- Make fields and methods private where possible
- Add missing Javadocs
- Remove @throws Javadocs (all other languages don't have throws, and it doesn't help much documenting them)
- Use camel case for metaData
- Remove initializing to default values (null, 0, false) because that's anyway done automatically
- Remove @Override to let it compile with JDK 5
- Mark as 'work in progress'

- Add class level Javadoc documentation (I hope it's somewhat correct)
- Make fields private if possible
- Enable the trace option when running in standalone mode
- Instead of System.out.println(), use trace()
- Remove 'verbose' flag, use the trace flag instead
- Remove @Override so it can be compiled with JDK 5 (so that the nightly build works)
- Use { .. } even for single line blocks - this is the code convention used in H2 (so that insertion of a new line of code anywhere is always "safe")

- Improve Javadoc documentation
- Javadoc: add missing documentation for <T> (the IDE or checkstyle flags this) 
- Javadoc: removed trailing whitespace
- Remove @Override tag because this won't compile with JDK 5
- Flag that there is something wrong (what if 'y' isn't a Number? anyway instanceof should be avoided)

- Improve Javadoc documentation
- Javadoc: removed unpaired <p>
- Javadoc: removed shouting (bold, caps "MUST")
- Javadoc: document parameters
- Javadoc: no need to write Return in a @return tag
- Javadoc: make correct sentences, not sentence fragments ('Default Db Upgrader.' is not a sentence)
- Remove @Override tag because this won't compile with JDK 5
- Methods in public interfaces don't need to be declared public (Checkstyle detects this, please use Checkstyle as documented)

- Improve Javadoc documentation
- Add Javadoc documentation (each class and interface method should be documented)
- I didn't want to use MessageFormat but I guess that's not an important change

- add missing //## Java 1.5 end ##
- according to checkstyle final static fields names are all caps
- remove trailing spaces (please configure the IDE accordingly)
- add missing space after comma (please configure checkstyle)

Please note that counter++ is counter.getAndIncrement() and not counter.incrementAndGet(). But I guess this doesn't make a difference here.

MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.

Linked tables / MS SQL Server: if the tables were created in mixed case in MS SQL Server, then the identifiers in the linked tables were case sensitive (in H2).

H2 Console: opening a MS SQL Server database is now faster. Also, listing the database meta data sometimes resulted in an exception.

MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.

Some people reported NullPointerException in FileObjectDiskMapped. The most likely explanation is that multiple threads access the same object at the same time. Therefore, the public methods in this class are now synchronized.

Building only the documentation (without compiling all classes) didn't work, specially: ./build.sh clean javadocImpl.

The pseudo-column "_ROWID_" now supports insert, update, and merge (only enabled for version 1.3.x).

The new CSV option feature introduced in version 1.3.150 didn't support spaces. Now the escape mechanism is changed to support it.

Improved error detection when starting a server with invalid arguments, such as "-tcpPort=9091" or "-tcpPort 9091" (as one parameter) instead of "-tcpPort", "9091".

The function JAVADECODE ignored characters after a non-escaped double quote. This is no longer the case.
