  * Drop `getopt` usage, non-GNU/Linux environments are supported now.
  * Replace `-o`/`--opts=` parameters with `--curl-options`/`--curl-options=`.
    This alternative is more descriptive and it does not coincide with any of curl's parameters.
- * Stop auto-resuming downloads and don't overwrite files instead by default.
+ * Stop auto-resuming downloads and do not overwrite files instead by default.
    Safer alternative as otherwise curl can corrupt a file if the name clashes and the size of the existing one is smaller.
    One can easily change that behavior with `--curl-options="--continue-at -"`.
  * New `--dry-run` option: just print what would be invoked.
- * Choose HTTPS as a default protocol, in case there's none in the URL.
+ * Choose HTTPS as a default protocol, in case there is none in the URL.
  * Disable curl's URL globbing parser so `{}` and `[]` characters in URLs are not treated specially.
  * Implement support for `--`.
