License

This project is currently licensed under LGPLv3 or any other later version, though I'm willing to consider other licenses if this doesn't match your needs. You may also contact me if you require additional commercial support.

Essentially, this means that you get the full source code and you can distribute and modify it, provided that you ship all modifications under the LGPL as well.

Can I use BoneCP in closed-source applications?

Yes, the LGPL does not impose GPL "viral" conditions on your own applications, whether they are for internal use or for distribution to users.

Will the licensing terms be changed in the future?

Any code that was once released under the LGPL cannot be "closed" again. The license that has been granted to you with the LGPL is perpetual and cannot be taken back.
