<h2>Version 1.4.195 (2017-04-23)</h2>
<ul>
<li>Lazy query execution support.
</li>
<li>Added API for handling custom data types (System property "h2.customDataTypesHandler", API org.h2.api.CustomDataTypesHandler).

Introduce a queue when doing table locking to prevent session starvation.
</li></ul>
<h2>Version 1.4.179 Beta (2014-06-23)</h2>
<ul><li>The license was changed to MPL 2.0 (from 1.0) and EPL 1.0.
</li><li>Issue 565: MVStore: concurrently adding LOB objects
(with MULTI_THREADED option) resulted in a NullPointerException.
</li><li>MVStore: reduced dependencies to other H2 classes.
</li><li>There was a way to prevent a database from being re-opened,
by creating a column constraint that references a table with a higher id,
for example with "check" constraints that contains queries.
This is now detected, and creating the table is prohibited.
In future versions of H2, most likely creating references to other
tables will no longer be supported because of such problems.
</li><li>MVStore: descending indexes with "nulls first" did not work as expected
(null was ordered last).
</li><li>Large result sets now always create temporary tables instead of temporary files.
</li><li>When using the PageStore, opening a database failed in some cases with a NullPointerException
if temporary tables were used (explicitly, or implicitly when using large result sets).
</li><li>If a database file in the PageStore file format exists, this file and this mode
is now used, even if the database URL does not contain "MV_STORE=FALSE".
If a MVStore file exists, it is used.
</li><li>Databases created with version 1.3.175 and earlier
that contained foreign keys in combination with multi-column indexes
could not be opened in some cases.
This was due to a bugfix in version 1.3.176:
Referential integrity constraints sometimes used the wrong index.
</li><li>MVStore: the ObjectDataType comparison method was incorrect if one
key was Serializable and the other was of a common class.
</li><li>Recursive queries with many result rows (more than the setting "max_memory_rows")
did not work correctly.
</li><li>The license has changed to MPL 2.0 + EPL 1.0.
</li><li>MVStore: temporary tables from result sets could survive re-opening a database,
which could result in a ClassCastException.
</li><li>Issue 566: MVStore: unique indexes that were created later on did not work correctly
if there were over 5000 rows in the table.
Existing databases need to be re-created (at least the broken index need to be re-built).
</li><li>MVStore: creating secondary indexes on large tables
results in missing rows in the index.
</li><li>Metadata: the password of linked tables is now only visible for admin users.
</li><li>For Windows, database URLs of the form "jdbc:h2:/test" where considered
relative and did not work unless the system property "h2.implicitRelativePath" was used.
</li><li>Windows: using a base directory of "C:/" and similar did not work as expected.
</li><li>Follow JDBC specification on Procedures MetaData, use P0 as
return type of procedure.
</li><li>Issue 531: IDENTITY ignored for added column.
</li><li>FileSystem: improve exception throwing compatibility with JDK
</li><li>Spatial Index: adjust costs so we do not use the spatial index if the
query does not contain an intersects operator.
</li><li>Fix multi-threaded deadlock when using a View that includes a TableFunction.
</li><li>Fix bug in dividing very-small BigDecimal numbers.
</li></ul>
<h2>Version 1.4.178 Beta (2014-05-02)</h2>
<ul><li>Issue 559: Make dependency on org.osgi.service.jdbc optional.
</li><li>Improve error message when the user specifies an unsupported combination of database settings.
</li><li>MVStore: in the multi-threaded mode, NullPointerException and other exceptions could occur.
</li><li>MVStore: some database file could not be compacted due to a bug in
the bookkeeping of the fill rate. Also, database file were compacted quite slowly.
This has been improved; but more changes in this area are expected.
</li><li>MVStore: support for volatile maps (that don't store changes).
</li><li>MVStore mode: in-memory databases now also use the MVStore.
</li><li>In server mode, appending ";autocommit=false" to the database URL was working,
but the return value of Connection.getAutoCommit() was wrong.
</li><li>Issue 561: OSGi: the import package declaration of org.h2 excluded version 1.4.
</li><li>Issue 558: with the MVStore, a NullPointerException could occur when using LOBs
at session commit (LobStorageMap.removeLob).
</li><li>Remove the "h2.MAX_MEMORY_ROWS_DISTINCT" system property to reduce confusion.
We already have the MAX_MEMORY_ROWS setting which does a very similar thing, and is better documented.
</li><li>Issue 554: Web Console in an IFrame was not fully supported.
</li></ul>
<h2>Version 1.4.177 Beta (2014-04-12)</h2>
<ul><li>By default, the MV_STORE option is enabled, so it is using the new MVStore
storage. The MVCC setting is by default set to the same values as the MV_STORE setting,
so it is also enabled by default. For testing, both settings can be disabled by appending
";MV_STORE=FALSE" and/or ";MVCC=FALSE" to the database URL.
