Full Changelog: v0.3.1...v0.3.2

v0.3.1

Internal

• Minor updates to internal code and some unit tests to match forthcoming
  updates to marginaleffects 0.10.0. The latter update also brings some notable
  performance improvements to emfx().

Other

• Some documentation improvements.
• The Examples have been wrapped in \dontrun to avoid triggering CRAN NOTEs on
  Windows for exceeding 5 seconds execution time. Note that the package homepage
  still runs these Examples if users want to inspect the output online.

v0.3.0

New features and enhancements

• Support for estimating heterogeneous treatment effects via the new
  etwfe(..., xvar = <xvar> argument (#16, thanks to @frederickluser).
  Automatically extends to emfx() via the latter's by_xvar argument (#21).
  More details are provided in the dedicated "Heterogeneous treatment effects"
  section of the vignette and help documentation

• The new emfx(..., collapse = TRUE) argument can substantially reduce
  estimation times for large datasets (#19, thanks @frederickluser). This
  performance boost does trade off against a loss in estimate accuracy. But
  testing suggests that the difference is relatively minor for typical use cases
  (i.e., results are equivalent up to the 1st or 2nd significant decimal place,
  and sometimes even better). Please let us know if you find edge cases where this
  is not true. More details are available in the dedicated "Performance tips"
  section of the vignette and help documentation, including advice for combining
  collapsing with emfx(..., vcov = FALSE) (which yields an even more dramatic
  speed boost but at a cost of not reporting any standard errors).

• Users can now use a 1 on the fml RHS to indicate that there are no control
  as part of the etwfe call, e.g. etwfe(y ~ 1, ...). This provides a second
  way of doing this, alongside the existing 0 option, e.g. etwfe(y ~ 0, ...)

Bug fixes

• Internal code and tests have been updated to account for some upstream
  breaking changes in marginaleffects 0.9.0 (#20, thanks @vincentarelbundock).
  From the user side, the most notable changes are that we no longer have to call
  summary() on emfx objects for pretty printing, and that the (former) "dydx"
  column of the resulting object is now named "estimate". These changes are
  reflected in the updated documentation.

Other

• Various documentation improvements. For example, the aforementioned sections
  on Heterogeneous TEs and Performance tips. I have also removed some warnings
  about the use of time-varying controls (#17). In truth, I can't quite recall why
  I included these warnings in the first place and testing confirms that it does
  not appear to pose a problem for the ETWFE framework. Thanks to Felix Pretis for
  prompting me to revisit this implicit restriction, including forwarding some
  relevant correspondence with Prof. Wooldridge.

• data.table is added to Imports and thus becomes a direct dependency. It
  was already an indirect dependency through marginaleffects.

• It's now possible to install the development version of the package from
  R-universe. Details are provided in the README.

v0.2.0
