I've neglected my rails application which runs my own website for many many years, mostly because it's a lot of work to keep upgrading rails especially when it comes to major version changes. Dependencies break and disapear, API's break, you need to rewrite a lot of code because new concepts and data structures gets introduced, etc. Anyway now I need to upgrade from rails 4.2 which was released 8 years ago to 7.0 which was released last year.
I still like to have written my own website because this way I can have exactly the functionality which I want, not someone else. But it's a lot of work.
