 ### Bug Fixes:
 
-- Missing variables in features were not always handled correctly in `predict()` with `newdata` not `None` in the presence of missing data, which would lead to an error. See [#246](https://github.com/s3alfisc/pyfixest/issues/246) for details.
-- Categorical variables were not always handled correctly in `predict()` with `newdata` not `None`, because the number of fixed effects levels in `newdata` might be smaller than in `data`. In consequence, some levels were not found, which lead to an error. See [#245](https://github.com/s3alfisc/pyfixest/issues/245) for details. Thanks to [@jiafengkevinchen](https://github.com/jiafengkevinchen) for the pointer!
-- Multicollinearity checks for over-identified IV was not implemented correctly, which lead to a dimension error. See [#236](https://github.com/s3alfisc/pyfixest/issues/236) for details.  Thanks to [@jiafengkevinchen](https://github.com/jiafengkevinchen) for the pointer!
-- The number of degrees of freedom `k` was computed incorrectly if columns were dropped from the design matrix `X` in the presence of multicollinearity. See [#235](https://github.com/s3alfisc/pyfixest/issues/235) for details.  Thanks to [@jiafengkevinchen](https://github.com/jiafengkevinchen) for the pointer!
-- If all variables were dropped due to multicollinearity, an unclear and imprecise error message was produced. See [#228](https://github.com/s3alfisc/pyfixest/issues/228) for details. Thanks to [@manferdinig](https://github.com/manferdinig) for the pointer!

 `PyFixest` is a Python implementation of the formidable [fixest](https://github.com/lrberge/fixest) package for fast high-dimensional fixed effects regression.
 
-The package aims to mimic `fixest` syntax and functionality as closely as Python allows: if you know `fixest` well, the goal is that you won't have to read the docs to get started! In particular, this means that all of `fixest's` defaults are mirrored by `PyFixest` - currently with only [one small exception](https://github.com/s3alfisc/pyfixest/issues/260).
