Does fixed mean, pyspatialite was removed? How do I access or create SpatiaLite Layer using Python without pySpatialite? Sqlite3 does not provide any functionality.

Yes. Load the extension (see 6402160526e3176d1d41f422d6ecab59aa7ac68d).

I am very sorry, but what is meant by "load the extension"?
My old way was:
from pyspatialite import dbapi2 as sqlite
con = sqlite.connect(db_path)

The assumed new way is:
import sqlite3
con = sqlite3.dbapi2.connect(db_path)
con.enable_load_extension(True)
conn.execute("SELECT load_extension('mod_spatialite')")

Which does not work.
Loading any Spatialite-DB in the DB-Manager is also not possible anymore, which seems a little related.

@Jürgen Fischer & gcarillo, thanks for the effort, works now!
