Main Addition:
You can share your tradeshops with more players. You can grant two permission levels: Owner and Member. Members can restock the shop (aka open the chest), whereas Owners can modify the sign and break the chest, as well as give/take permission to/from other players.

Notes:

• The current version is marked as BETA as significant changes/fixes were introduced. This means that there may be bugs.
• To report any of these, either post on the resource's discussion thread (discouraged!) or on the GitHub issue tracker (recommended!).
• If you wish to contribute by fixing bugs or adding new features, please open a pull request.
• This is a large update and tons of issues were fixed. Updating should be considered mandatory as soon as the BETA ends. You may update earlier though, which is recommended in production because this will get rid of several bugs and exploits.
• 1.8 support was dropped. Reasons were explained here.
