_li
@changelog_1208_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_1204_li
@changelog_1209_li
When a log file switch occurred in the middle of a sequence flush (sequences are only flushed every 32 values by default), the sequence value was lost. Fixed.
@changelog_1205_li
@changelog_1210_li
Altering a sequence didn't unlock the system table when autocommit switched off.
@changelog_1206_h2

@changelog_1215_li
ALTER SEQUENCE and ALTER TABLE ALTER COLUMN RESTART can now be used inside a transaction.
@changelog_1211_li
@changelog_1216_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_1212_li
@changelog_1217_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_1270_li
For compatibility with other databases the column default (COLUMN_DEF) for columns without default is now null (it was an empty string).

changelog_1002_li=Linked tables\:the automatic connection sharing didn't work. Actually the system property h2.shareLinkedConnections was working in the opposite direction\:it was disabled when set to true. Now it works as expected.
changelog_1003_li=Opening large database is now faster.
changelog_1004_li=New system property h2.socketConnectTimeout, the timeout in milliseconds to connect to a server. The default is 2000 (2 seconds).
changelog_1005_li=The wrong parameters were bound to subqueries with parameters, specially when using IN(SELECT ...) and IN(...).
changelog_1006_li=Unset parameters were not detected when the query was re-compiled.
changelog_1007_li=New functions ISO_YEAR, ISO_WEEK, ISO_DAY_OF_WEEK. Thanks a lot to Robert Rathsack for implementing those\!
changelog_1008_li=The date functions DAYOFYEAR, DAYOFMONTH, DAYOFWEEK are now called DAY_OF_YEAR, DAY_OF_MONTH, DAY_OF_WEEK (the old names still work).
changelog_1009_li=An out of memory error while deleting or updating many rows could result in a strange exception.
changelog_1010_li=Linked tables\:compatibility with MS SQL Server has been improved.
changelog_1011_li=Renaming tables that have foreign keys with cascade didn't work correctly.

changelog_1014_li=The optimization to group using an index didn't work in some cases in version 1.1 (see also system property h2.optimizeGroupSorted).
changelog_1015_li=OSGi meta data is included in the manifest file. An OSGi BundleActivator is included\:it loads the database driver when starting the bundle, and unloads it when stopping the bundle.
changelog_1016_li=The default value for MAX_MEMORY_UNDO to 50000.
changelog_1017_li=For alias columns, ResultSetMetaData.getTableName() and getColumnName() now return the real table and column name in the default mode.
changelog_1018_li=In SQL scripts created with SCRIPT TO, schemas are now only created if they don't exist yet.
changelog_1019_li=After re-connecting to a database, the database event listener (if set) is informed about it.
changelog_1020_li=Local temporary tables now support indexes. Thanks a lot to Matt Roy\!
changelog_1021_li=RUNSCRIPT no longer uses a temporary file.
changelog_1022_li=New system table INFORMATION_SCHEMA.SESSION_STATE containing the SQL statements that make up the session state. The list currently contains variables (SET @..) and local temporary tables (without data).
changelog_1023_li=After an automatic re-connect, part of the session state stays (the part that is stored in the SESSION_STATE table).
changelog_1024_li=The build didn't work if the directory temp didn't exist before.

changelog_1032_li=Large objects did not work for in-memory databases in server mode in Linux.
changelog_1033_li=Connections from a local address other than 'localhost' were not allowed if remote connections were disabled. This was always a problem, but only got visible in the last release because the server no longer connects to 'localhost' if networked.
changelog_1034_li=The h2console.war can now be built using the Java build.
changelog_1035_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_1036_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_1042_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_1043_li=The server tool now displays the correct IP address if networked.
changelog_1044_li=Can now start a TCP server with port 0 (automatically select a port).
changelog_1045_li=Result sets with just a unique index can now be updated (previously a primary key was required).

changelog_1060_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_1061_li=The data type JAVA_OBJECT could not be used in updatable result sets.
changelog_1062_li=The system property h2.optimizeInJoin did not work correctly.

changelog_1166_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_1176_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_1177_li=Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome\!

changelog_1198_li=Fulltext search (native implementation)\:The words table is no longer an in-memory table because this caused memory problems in some cases.
changelog_1199_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_1200_li=The recovery tool didn't work correctly for tables without rows.
changelog_1201_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_1202_li=CSVWRITE caused a NullPointerException when not specifying a nullString.
changelog_1203_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_1211_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_1212_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_1213_li=Improved performance when using lob files in directories (however this is still disabled by default)

changelog_1217_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_1218_li=H2 Console\:remote connections were very slow because getHostName/getRemoteHost was used. Fixed (now using getHostAddress/getRemoteAddr.
changelog_1219_li=H2 Console\:on Linux, Firefox, Konqueror, or Opera (in this order) are now started if available. This has been tested on Ubuntu.
changelog_1220_li=H2 Console\:the start window works better with IKVM
changelog_1221_li=H2 Console\:improved compatibility with Safari (Safari requires keep-alive)
changelog_1222_li=Random\:the process didn't stop if generating the random seed using the standard way (SecureRandom.generateSeed) was very slow. Now using a daemon thread to avoid this problem.

changelog_1171_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_1181_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_1182_li=Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome\!

changelog_1205_li=The recovery tool didn't work correctly for tables without rows.
changelog_1206_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_1207_li=CSVWRITE caused a NullPointerException when not specifying a nullString.
changelog_1208_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.
