JDK 1.5 is now required to build the jar file. However it is still possible to create a jar file for Java 1.4. For details, see buildRelease.sh and buildRelease.bat. As an alternative, compile using JDK 1.5 or 1.6 and use Retrotranslator to create a Java 1.4 version (http://retrotranslator.sourceforge.net/).

When deleting or updating many rows in a table, the space in the index file was not re-used in the default mode (persistent database, b-tree index, LOG=1). This caused the index file to grow over time. Workarounds were to delete and re-created the index file, alter the table (add a remove a column), or append ;LOG=2 to the database URL. To disable the change, set the system property h2.reuseSpaceBtreeIndex to false.

Cache: support for a second level soft-references cache. To enable it, append ;CACHE_TYPE=SOFT_LRU (or SOFT_TQ) to the database URL, or set the system property h2.cacheTypeDefault to "SOFT_LRU" / "SOFT_TQ". Enabling the second level cache reduces performance for small databases, but speeds up large databases. It makes sense to use it if the available memory size is unknown. Thanks a lot to Jan Kotek!

changelog_1000_h1=Change Log
changelog_1001_h2=Next Version (unreleased)
changelog_1001_h2=Next Version (unreleased)
changelog_1002_li=H2 Console\:large text is now abbreviated as follows\:text... (100000 characters). A large binary is abbreviated as follows\:hex... (100000 bytes).
changelog_1002_li=The user home directory prefix (~) is now only expanded when followed by a slash or backslash, or standing alone.
changelog_1003_li=Faster data conversion from BIGINT or INT to DECIMAL.
changelog_1003_li=Native fulltext search\:before inserting or deleting data, FT_INIT() had to be called. This is no longer required.
changelog_1004_h2=Version 1.2.126 (2009-12-18)
changelog_1004_li=The .trace.db file is now only created if required.
changelog_1005_li=The ChangeFileEncryption tool will now fail with an exception if the database is still in use. The Backup tool will also fail except when running in quiet mode.
changelog_1006_li=CSVREAD\:when reading the column names from the CSV file, column names that contain no special characters are considered case insensitive now.
changelog_1006_li=Trying to open a database in read-only mode when a .lock.db file exists will now fail with a nice error message.
changelog_1007_li=Optimization index conditions of the form 'column\=NULL' (which is always false; unlike 'column IS NULL').
changelog_1007_li=H2 Console\:data that is too long is now abbreviated as follows\:text... (100000 characters). A large binary is abbreviated as follows\:abcdef... (100000 bytes).
changelog_1008_li=Script command and tool\:the primary key constraint is now listed before inserting the data. This will result in a smaller database when using the page store.
changelog_1008_li=Faster data conversion from BIGINT or INT to DECIMAL.
changelog_1009_li=Statements with IN(SELECT..) conditions could produce the wrong result. Example\:index on id, name; query\:select * from test where id between 1 and 3 and name in (select 'World').
changelog_1009_li=Server-less multi-connection mode\:try to delete log files if switching between read/write operations.
changelog_1010_li=Statements with IN(..) conditions could produce the wrong result when using views or nested select statements. Example\:index on id; index on name; query\:select * from (select * from test) where id\=1 and name in('a', 'b'). select * from (select * from test) where id\=1 and name in('Hello', 'World').
changelog_1010_h2=Version 1.2.126 (2009-12-18)
changelog_1011_li=Page store\:a rollback of a relatively large transaction could fail with an ArrayIndexOutOfBoundsException or a 'row not found' exception in the PageBtreeIndex in some cases.
changelog_1011_li=The ChangeFileEncryption tool will now fail with an exception if the database is still in use. The Backup tool will also fail except when running in quiet mode.
changelog_1012_li=JaQu\:the decompiler has been improved, and a few test cases already work. It is still incomplete however.
changelog_1012_li=CSVREAD\:when reading the column names from the CSV file, column names that contain no special characters are considered case insensitive now.
changelog_1013_li=LIKE\:any letter is now allowed after the escape character (which is still '\\' by default). Previously, an exception was thrown (unlike other databases) if it was not the escape character, '_' or '%'. If the escape character appears at the end of the pattern, the result is it is ignored (like PostgreSQL and MS SQL Server).
changelog_1013_li=Optimization index conditions of the form 'column\=NULL' (which is always false; unlike 'column IS NULL').
changelog_1014_li=The reserve heap memory is no longer used.
changelog_1014_li=Script command and tool\:the primary key constraint is now listed before inserting the data. This will result in a smaller database when using the page store.
changelog_1015_li=Database.checkpoint() could throw a NullPointerException.
changelog_1015_li=Statements with IN(SELECT..) conditions could produce the wrong result. Example\:index on id, name; query\:select * from test where id between 1 and 3 and name in (select 'World').
changelog_1016_h2=Version 1.2.125 (2009-12-06)

