Links for mobile browser comparisons break over time

[RByers]

I appreciate that it's not currently practical to keep data for old verisons of Chrome on Android (#3518) but this has the unfortunate side-effect of making browser comparison links that once worked, fail over time. Eg. https://caniuse.com/?compare=and_chr+111,ios_saf+16.4&compareCats=all now doesn't show any Chrome at all since the data for m111 is now gone.

Could the site perhaps default to selecting the latest version when the version in the URL is known to have been expired? Alternately perhaps the version selection UI should offer a "latest" option which results in a URL that stably refers to the latest available versions?

I've implemented a partial solution to this issue, for now if you leave out the version number in the URL it will automatically pick the current version, e.g. https://caniuse.com/?compare=and_chr,ios_saf

No UI for this just yet but you can start constructing URLs like this.

Excellent, thank you!
