MySQL (InnoDB) is now an option that can be used instead of SQLite and code has been re-written to use this, if set, wherever possible.

Why? Because if running massive runs with 10+ threads etc SQLite simply is too prone to errors (and corruption) and isn't a great choice for say 30-100 000+  runs, something that is quite feasible when running 10+ threads and date ranges that span just 3-4 months.

So this became somewhat of a problem and has been solved by letting the user choose MySQL as the database.
Requires the user to set this up in its user.config.php (see new sample.config.php).

Using MySQL is also now the recommended way to run Gabby if you aren't just testing things out.

This also introduces a breaking change -- the naming scheme for the database names (SQLite as well) has changed.
This mean that any old runs/database you have for SQLite will now not show up at all since GAB will not recognize these as valid databases (or it will error out).

To solve this use the included tool Compatibility Fix. Currently this will rename your SQLite databases to the new naming scheme automatically.
You'll find it under <your install directory>/tools e.g. localhost:80/gab/tools

to update do:
git pull

or to install the new version to an entirely different dir create a new one and do:
git pull https://github.com/tommiehansen/gab.git

The database name is not required in     Example for mysql: '127.0.0.1:3306,TommieHansenIsTheBest,MySuperPassword' ?
I am getting error:

MySQL db connection test
FAIL Could not connect to MySQL database, error message:
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No address associated with hostname

This more have to do with your settings for your database server (and PHP) so you should Google/look into such a problem.
