+ * #98: Support for Borg --keep-secondly prune option.
+ * Use Black code formatter and Flake8 code checker as part of running automated tests.
+ * Add an end-to-end automated test that actually integrates with Borg.
+ * Set up continuous integration for borgmatic automated tests on projects.evoworx.org.
+
+1.2.6
+ * Fix generated configuration to also include a "keep_daily" value so pruning works out of the
+   box.
+
+1.2.5
+ * #57: When generating sample configuration with generate-borgmatic-config, comment out all
+   optional configuration so as to streamline the initial configuration process.
+
 1.2.4
  * Fix for archive checking traceback due to parameter mismatch.

+Note that while running borgmatic itself only requires Python 3+, running
+borgmatic's tests require Python 3.6+.
+
+If when running tests, you get an error from the
+[Black](https://black.readthedocs.io/en/stable/) code formatter about files
+that would be reformatted, you can ask Black to format them for you via the
+following:

+### End-to-end tests
+
+borgmatic additionally includes some end-to-end tests that integration test
+with Borg for a few representative scenarios. These tests don't run by default
+because they're relatively slow and depend on Borg. If you would like to run
