We started on Rails 3.2 and on Rails 8 now. Some upgrades were harder than others, but they never warranted anything close a rewrite.

Rails 2 to 3 was a bit more involved than others, also Ruby 1.8 to 1.9 !

But ultimately it got better IMO, indeed.

Not a Ruby/Rails person, but from a quick look there are still APIs named exactly the same between those versions. Very nice to see

On the other hand, Laravel decided to change from snake_case to CamelCase between versions 3 and 4, just because. Literally 0% compatibility

They also completely changed the project structure recently, which made 100% of previous tutorials and examples on the internet obsolete.

Ouch, I haven’t kept up to date. Have any links explaining? Thanks

Things which you were able to configure in the past, are now hidden. The meaning of many files (e.g. bootstrap) is now completely different. All different service provider classes are gone.
