We just got notice today about cubeSQL 5.5:
After several months of development we are proud to announce the immediate availability of cubeSQL 5.5. cubeSQL is probably the most stable version we have ever released, it also includes several performance related changes that you'll immediately noticed when compared to older versions. SSL support has been greatly improved and thanks to Tino Gruse from Roth Soft AG we now have a complete and detailed guide about how to Setup SSL.
You can find more details in our blog post: Announcing cubeSQL 5.5
We support cubeSQL with our SQLiteExtension.
