 # Qurro changelog
 
+## Qurro 0.8.0 (date TBD)
+### Features added
+- Add an option to Qurro's visualization interface to exclude metadata columns
+  from the "sample plot data" output TSV
+  ([#306](https://github.com/biocore/qurro/issues/306),
+  [#313](https://github.com/biocore/qurro/pull/313)).
+  - This should make it easier to merge the sample log-ratios exported from
+    Qurro with a sample metadata file -- since now these metadata columns won't
+    be duplicated, which would cause problems. (This problem comes up in
+    [Gemelli](https://github.com/biocore/gemelli)'s tutorials.)
+### Backward-incompatible changes
+- Switched the required pandas version from `>= 0.24.0, <1` to `>= 1`.
+  This makes Qurro now compatible with QIIME 2 versions `>= 2020.11`!
+  - However, this change removes support for older QIIME 2 versions. (It may be
+    possible to get this version of Qurro installed into an older QIIME 2
+    environment, but we do not explicitly support this.)
+  - Notably, Songbird has not yet made the shift to pandas `>= 1`, so Songbird
+    and Qurro will need to be installed into separate environments; the "Red
+    Sea" example notebook details this process.
+### Bug fixes
+### Performance enhancements
+### Miscellaneous
+- Improve various parts of Qurro's code to remove various warnings (for
+  example, about certain things being deprecated).
+- Update Qurro's example notebooks:
+  - Updated the "Red Sea" notebook to explain how to use
+    Songbird and Qurro in different conda environments.
+  - Updated the "ALDEx2" notebook to explain how we recommend installing ALDEx2
+    nowadays.
+- Updated the documentation to refer to the published version of the Mackerel
+  data's paper ([Minich et al. 2020](https://journals.asm.org/doi/full/10.1128/mSphere.00401-20)).
+- Ported Qurro's continuous integration from Travis CI to GitHub Actions
+  ([#316](https://github.com/biocore/qurro/issues/316)).
+- Improved Qurro's continuous integration in multiple ways:
+  - Test on multiple QIIME 2 versions.
+  - Test the standalone Qurro functionality on multiple Python versions.
+  - Test the standalone Qurro functionality in a non-QIIME-2 environment
+    (similar to EMPress' "standalone" CI).
+- Updated the development documentation regarding the minimum QIIME 2 version,
+  incompatibilities between `black` and `click`, etc.

+### When running QIIME 2, Qurro, etc. I get `TypeError: __init__() got multiple values for argument 'obj'`
+
+This happens due to a [Click](https://click.palletsprojects.com/en/8.1.x/)
+version being installed that is unsupported by
+QIIME 2. See [this q2cli issue](https://github.com/qiime2/q2cli/issues/259) for
+context. This can come up in development because one of Qurro's development
+dependencies is
+[Black](https://github.com/psf/black), and later versions of Black can rely
+on Click 8 (and as of writing QIIME 2 doesn't seem to support Click 8 yet).
+
+If you run into this error, you can probably get around it by installing an
+older version of Black, although earlier versions of Click might disagree with

+yet that I know of (short of pinning Black to an earlier version and
+reformatting all the Python code accordingly...), but hopefully when QIIME 2
+supports Click 8 the problem will vanish.
