 ## Changelog
 
-### dev (requires minimum JupyterHub 0.7.2 and Python 3.4)
+### dev (requires minimum JupyterHub 0.9 and Python 3.5)
 
 Added (user)
 
 * Add Jinja2 templating as an option for all scripts and commands.  If '{{' or `{%` is used anywhere in the string, it is used as a jinja2 template.
 * Add new option exec_prefix, which defaults to `sudo -E -u {username}`.  This replaces explicit `sudo` in every batch command - changes in local commands may be needed.
 * New option: `req_keepvars_extra`, which allows keeping extra variables in addition to what is defined by JupyterHub itself (addition of variables to keep instead of replacement).  #99
 * Add `req_prologue` and `req_epilogue` options to scripts which are inserted before/after the main jupyterhub-singleuser command, which allow for generic setup/cleanup without overriding the entire script.  #96
-* SlurmSpawner: add the `req_reservation` option.  #
+* SlurmSpawner: add the `req_reservation` option.  #91
+* Add basic support for JupyterHub progress updates, but this is not used much yet.  #86
 
 Added (developer)
 
 * Add many more tests.
 * Add a new page `SPAWNERS.md` which information on specific spawners.  Begin trying to collect a list of spawner-specific contacts.  #97
+* Rename `current_ip` and `current_port` commands to `ip` and `port`.  No user impact.  #139
+* Update to Python 3.5 `async` / `await` syntax to support JupyterHub progress updates.  #90
 
 Changed
 
-* PR #58 changes logic of port selection, so that it is selected *after* the singleuser server starts.  This means that the port number has to be conveyed back to JupyterHub.  This requires the following changes:
+* PR #58 and #141 changes logic of port selection, so that it is selected *after* the singleuser server starts.  This means that the port number has to be conveyed back to JupyterHub.  This requires the following changes:
   - `jupyterhub_config.py` *must* explicitely import `batchspawner.api`
-  - If you override `Spawner.cmd`, note that the default command is now `batchspawner-singleuser`, not the default `jupyterhub-singleuser`.  This is to add a hook to report the port number back to the hub.
+  - Add a new option `batchspawner_singleuser_cmd` which is used as a wrapper in the single-user servers, which conveys the remote port back to JupyterHub.  This is now an integral part of the spawn process.
   - If you have installed with `pip install -e`, you will have to re-install so that the new script `batchspawner-singleuser` is added to `$PATH`.
-* Update minimum requirements to JupyterHub 0.8.1 and Python 3.4.
+* Update minimum requirements to JupyterHub 0.9 and Python 3.5.  #143
 * Update Slurm batch script.  Now, the single-user notebook is run in a job step, with a wrapper of `srun`.  This may need to be removed using `req_srun=''` if you don't want environment variables limited.
 * Pass the environment dictionary to the queue and cancel commands as well.  This is mostly user environment, but may be useful to these commands as well in some cases. #108, #111  If these envioronment variables were used for authentication as an admin, be aware that there are pre-existing security issues because they may be passed to the user via the batch submit command, see #82.

 Fixed
 
 * Improve debugging on failed submission by raising errors including error messages from the commands.  #106
