@changelog_1003_li
SET LOG 2 was not effective if executed after opening the database.
@changelog_1004_li
Queries with more than 10 tables are now faster.
Translating the H2 Console is now simpler.
@changelog_1005_li

Self referencing constraints didn't restrict deleting rows that reference itself if there is another row that references it.
@changelog_1008_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.
ResultSetMetaData.getColumnName now returns the alias name except for columns.
@changelog_1009_li
Temporary files are now deleted when the database is closed, even if they were not garbage collected so far.
@changelog_1010_h2

@changelog_1017_li
Opening large database is now faster.
@changelog_1010_li
@changelog_1018_li
New system property h2.socketConnectTimeout, the timeout in milliseconds to connect to a server. The default is 2000 (2 seconds).
@changelog_1011_li
@changelog_1019_li
The wrong parameters were bound to subqueries with parameters, specially when using IN(SELECT ...) and IN(...).
@changelog_1012_li
@changelog_1020_li
Unset parameters were not detected when the query was re-compiled.
@changelog_1013_li
@changelog_1021_li
New functions ISO_YEAR, ISO_WEEK, ISO_DAY_OF_WEEK. Thanks a lot to Robert Rathsack for implementing those!
@changelog_1014_li

@changelog_1023_li
An out of memory error while deleting or updating many rows could result in a strange exception.
@changelog_1016_li

@changelog_1020_li
@changelog_1028_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_1021_li
@changelog_1029_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_1022_li
@changelog_1030_li
The default value for MAX_MEMORY_UNDO is now 50000.
@changelog_1023_li

@changelog_1026_li
@changelog_1034_li

@changelog_1027_li
@changelog_1035_li
RUNSCRIPT no longer uses a temporary file.
@changelog_1028_li
@changelog_1036_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_1029_li
@changelog_1037_li
After an automatic re-connect, part of the session state stays (the part that is stored in the SESSION_STATE table).
@changelog_1030_li
@changelog_1038_li
The build didn't work if the directory temp didn't exist before.
@changelog_1031_li

Version 1.1.100 (2008-10-04)
@changelog_1035_li
@changelog_1043_li

@changelog_1036_li
@changelog_1044_li
The H2 Console tool now works with the JDBC-ODBC bridge.
@changelog_1037_li
@changelog_1045_li
The H2 Console tool now supports command line options to start things separately.
@changelog_1038_li
@changelog_1046_li
Large objects did not work for in-memory databases in server mode in Linux.
@changelog_1039_li
@changelog_1047_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_1040_li
@changelog_1048_li
The h2console.war can now be built using the Java build.
@changelog_1041_li
@changelog_1049_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_1042_li
@changelog_1050_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_1043_li
@changelog_1051_li
CreateCluster: the property 'serverlist' is now called 'serverList'.
@changelog_1044_li
@changelog_1052_li
The ConvertTraceFile tool could not parse some files because the trace mechanism did not encode prepared statement parameters.
@changelog_1045_li
@changelog_1053_li
Databases names can now be one character long (the minimum size used to be 2 characters).
@changelog_1046_h2
@changelog_1054_h2
Version 1.0.79 (2008-09-26)
@changelog_1047_li
@changelog_1055_li
Linked tables that point to the same database can now share the connection within the same database. Access to the same connection is serialized. To enable this feature, set the system property h2.shareLinkedConnections to true.
@changelog_1048_li
@changelog_1056_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_1049_li
@changelog_1057_li
The server tool now displays the correct IP address if networked.
@changelog_1050_li
@changelog_1058_li

LINKED TABLE: the schema name can now be set. When multiple tables exist in different schema, and the schema name is not set, an exception is thrown.
@changelog_1053_li
@changelog_1061_li
LINKED TABLE: worked around a bug in Oracle with the CHAR data type.
@changelog_1054_li
@changelog_1062_li

@changelog_1058_li
@changelog_1066_li

@changelog_1063_li
@changelog_1071_li
SET SCHEMA did not work for views.
@changelog_1064_li

@changelog_1065_li
@changelog_1073_li
The maximum log file size setting was ignored for large databases.
@changelog_1066_li
@changelog_1074_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_1067_li
@changelog_1075_li
The data type JAVA_OBJECT could not be used in updatable result sets.
@changelog_1068_li
@changelog_1076_li
The system property h2.optimizeInJoin did not work correctly.
@changelog_1069_li
@changelog_1077_li
Conditions such as ID=? AND ID>? were slow.

@changelog_1071_li
@changelog_1079_li
The documentation no longer uses a frameset (except the Javadocs).
@changelog_1072_li
@changelog_1080_li

@changelog_1172_li
@changelog_1180_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_1189_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.

@changelog_1182_li
@changelog_1190_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_1183_li
@changelog_1191_li
Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome!

The application highlights an automated curve fitting and classification algorithm that outperforms commercial packages in the field. Commercial alternatives are typically small desktop software that handle a few dose response curves at a time. A couple of commercial packages that do handle several thousand curves are very expensive tools (&gt;60k USD) that require manual curation of analysis by the user; require a license to Oracle; lack advanced query/retrieval; and the ability to handle chemical structures.

This application handles chemical structures and biological responses of thousands of compounds with the potential to handle million+ compounds. It utilizes an embedded H2 database to enable flexible query/retrieval of all data including advanced chemical substructure and similarity searching. The application highlights an automated curve fitting and classification algorithm that outperforms commercial packages in the field. Commercial alternatives are typically small desktop software that handle a few dose response curves at a time. A couple of commercial packages that do handle several thousand curves are very expensive tools (&gt;60k USD) that require manual curation of analysis by the user; require a license to Oracle; lack advanced query/retrieval; and the ability to handle chemical structures.
