Numerous bit, string, array and system functions implemented
Standard-based access to generated keys

Between version 1.4.200 and version 2.0.202 there have been considerable changes, such that a simple update is
not possible.
The official way to upgrade is to do a BACKUP of your existing database USING YOUR CURRENT VERSION OF H2.
Then create a fresh database USING THE NEW VERSION OF H2, then perform a SCRIPT to load your data.
Version 1.4.200
Some new features:
JSON data type; JSON_OBJECT, JSON_ARRAY, JSON_OBJECTAGG, and JSON_ARRAYAGG functions; JSON predicate
TIME WITH TIME ZONE data type
BITNOT, LSHIFT, and RSHIFT functions
Named columns join (JOIN USING)
Type predicate (IS OF)
General logarithm function LOG(base, argument)
UNKNOWN literal and truth value tests
UNIQUE predicate
CURRENT_SCHEMA and CURRENT_CATALOG functions
Data change delta tables (OLD | NEW | FINAL TABLE)
CURRENT VALUE FOR sequence
EXECUTE IMMEDIATE command and QUOTE_IDENT function
Time zone specification (AT TIME ZONE | LOCAL)
ALTER TABLE tableName ALTER COLUMN IF EXISTS columnName
READ UNCOMMITTED, REPEATABLE READ, and SNAPSHOT isolation levels with MVStore engine
Incompatible changes:
MVCC setting (ignored since 1.4.198) now results in error
MULTI_THREADED setting is removed, MVStore engine is always multi-threaded, PageStore engine is always single-threaded
Statement.getGeneratedKeys() uses a FINAL TABLE semantics
Proleptic Gregorian calendar is used as required by the Standard
