If I take some code that was released under LGPL v2.1 and make modifications to it, what are my options for releasing that derived work again as open source?
I guess, one option would obviously be to release it again under LGPL v2.1. But that's about the only option I'm sure of.
Could I release my derived work under
- GPL v3
- LPGL v3
- MIT license
- Apache License 2.0
- any license listed as "GPL-Compatible" at the GNU website
without violating the LGPL v2.1?
