<p dir="auto">Thank you all for the interesting conversation. Am I correct in understanding the following?</p>
<ul dir="auto">
<li>The main OpenStreetMap web app runs Ruby 3.4.5.</li>
<li>This is an FOSS app that anyone can install and run on their own, and for this reason OSM wants to support a certain infrastructure flexibility, in this case with Ruby versions.</li>
</ul>
<p dir="auto">If the above is correct, then having people developing under different rubies can be useful. CI runs several versions, but test coverage is not great so things can slip.</p>
<p dir="auto">Having said that, I do feel a bit weird about the misalignment between development and production. Although Ruby is relatively stable, incompatibilities do happen. Having <code class="notranslate">.ruby-version</code> will not affect your development if you don't use any of these version management tools. However, if you do use them and you prefer developing with a different Ruby version, then perhaps there's a problem: the tool may get in the way and push you to use the given version (with some it can be configured away, but it's still a friction).</p>
<p dir="auto">As for the choice of minimum Ruby version, am I correct that the supported versions of Ruby depend on the Rails version? Rails 8.0 supports Ruby 3.2+, so I'm guessing the support grid will change when upgrading to a new Rails in the future.</p>
