Registration pull request created: JuliaRegistries/General/8480

After the above pull request is merged, it is recommended that a tag is created on this repository for the registered package version.

This will be done automatically if Julia TagBot is installed, or can be done manually through the github interface, or via:

git tag -a v0.4.7 -m "<description of version>" 2bb8dae5d46fb5dbfa916a50e38282c1e50df40d
git push origin v0.4.7

Also, note the warning: Version 0.4.7 skips over 0.4.6
This can be safely ignored. However, if you want to fix this you can do so. Call register() again after making the fix. This will update the Pull request.
