Hi @jescalada! Thanks for your contribution.

I notice a couple of things that need attention:

Missing issue link: Could you please link this PR to an existing issue using "Fixes #N", "Closes #N", or "Resolves #N" in the description? If there isn't an existing issue for this change, please create one first as mentioned in our contributing guidelines.

Description could be clearer: While I can see this is about bumping to version 1.3, it would be helpful to have a bit more detail about what specific changes are being made and why. What does "simulate feature being added" mean in this context?

Looking forward to getting this sorted out!
