  modified:   storage/connect/JdbcInterface.java

- Change Version number and date
  modified:   storage/connect/ha_connect.cc

- Implement the test on connect_type_conv YES/NO
  modified:   storage/connect/jdbconn.cpp
  modified:   storage/connect/odbconn.cpp

- Fix MDEV-10520. Local schema was confused with remote schema
  modified:   storage/connect/tabjdbc.cpp
  modified:   storage/connect/tabodbc.cpp

- Fix crash when using mapped indices. Was trying to write in a mapped
  file declared as read only.
