Hi everyone,

I’m happy to announce a new release of ibis, a pandas-like deferred expression library. We recommend that all users upgrade to version 0.11.2.

One thing to note is that now pip install ibis-framework will install the minimum set of dependencies. Additional dependencies can be installed with pip extras:

pip install ibis-framework[all]  # for everything

# for individual backends/features
pip install ibis-framework[sqlite]
pip install ibis-framework[postgres]
pip install ibis-framework[impala]
pip install ibis-framework[pandas]
pip install ibis-framework[visualization]
pip install ibis-framework[kerberos]

You can combine features as you see fit. For example:

pip install ibis-framework[impala, kerberos]

to get ibis plus dependencies for running ibis with impala and kerberbos.

A conda-forge patch was just merged to update conda-forge builds for v0.11.2. After conda-forge builds finish you can update ibis as follows:

conda install ibis-framework=0.11.2 -c conda-forge

Here’s a short summary of new features in 0.11.2:

Experimental support for execution against pandas DataFrames (install with pip install ibis-framework[pandas]).
Support for schemas (of the namespace variety) in the PostgreSQL backend
Support for missing SQLite functions such as variance, standard deviation, sqrt, exponentiation and regular expression functions.
Graphviz visualization of ibis expressions, including support for Jupyter notebook rendering (install with pip install ibis-framework[visualization], requires a working graphviz installation).

There are also a slew of bug fixes that went into this release.
