{quote}Is "0.12.0-0" smaller than "0.12.0"?

No (I didn't know this until now...).
{code}
package_version("0.12.0-0") == package_version("0.12.0")
#> [1] TRUE{code}
One common practice is to add .9000 to the tail of the current released version
to represent "development version." So, in this case, the version would be
0.11.0.9000.

I guess you want to include "0.12.0" in the version string to indicate it's the
development version of "0.12.0." But, as far as I know, R has no nice way to do
that. Some possible choices are here:
# use "0.11.0.9000" for development, and "0.12.0" for release
# use "0.12.0" both for development and release
# use "0.12.0-0" for development, and "0.12.0-1" for release (c.f
