An ArrayIndexOutOfBoundsException was thrown in some cases when opening an old version 1.3 database, or an 1.4 database with both "mv_store=false" and the system property "h2.storeLocalTime" set to false. It mainly showed up with an index on a time, date, or timestamp column.

changelog_1059_li=MVStore\:updates that affected many rows were were slow in some cases if there was a secondary index.
changelog_1060_li=Using "runscript" with autocommit disabled could result in a lock timeout on the internal table "SYS".
changelog_1061_li=The Servlet API 3.0.1 is now used, instead of 2.4.
changelog_1061_li=Issue 603\:there was a memory leak when using H2 in a web application. Apache Tomcat logged an error message\:"The web application ... created a ThreadLocal with key of type [org.h2.util.DateTimeUtils$1]".
changelog_1062_li=MVStore\:old chunks no longer removed in append-only mode.
changelog_1062_li=When using the MVStore, running a SQL script generate by the Recover tool from a PageStore file failed with a strange error message (NullPointerException), now a clear error message is shown.
changelog_1063_li=MVStore\:the cache for page references could grow far too big, resulting in out of memory in some cases.

changelog_1064_li=MVStore\:orphaned lob objects were not correctly removed in some cases, making the database grow unnecessarily.
changelog_1064_li=Queries that use the same table alias multiple times now work. Before, the select expression list was expanded incorrectly. Example\:"select * from a as x, b as x".
changelog_1065_li=MVStore\:the maximum cache size was artificially limited to 2 GB (due to an integer overflow).
changelog_1065_li=The MySQL compatibility feature "insert ... on duplicate key update" did not work with a non-default schema.
changelog_1066_li=MVStore / TransactionStore\:concurrent updates could result in a "Too many open transactions" exception.
changelog_1066_li=Issue 599\:the condition "in(x, y)" could not be used in the select list when using "group by".
changelog_1067_li=StringUtils.toUpperEnglish now has a small cache. This should speed up reading from a ResultSet when using the column name.
changelog_1067_li=The LIRS cache could grow larger than the allocated memory.
changelog_1068_li=MVStore\:up to 65535 open transactions are now supported. Previously, the limit was at most 65535 transactions between the oldest open and the newest open transaction (which was quite a strange limit).
changelog_1068_li=A new file system implementation that re-opens the file if it was closed due to the application calling Thread.interrupt(). File name prefix "retry\:". Please note it is strongly recommended to avoid calling Thread.interrupt; this is a problem for various libraries, including Apache Lucene.
changelog_1069_li=The default limit for in-place LOB objects was changed from 128 to 256 bytes. This is because each read creates a reference to a LOB, and maintaining the references is a big overhead. With the higher limit, less references are needed.
changelog_1069_li=MVStore\: use RandomAccessFile file system if the file name starts with "file\:".
changelog_1070_li=Tables without columns didn't work. (The use case for such tables is testing.)
changelog_1070_li=Allow DATEADD to take a long value for count when manipulating milliseconds.
changelog_1071_li=The LIRS cache now resizes the table automatically in all cases and no longer needs the averageMemory configuration.
changelog_1071_li=When using MV_STORE\=TRUE and the SET CACHE_SIZE setting, the cache size was incorrectly set, so that it was effectively 1024 times smaller than it should be.
changelog_1072_li=Creating a linked table from an MVStore database to a non-MVStore database created a second (non-MVStore) database file.
changelog_1072_li=Concurrent CREATE TABLE... IF NOT EXISTS in the presence of MULTI_THREAD\=TRUE could throw an exception.
changelog_1073_li=In version 1.4.184, a bug was introduced that broke queries that have both joins and wildcards, for example\:select * from dual join(select x from dual) on 1\=1
changelog_1073_li=Fix bug in MVStore when creating lots of temporary tables, where we could run out of transaction IDs.
changelog_1074_li=Issue 598\:parser fails on timestamp "24\:00\:00.1234" - prevent the creation of out-of-range time values.
changelog_1074_li=Add support for PostgreSQL STRING_AGG function. Patch by Fred Aquiles.
changelog_1075_li=Allow declaring triggers as source code (like functions). Patch by Sylvain Cuaz.
changelog_1075_li=Fix bug in "jdbc\:h2\:nioMemFS" isRoot() function. Also, the page size was increased to 64 KB.
changelog_1076_li=Make the planner use indexes for sorting when doing a GROUP BY where all of the GROUP BY columns are not mentioned in the select. Patch by Frederico (zepfred).
changelog_1079_li=MVStore\:the cache for page references could grow far too big, resulting in out of memory in some cases.
changelog_1080_li=In version 1.4.184, "group by" ignored the table name, and could pick a select column by mistake. Example\:select 0 as x from system_range(1, 2) d group by d.x;
changelog_1080_li=MVStore\:orphaned lob objects were not correctly removed in some cases, making the database grow unnecessarily.
changelog_1081_li=New connection setting "REUSE_SPACE" (default\:true). If disabled, all changes are appended to the database file, and existing content is never overwritten. This allows to rollback to a previous state of the database by truncating the database file.
changelog_1081_li=MVStore\:the maximum cache size was artificially limited to 2 GB (due to an integer overflow).

