+[Full Changelog](https://github.com/DataONEorg/d1_python/compare/2.4.2...3.2.0)
+
+* DataONE Generic Member Node (GMN)
+
+  * Added web interface for GMN
+    * MN organization highlighted with logo and description 
+    * Opening any link at or below the BaseURL of GMN provides a way to reach all publicly available information on the MN. This includes links that do not go to valid endpoints, or are in other ways invalid
+    * Functionality includes
+      * Links to profile pages on Search for subjects and other MNs
+      * Resolve objects on CN, download object from MN, view System Metadata
+      * Browse object list and log records, paging forwards and backwards
+      * Static links to areas of interest for DataONE
+
+  * Added Apache, Postgres and Python version numbers to GMN status page
+  * Reading from the GMN status page with without a browser now returns an XML doc. No need to scrape the page for version numbers and other status information
+  * Added multiprocessing to GMN bulk importer
+    * 10x speedup seems likely in latency bound systems
+
+  * Added more validation of GMN settings
+  * Added migrations to generate Postgres indexes for default sorting  
+    * Suprisingly, Django does not generate indexes for default sort ordering specified when using the ORM
+
+  * Reconfigured logging to take advantage of Django's support for rotating logs, much like logrotate does. Maximum space to use for logging is now a config setting.
+  * Other usability improvements (see log)
+
+* GMN deployment

+
+    * Factored repeated paths out 
+
+* Documentation
+
+  * Fixed documentation build warnings and formatting
+  * Added SSL/TLS troubleshooting doc, misc other background information
+  * Restructured doc layout
+  * Refactored shell commands into larger blocks to reduce copy/paste
+  * Added more checking and related logic to the blocks to automatically handle more filesystem / OS variations
+  * Added Copy buttons for all shell blocks
+  * Added docs for
+    * How to set up GMN using APT instead of PyPI dependencies
+    * How to set up multiple MNs on a single GMN instance
+    * How to perform automatic upgrades within GMN 3.x
+    * How to cluster tables by index in Postgres to improve GMN perf
+
+  * Added missing glossary entries
+  * Upgraded to Sphinx Better theme 0.1.5
+
+* DataONE Client and Common Libraries
+
+  * Refactored to improve functionality and take advantage of new functionality in the underlying dependencies
+  * Standardized logging in d1_python
+  * Consistently use timezone aware datetime objects
+  * Removed automatic caching (cachecontrol) in d1_client