</li><li>The file locking method 'serialized' is no longer supported.
This mode might return in a future version,
however this is not clear right now.
A new implementation and new tests would be needed.
</li><li>Enable the new storage format for dates (system property "h2.storeLocalTime").
For the MVStore mode, this is always enabled, but with version 1.4
this is even enabled in the PageStore mode.
</li><li>Implicit relative paths are disabled (system property "h2.implicitRelativePath"),
so that the database URL jdbc:h2:test now needs to be written as jdbc:h2:./test.
</li><li>"select ... fetch first 1 row only" is supported with the regular mode.
This was disabled so far because "fetch" and "offset" are now keywords.
See also Mode.supportOffsetFetch.
</li><li>Byte arrays are now sorted in unsigned mode
(x'99' is larger than x'09').
(System property "h2.sortBinaryUnsigned", Mode.binaryUnsigned, setting "binary_collation").
</li><li>Csv.getInstance will be removed in future versions of 1.4.
Use the public constructor instead.
</li><li>Remove support for the limited old-style outer join syntax using "(+)".
Use "outer join" instead.
System property "h2.oldStyleOuterJoin".
</li><li>Support the data type "DATETIME2" as an alias for "DATETIME", for MS SQL Server compatibility.
</li><li>Add Oracle-compatible TRANSLATE function, patch by Eric Chatellier.
</li></ul>
<h2>Version 1.3.176 (2014-04-05)</h2>
<ul><li>The file locking method 'serialized' is no longer documented,
as it will not be available in version 1.4.
</li><li>The static method Csv.getInstance() was removed.
Use the public constructor instead.
</li><li>The default user name for the Script, RunScript, Shell,
and CreateCluster tools are no longer "sa" but an empty string.
</li><li>The stack trace of the exception "The object is already closed" is no longer logged by default.
</li><li>If a value of a result set was itself a result set, the result
could only be read once.
</li><li>Column constraints are also visible in views (patch from Nicolas Fortin for H2GIS).
</li><li>Granting a additional right to a role that already had a right for that table was not working.
</li><li>Spatial index: a few bugs have been fixed (using spatial constraints in views,
transferring geometry objects over TCP/IP, the returned geometry object is copied when needed).
</li><li>Issue 551: the datatype documentation was incorrect (found by Bernd Eckenfels).
</li><li>Issue 368: ON DUPLICATE KEY UPDATE did not work for multi-row inserts.
Test case from Angus Macdonald.
</li><li>OSGi: the package javax.tools is now imported (as an optional).
</li><li>H2 Console: auto-complete is now disabled by default, but there is a hot-key (Ctrl+Space).
</li><li>H2 Console: auto-complete did not work with multi-line statements.
</li><li>CLOB and BLOB data was not immediately removed after a rollback.
</li><li>There is a new Aggregate API that supports the internal H2 data types
(GEOMETRY for example). Thanks a lot to Nicolas Fortin for the patch!
</li><li>Referential integrity constraints sometimes used the wrong index,
such that updating a row in the referenced table incorrectly failed with
a constraint violation.
</li><li>The Polish translation was completed and corrected by Wojtek Jurczyk. Thanks a lot!
</li><li>Issue 545: Unnecessary duplicate code was removed.
</li><li>The profiler tool can now process files with full thread dumps.
</li><li>MVStore: the file format was changed slightly.
</li><li>MVStore mode: the CLOB and BLOB storage was re-implemented and is
now much faster than with the PageStore (which is still the default storage).
</li><li>MVStore mode: creating indexes is now much faster
(in many cases faster than with the default PageStore).
</li><li>Various bugs in the MVStore storage and have been fixed,
including a bug in the R-tree implementation.
The database could get corrupt if there were transient IO exceptions while storing.
</li><li>The method org.h2.expression.Function.getCost could throw a NullPointException.
</li><li>Storing LOBs in separate files (outside of the main database file)
is no longer supported for new databases.
</li><li>Lucene 2 is no longer supported.
</li><li>Fix bug in calculating default MIN and MAX values for SEQUENCE.
</li><li>Fix bug in performing IN queries with multiple values when IGNORECASE=TRUE
</li><li>Add entry-point to org.h2.tools.Shell so it can be called from inside an application.
patch by Thomas Gillet.
</li><li>Fix bug that prevented the PgServer from being stopped and started multiple times.
</li><li>Support some more DDL syntax for MySQL, patch from Peter Jentsch.
</li><li>Issue 548: TO_CHAR does not format MM and DD correctly when the month or day of
the month is 1 digit, patch from "the.tucc"
</li><li>Fix bug in varargs support in ALIAS's, patch from Nicolas Fortin