Example\:index on id; index on name; query\:select * from (select * from test) where id\=1 and name in('a', 'b'). select * from (select * from test) where id\=1 and name in('Hello', 'World').
changelog_1017_li=Lucene fulltext search\:the Lucene field names now match the table column names, except if the column names start with _ (in which case another _ is prepended). Unfortunately this change means existing fulltext indexes need to be re-built.
changelog_1017_li=Page store\:a rollback of a relatively large transaction could fail with an ArrayIndexOutOfBoundsException or a 'row not found' exception in the PageBtreeIndex in some cases.
changelog_1018_li=The shell tool now has a very simple statement history.
changelog_1018_li=JaQu\:the decompiler has been improved, and a few test cases already work. It is still incomplete however.
changelog_1019_li=The zip file system implementation now supports the '~' home directory prefix. Example database URL\:jdbc\:h2\:zip\:~/test.zip\!/test
changelog_1019_li=LIKE\:any letter is now allowed after the escape character (which is still '\\' by default). Previously, an exception was thrown (unlike other databases) if it was not the escape character, '_' or '%'. If the escape character appears at the end of the pattern, the result is it is ignored (like PostgreSQL and MS SQL Server).
changelog_1020_li=Right outer joins on tables that were already 'inner joined' was processed incorrectly.
changelog_1020_li=The reserve heap memory is no longer used.

changelog_1023_li=When the system property h2.maxMemoryRowsDistinct was set, and using SELECT DISTINCT, the temporary table was not correctly dropped. This could cause problems in recovery when the process was killed.
changelog_1023_li=Lucene fulltext search\:the Lucene field names now match the table column names, except if the column names start with _ (in which case another _ is prepended). Unfortunately this change means existing fulltext indexes need to be re-built.
changelog_1024_li=Trigger that are called before a select statement are now supported. This allows to create tables that work like materialized views.
changelog_1024_li=The shell tool now has a very simple statement history.
changelog_1025_li=Non-row based triggers were called even if the action didn't match the declared action (INSERT triggers were also called when deleting rows). This has been changed. The MERGE statement calls both INSERT and DELETE triggers.
changelog_1025_li=The zip file system implementation now supports the '~' home directory prefix. Example database URL\:jdbc\:h2\:zip\:~/test.zip\!/test
changelog_1026_li=Statements with IN(..) conditions could produce the wrong result or a data conversion error (since version 1.2.120).

changelog_1026_li=Right outer joins on tables that were already 'inner joined' was processed incorrectly.
changelog_1027_li=The CompressTool was not multithreading safe. Because of this, the following database operations where also not multithreading safe (even when using different databases)\:the SCRIPT command (only when using compression), the COMPRESS function, and storing CLOB or BLOB data (only when compression is enabled).
changelog_1027_li=Temporary files from LOB objects were not deleted early enough when using the server mode.
changelog_1028_li=The compression algorithm "LZF" is now about 33% faster than before when compressing small block (around 2 KB). It is much faster than Deflate, but the compression ratio is lower. Some of the optimizations are from Sam Van Oort, thanks a lot\!
changelog_1028_li=Trying to alter a temporary table threw a strange exception. It is still not possible to do that, but the exception message is better now.
changelog_1029_li=Compressing large blocks of data didn't work when using the "Deflate" compression algorithm. Compressing a lot of data could run out of heap memory.
changelog_1029_li=When the system property h2.maxMemoryRowsDistinct was set, and using SELECT DISTINCT, the temporary table was not correctly dropped. This could cause problems in recovery when the process was killed.

