Plans for pandas 0.25.0 and pandas 1.0
by Joris Van den Bossche Nov. 12, 2019

Nov. 12, 2019

Hi all, We had some discussion about this on the in-person dev sprint end of June, and I thought it would be good to have some public record of this as well. A pandas 0.25.0 release is close (the RC was released earlier this month), see https://github.com/pandas-dev/pandas/issues/24950 For pandas 1.0, the current plan is to finally "just do it". The idea is that it should not take too long after 0.25.0, without additional major API changes (additions are fine of course) but with removing the current deprecated functionalities. Depending on how much feedback there is on 0.25.0 and on how smoothly it goes for removing deprecated stuff, we could (maybe optimistically) target September for that. Comments certainly welcome!

New website infrastructure
by Marc Garcia Sept. 25, 2019

Sept. 25, 2019

Somehow related to the work on the new website ( https://github.com/pandas-dev/pandas/pull/28014), I've been discussing with the Binder team, and looks like should be quite easy soon (with a Sphinx extension) to make all the documentation pages runnable with Binder, directly from the website (without opening the page as a Jupyter in mybinder). While they are very happy with the idea of having this is pandas, it's uncertain if the current infrastructure Binder has got, is able to handle all the traffic we would send. And scikit-learn is working on it too (today they added to the dev docs a link to mybinder to run the examples). I'm discussing with OVH (their infrastructure provider) on whether they'd be happy to provide a dedicated BinderHub specific to pandas (or may be we can have one for all NumFOCUS projects). We'll see how it goes, but wanted to let you know, so you're updated, and in case anyone is interested in participating in the discussions. Of course before any decision is made I'll open a discussion here or on GitHub. As part of the discussion I'm also trying to get a server for the website, and one for development stuff. Specfically for the dev docs (including rendered docs of every PR) and the GitHub app that will generate them. I guess it should be very easy to find a sponsor for these two servers (in exchange of a small note in the footer of the website, or something like that). Let me know if you have any comment, want to be involved or whatever. Cheers!

Dataframe summit @ EuroSciPy 2019
by Marc Garcia Sept. 15, 2019

Sept. 15, 2019

Hi there, Just to let you know that at EuroSciPy 2019 (in September in Spain) we will have a dataframe summit, to stay updated and coordinate among projects replicating the pandas API (other dataframe projects are more than welcome). Maintainers from all the main projects (pandas, dask, vaex, modin, cudf and koalas) will be attending. If you want to get involved (whether you can attend the conference or not), please DM me. More info: https://github.com/python-sprints/dataframe-summit Conference website: https://www.euroscipy.org/2019/ Cheers!

Version Policy following 1.0
by Tom Augspurger Sept. 14, 2019

Sept. 14, 2019

Split from https://mail.python.org/pipermail/pandas-dev/2019-July/001030.html Following 1.0, I think we stop outright breaking APIs. I think that stability will be welcome to users. We still have to decide how we deprecate APIs. The two options are 1. Rolling deprecations: Essentially what we do today: An API is deprecated in release 1.1.0 and can be removed in (say) 1.4.0. 2. SemVer: An API may be deprecated in 1.x.0. It can be removed in 2.0.0 Do people have preferences between the two? The (dis?)advantage of Semver is that all the API-breaking changes are restricted to a single releases. With rolling deprecations, the upgrades from any 1.x to 1.y should be smoother than 1.x to 2.x. Once we choose a strategy, we may want to formalize release schedules around it. Tom

Does a maintainer have a moment for an interview?
by Joseph Wagner Aug. 8, 2019

Aug. 8, 2019

Hi, I’m in the process of conducting interviews with experienced open source project maintainers, and I want to know if you’d be interested in taking 15 minutes to tell us about yourself and your role with pandas. To give you some more context; I’m working with a group of developers within Lambda School <https://lambdaschool.com/> to make a product related to repository data analytics and forecasting. If you have any prior experience with repo analysis tools that would be great to talk about as well. If you’re interested in helping us understand these issues better please feel free to let me know when you’re available and we can add that to our schedule. Our team normally uses Zoom <https://zoom.us/> for video calls, but if doesn’t work for you let me know and we can make adjustments. Regards, Joseph Wagner

Tidelift
by Joris Van den Bossche Aug. 8, 2019

Aug. 8, 2019

Hi all, We discussed this on the last dev chat, but putting it on the mailing list for those who were not present: we are planning to contact Tidelift to enter into a sponsor agreement for Pandas. The idea is to follow what NumPy (and recently also Scipy) did to have an agreement between Tidelift and NumFOCUS instead of an individual maintainer (see their announcement mail: https://mail.python.org/pipermail/numpy-discussion/2019-April/079370.html). Blog with overview about Tidelift: https://blog.tidelift .com/how-to-start-earning-money-for-your-open-source-project-with-tidelift. We didn't discuss yet what to do specifically with those funds, that should still be discussed in the future. Cheers, Joris
