What this means

The LGPL v3 is a copyleft license that allows you to:

• Use Odysseus commercially
• Modify the source code

• Disclose source: You must make the source code available when distributing the software
• License and copyright notice: You must include the original copyright and license notice
• State changes: If you modify the library, you must indicate that changes were made
• Same license: Modifications to the library must be released under the LGPL v3

The LGPL allows proprietary software to link to the library without requiring the proprietary code to be open-sourced, making it more permissive than the full GPL while still protecting the library itself.