changelog_1032_li=Statements with IN(..) conditions could produce the wrong result or a data conversion error (since version 1.2.120). Examples\:index on id, name, condition\:id\=1 and name in('Hello', 'x'); index on id, query\:select * from (select * from test) where id\=1 and name in('Hello', 'World').

changelog_1190_li=Views\:in some situations, an ArrayIndexOutOfBoundsException was thrown when using the same view concurrently.
changelog_1190_li=Triggers\:if there was an exception when initializing a trigger, this exception could be hidden, and in some cases (specially when using the Lucene fulltext index mechanism) a NullPointerException was thrown later on. Now the exception that occurred on init is thrown when changing data.
changelog_1191_li=java.util.UUID is now supported in PreparedStatement.setObject and user defined Java functions. ResultSet.getObject() returns a java.util.UUID when using the UUID data type.
changelog_1191_li=The soft-references cache (CACHE_TYPE\=SOFT_LRU) could throw a NullPointerException.
changelog_1192_li=H2 Console\:the language was reset to the browser language when disconnecting.
changelog_1192_li=To enable the new page store mechanism, append ;PAGE_STORE\=TRUE to the database URL. or set the system property h2.pageStore to true. This mechanism is still experimental, and the file format will change, but it is quite stable now.
changelog_1194_li=Server-less multi-connection mode\:more bugs are fixed.
changelog_1194_li=The new storage mechanism is now alpha quality. To try it out, set the system property "h2.pageStore" to "true" (java -Dh2.pageStore\=true). There are still bugs to be found and fixed, for example inserting many rows references a lot of main memory. Performance is currently about the same as with the regular storage mechanism, but the database file size is smaller. The file format is not stable yet.
changelog_1195_li=The download page now included the SHA1 checksums.
changelog_1195_li=ALTER TABLE could throw an exception "object already exists" in some cases.

changelog_1198_li=H2 Console\:the language was reset to the browser language when disconnecting.
changelog_1199_li=Lucene fulltext search\:FTL_DROP_ALL did not drop the triggers.
changelog_1200_li=Backup\:if the database contained CLOB or BLOB data, the backup included a file entry for the LOB directory. This caused the restore to fail.
changelog_1200_li=Server-less multi-connection mode\:more bugs are fixed.
changelog_1201_li=Data types\:LONG is now an alias for BIGINT.

changelog_1205_li=In some situations, an ArrayIndexOutOfBoundsException was thrown when adding rows. This was caused by a bug in the b-tree code.
changelog_1205_li=Lucene fulltext search\:FTL_DROP_ALL did not drop the triggers.
changelog_1206_li=Microsoft Windows Vista\:when using the the installer, Vista wrote "This program may not have installed correctly." This message should no longer appear (in the h2.nsi file, the line 'RequestExecutionLevel highest' was added).
changelog_1206_li=Backup\:if the database contained CLOB or BLOB data, the backup included a file entry for the LOB directory. This caused the restore to fail.
changelog_1207_li=The Recover tool did not always work when the database contains referential integrity constraints.
changelog_1207_li=Data types\:LONG is now an alias for BIGINT.

changelog_1210_li=Fulltext search\:data is no longer deleted and re-inserted if the indexed columns didn't change.
changelog_1211_li=JDK 1.5 is now required to build the jar file. However it is still possible to create a jar file for Java 1.4. For details, see buildRelease.sh and buildRelease.bat. As an alternative, compile using JDK 1.5 or 1.6 and use Retrotranslator to create a Java 1.4 version (http\://retrotranslator.sourceforge.net/).
changelog_1211_li=In some situations, an ArrayIndexOutOfBoundsException was thrown when adding rows. This was caused by a bug in the b-tree code.
changelog_1212_li=When deleting or updating many rows in a table, the space in the index file was not re-used in the default mode (persistent database, b-tree index, LOG\=1). This caused the index file to grow over time. Workarounds were to delete and re-created the index file, alter the table (add a remove a column), or append ;LOG\=2 to the database URL. To disable the change, set the system property h2.reuseSpaceBtreeIndex to false.
changelog_1212_li=Microsoft Windows Vista\:when using the the installer, Vista wrote "This program may not have installed correctly." This message should no longer appear (in the h2.nsi file, the line 'RequestExecutionLevel highest' was added).

