 The function `plot_iso()` is a convenience function for debugging and
 testing.

 The isolining and isobanding algorithms have no problem with larger
 datasets. Let’s calculate isolines and isobands for the volcano dataset,
 convert to sf, and plot with ggplot2.

-This is a minor update removing the testthat compile-time dependency and fixing errors on Solaris.
+Questions in response to the previous submission:
+
+> Why is such a quick update needed? Please explain. Please also re-read the CRAN policies about submission frequency.
+
+This update removes the compile-time dependency of testthat, so that the package can be installed without having to install testthat and all its down-stream dependencies. This was requested by the ggplot2 team as ggplot2 depends on isoband.
+
+This request was made a few days ago and I'm updating the package in response to the request: https://github.com/wilkelab/isoband/issues/19
+
+Since the update significantly reduces load on CRAN mirrors, it seems worthwhile to do it as soon as possible.
+
+I have also fixed the outdated link that was identified in the previous submission.
 
 ## Test environment
 * ubuntu 20.04, devel and release
