Hi Everyone, hopefully a more timely summary this week. As usual, if this 
is helpful for you, you are welcome to participate, and edit the DropBox 
summary before I send it to the mailing list. 

See http://bit.ly/JupyterTeamMeetingArchive to see all the notes, the 
youtube link should soon be available if you want to actullay listen to the 
meeting. .

IPython (Matthias) 

I’m slowly ramping up IPython development again. We haven’t had a release 
in quite some time, and had a couple of bugfix. I’ll try to cut a 6.2/5.5 
in the next few weeks ; with few new features.

MrMeeseeks (or bot) is smarter (since yesterday/this morning) and will for 
the IPython repository, automatically backport PRs that are milestoned 
5.whatever, no need to ask him to do so. I plan to work with Chris H. on 
Friday to try to bring that to the matplotlib org. Feel free to join if you 
have ideas for the bot. 

Thomas is suggesting removal of old, unused IPython labels; it will 
discared some information about old issues. See thread 
<https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/jupyter/6sBaT4JDWmo/JzpyBsjOEQAJ>,
 
if you want to express your (dis)agreement:

   - backport-{0.12.2 … 2.1} (We later switched to using milestones to 
   indicate backports) 
   - console (redundant with zmq-console) 
   - emacs 
   - forward_port 
   - hacktoberfest 
   - latex 
   - py3k 

Governance (Matthias) 

Please read about the LICENSE guideline discussion, if you haven’t, and are 
interested in the tricky buisness of doing the right thing (not alway easy):
jupyter/governance#37 <https://github.com/jupyter/governance/issues/37>
Documentation (Jessica) 
   
   - Looking for feedback for demo before we present at Strata NYC 
   - Hoping to get feedback from UX studies regarding Jupyterlab FAQ 
   - Would like to share language between docs FAQ and Jupyterlab FAQ
   https://github.com/jupyterlab/jupyterlab/pull/2954
   https://github.com/jupyterlab/jupyterlab/pull/2785 

Notebook (Grant) 
   
   - Grant has returned from Indonesia and will push for 5.1 release this 
   week 
   - 5.1.0rc3 is available for testing. 

Nbconvert (M) 
   
   - released 5.3.1 (fixes the license issues to include in Manifest.in) 
   both on pypi and conda-forge 
   - conda-forge build includes a change to noarch 
   <https://github.com/conda-forge/conda-smithy/issues/485> which could(?) 
   mess with entrypoints, if anyone runs into any issues with the conda-forge 
   build (especially if using Windows…)
      - Honestly, this is less my expertise 
      - noarch means “no architecture”. Usually a package is built 
      separately for each “architecture”, e.g., a build for Windows, a build 
for 
      Linux, a build for OS X, etc. The noarch flag, possible on packages that 
      are pure python, etc., means that you can build only a single package and 
      it will work across all of the architectures. 
   
Nbformat (M) 
   
   - we now explicitly document cell.metadata.name’s uniqueness & its 
   limitations
      - doc pr: https://github.com/jupyter/nbformat/pull/117 
      - summary: we can’t verify uniqueness across cells with the json 
      schema. 
      - we should look into implementing (efficient) checks in our 
      front-ends for name uniqueness
         - no prs to link 
         - what should the priority of this be? 
         - where this should be implemented? 
            - *Python* in nbformat? 
            - *javascript* in notebook? jupyterlab? nteract? 
         - tags behaviour and conventions
      - pr (on notebook): https://github.com/jupyter/notebook/issues/2826
         - issue should stay on notebook until we come to some kind of an 
         agreement 
         - this explicitly introduces the raises-exception tag as having a 
         jupyter specific meaning (has not been released yet but will be with 
5.1) 
      - how should we come to a consensus about the appropriate use of 
      tags? Do we have a mechanism for establishing this?
         - issues seem to be a bad at establishing consensus… or even 
         getting a general feel for people’s attitudes (as opposed to an 
ongoing 
         conversation) 
      - How can we implement hooks for people to assign tags to 
      functionality in a live javascript context?
         - are traitlet (json) config files enough? 
         - do we want to somehow include them with the notebooks themselves 
         (since they otherwise will not be consistent once shared)? 
      - Do we want to use tags in a different way than nbconvert uses them 
   
JupyterLab (Steve, Darian) 
   
   - Continued work towards the beta, nothing significant to report. 

Jupyter widgets (Jason) 
   
   - We are working on a 7.0.1 release 
   <https://github.com/jupyter-widgets/ipywidgets/milestone/16> fixing some 
   issues that were reported, adding more documentation, etc. We hope to 
   release 7.0.1 this week. 

Services (Peter) 
   
   - There have been many recent PRs in docker-stacks with requests to add 
   and update libraries/languages and support other options (
   https://github.com/jupyter/docker-stacks/issues/464, 
   https://github.com/jupyter/docker-stacks/issues/454).
      - Breakage occurs because of the complexity of software and options 
      now available. 
      - We could start putting more testing around the images (
      https://github.com/jupyter/docker-stacks/issues/406) 
      - We’re could also discuss ways of getting these images back to a 
      small “starter kit” set and providing users with a way to build their own 
(
      https://github.com/jupyterhub/binderhub/issues/101#issuecomment-328358104
      ) 
   - Kernel Gateway 2.0.1 released upon user request with one bug fix.
      - It had been a few months since last release and there was nothing 
      else in flight. 
      - A discussion kicked off about shifting some of the KG features back 
      to notebook server (
      https://github.com/jupyter/kernel_gateway/issues/259). 
      - conda-forge folks requested that we try *noarch: python.* Looks 
      like it worked: 
      https://github.com/conda-forge/jupyter_kernel_gateway-feedstock/pull/7 
   - nbviewer has a handful of PRs that I haven’t had time to review 

JupyterHub (Min, Carol) 
   
   - Please send any feedback on JupyterHub 0.8 beta #5 (which was released 
   last week - changes from 0.8.0b4 
   <https://github.com/jupyterhub/jupyterhub/compare/0.8.0b4...0.8.0b5>). 
   Thanks!