changelog_1216_li=Shell tool\:the built-in commands EXIT, HELP, ?, LIST, and so on didn't work with a semicolon at the end.
changelog_1217_li=Benchmark\:the number of executed statements was incorrect. The H2 database was loaded at the beginning of the test to collect results, now it is loaded at the very end. Thanks to Fred Toussi from HSQLDB for reporting those problems. However the changed do not affect the relative performance.
changelog_1217_li=JDK 1.5 is now required to build the jar file. However it is still possible to create a jar file for Java 1.4. For details, see buildRelease.sh and buildRelease.bat.

To disable the change, set the system property h2.reuseSpaceBtreeIndex to false.
changelog_1219_li=Cache\:support for a second level soft-references cache. To enable it, append ;CACHE_TYPE\=SOFT_LRU (or SOFT_TQ) to the database URL, or set the system property h2.cacheTypeDefault to "SOFT_LRU" / "SOFT_TQ". Enabling the second level cache reduces performance for small databases, but speeds up large databases. It makes sense to use it if the available memory size is unknown. Thanks a lot to Jan Kotek\!

changelog_1224_li=After truncating tables, opening large databases could become slow because indexes were always re-built unnecessarily when opening.
changelog_1224_li=H2 Console\:command line settings are no longer stored in the properties file. They are now only used for the current process, except if they are explicitly saved.
changelog_1225_li=More bugs in the server-less multi-connection mode have been fixed\:Sometimes parameters of prepared statements were lost when a reconnecting. Concurrent read operations were slow. To improve performance, executeQuery(..) must be used for queries (execute(..) switches to the write mode, which is slow).
changelog_1225_li=Cache\:support for a second level soft-references cache. To enable it, append ;CACHE_TYPE\=SOFT_LRU (or SOFT_TQ) to the database URL, or set the system property h2.cacheTypeDefault to "SOFT_LRU" / "SOFT_TQ". Enabling the second level cache reduces performance for small databases, but speeds up large databases. It makes sense to use it if the available memory size is unknown. Thanks a lot to Jan Kotek\!

changelog_1275_h2=Version 1.1.108 (2009-02-28)
changelog_1275_li=New experimental NIO storage mechanism with both FileChannel and memory mapped files. To use it, use the file name prefix nio\:or nioMapped\:as in jdbc\:h2\:nio\:~/test. So far it looks like NIO storage is faster on Mac OS but slower on some Windows systems. Thanks a lot to Jan Kotek for the patch\!

changelog_1285_li=The internal IntArray class did not work correctly when initialized with a zero length array.
changelog_1286_li=New experimental mode to support multiple read-write connections without starting a server. To enable this mode, append ;FILE_LOCK\=SERIALIZED;OPEN_NEW\=TRUE to the database URL. Don't expect high performance when multiple concurrent writers.
changelog_1286_li=The H2 Console web application (war file) did only support ASCII characters. Now UTF-8 is supported.
changelog_1287_li=In a web application, the database classes are not unloaded if a connection is open. This may cause out of memory when re-deploying a web application. The DbStarter is changed to close all connections to the configured database (by executing SHUTDOWN).

changelog_1294_li=The WebServlet did not close the database when un-deploying the web application.
changelog_1295_li=When restarting a web application in Tomcat, an exception was thrown sometimes. In most cases this was a NullPointerException. A workaround in H2 has been implemented. The root cause of the problem is now documented in the FAQ\:Tomcat sets all static fields (final or non-final) to null when unloading a web application. A workaround is to put the h2.jar in the lib directory, or set the system property org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES to false.
changelog_1295_li=The exception message of failed INSERT or MERGE statements now includes all values and the row number.

changelog_1301_li=When restarting a web application in Tomcat, an exception was thrown sometimes. In most cases this was a NullPointerException. A workaround in H2 has been implemented. The root cause of the problem is now documented in the FAQ\:Tomcat sets all static fields (final or non-final) to null when unloading a web application. A workaround is to put the h2.jar in the lib directory, or set the system property org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES to false.
