MineCraft 1.13 and above
Due to the significant changes in 1.13+, older versions of LWC are no longer supported. However, they can be downloaded from the LWCX Spigot Resource Page.
LWCX 1.9.7 (and above) for MineCraft 1.12 and prior.
LWCX 2.1.6 (and above) for MineCraft 1.13 and above.
To upgrade your database from LWCX 1.9.x, simply download the latest version of LWCX (2.1.6 or higher) and place it in your plugins folder. Make sure that no other version of LWC is installed. Then, simply start the server, and your database should automatically be upgraded. Warning: It is highly recommended to make a backup of your database before performing the upgrade (ie. find "lwc.db" in plugins/LWC and copy it somewhere). Once the database is upgraded, it should fully support 1.13. However, please keep in mind that this is a permanent upgrade, and you cannot use the database on versions prior to 1.13 once you have upgraded it.
The default configuration for LWCX 2.1.0 (or higher) has been updated to fully support 1.13. It includes many new blocks, as well as blocks that were renamed. On a fresh install of LWCX, these configuration files will be automatically created for you. If you are using an outdated version of LWCX (prior to 2.1.0), you will need to delete or move your core.yml and magnet.yml. Once you do so, the server will automatically create a new one for you when you start your server.
