 - The driver incorrectly applied a timeout hint received from the server to both read and write I/O operations.
   It is now only applied to read I/O operations.  
   In turn, a new configuration option `connection_write_timeout` with a default value of `30 seconds` is introduced.
-- Adjust `repr` string representation of spatial types to conform with Python's recommendations.
+- Adjust string representation(s) of several types:
+  - `SummaryCounters`: `repr` and `str` to conform with Python's recommendations.
+  - `Point` and its subclasses: `repr` to conform with Python's recommendations.
