• Tree Feller will now break blocks within the limit instead of refusing to fell the entire tree (partial big tree destruction)
• Mangrove trees resulting from growth are now marked as natural (existing trees marked unnatural before this update will not be retroactively fixed)
• Fixed a bug removing comments from configs (see notes)
• Fixed mouse-hover tooltip windows (thanks Greymagic27)

NOTES:
Regarding the secure chat feature Minecraft rolled out, once APIs have updated I will look into rolling support for that into admin/party chat.
Comments should no longer get removed from config but I haven't added any code to add missing comments back in, for now if you want comments you can delete the config file to regenerate it (sorry for the inconvenience)
