CraftBay

• Add config.yml option: denydoublebid: If true, players can no longer place several bids in a row within the same auction.
• Preserve comments in the config.yml file for better documentation.

These changes will affect several configuration files:

• config.yml: denydoublebid: false
• lang/*.yml: auction.bid.doublebid: <String>

You can regenerate these files by deleting them before the plugin is loaded, or add the missing entries by hand.