changelog_1084_li=Script tool\:Now, SCRIPT ... TO is always used (for higher speed and lower disk space usage).
changelog_1084_li=MVStore\:up to 65535 open transactions are now supported. Previously, the limit was at most 65535 transactions between the oldest open and the newest open transaction (which was quite a strange limit).
changelog_1085_li=Script tool\:Fix parsing of BLOCKSIZE parameter, original patch by Ken Jorissen.
changelog_1085_li=The default limit for in-place LOB objects was changed from 128 to 256 bytes. This is because each read creates a reference to a LOB, and maintaining the references is a big overhead. With the higher limit, less references are needed.
changelog_1086_li=Fix bug in PageStore\#commit method - when the ignoreBigLog flag was set, the logic that cleared the flag could never be reached, resulting in performance degradation. Reported by Alexander Nesterov.
changelog_1086_li=Tables without columns didn't work. (The use case for such tables is testing.)
changelog_1087_li=Issue 552\:Implement BIT_AND and BIT_OR aggregate functions.
changelog_1087_li=The LIRS cache now resizes the table automatically in all cases and no longer needs the averageMemory configuration.
changelog_1088_li=Creating a linked table from an MVStore database to a non-MVStore database created a second (non-MVStore) database file.
changelog_1089_li=In version 1.3.183, indexes were not used if the table contains columns with a default value generated by a sequence. This includes tables with identity and auto-increment columns. This bug was introduced by supporting "rownum" in views and derived tables.
changelog_1089_li=In version 1.4.184, a bug was introduced that broke queries that have both joins and wildcards, for example\:select * from dual join(select x from dual) on 1\=1

changelog_1096_li=In version 1.4.184, "group by" ignored the table name, and could pick a select column by mistake. Example\:select 0 as x from system_range(1, 2) d group by d.x;
changelog_1097_li=New connection setting "REUSE_SPACE" (default\:true). If disabled, all changes are appended to the database file, and existing content is never overwritten. This allows to rollback to a previous state of the database by truncating the database file.
changelog_1098_li=MVStore\:the default auto-commit buffer size is now about twice as big. This should reduce the database file size after inserting a lot of data.
changelog_1098_li=Issue 587\:MVStore\:concurrent compaction and store operations could result in an IllegalStateException.
changelog_1099_li=The built-in functions "power" and "radians" now always return a double.

changelog_1104_li=The database URL setting PAGE_SIZE setting is now also used for the MVStore.
changelog_1105_li=MVStore\:the default page split size for persistent stores is now 4096 (it was 16 KB so far). This should reduce the database file size for most situations (in some cases, less than half the size of the previous version).
changelog_1105_li=In version 1.3.183, indexes were not used if the table contains columns with a default value generated by a sequence. This includes tables with identity and auto-increment columns. This bug was introduced by supporting "rownum" in views and derived tables.
