#release pyam v1.7.0 - Computing quantiles of scenario ensembles #release

Daniel Huppmann

Dear pyam user community,

I’m happy to announce a new release v1.7 of the pyam package!

# Highlight

- Add a feature to compute (weighted) quantiles for scenario data - see this tutorial!
- Implement a require_data() method for streamlined scenario validation
- Remove 'xls' as by-default-supported file format to harmonize behavior with pandas (but you can still use it, of course*)

[* simply install the package xlrd manually]

# API changes

The method compute_bias() was removed; please use compute.bias() instead.

# Dependency changes

This release removes xlrd as a required dependency; please install it explicitly for reading .xls files.
Please bump the minimum version of pandas to v1.2.0 to support automatic engine selection.

# Known issues

The latest release of the numpy package has some issues with the plotting library. For the time being, please stick with numpy<1.24.

# Join the Slack workspace?

If you want to ask questions or read tips-and-tricks from time to time on how to use pyam more effectively in your scenario analysis or data-viz work, maybe consider joining our Slack workspace?
