Recent observational efforts have presented new results concerning (linear) polarization variations as a function of time as well as wavelength that have considerable impact on WR star models:

Polarimetry throughout orbital phase has provided inclinations of double-line spectroscopic binaries containing WR stars with O star companions, thus improving our understanding of the masses and evolution of WR binaries (Schulte-Ladbeck 1989, A.J. 97, 1471). New binary-model calculations were presented at the meeting and continuing comparison with observations should prove productive.
