For instance, there are some new “copy” features that allow you to copy text with applied styles and save the formatting for the user after pasting. Currently, I use v4.0.26 of TinyMCE in the existing app, so this update could bring some even greater utility for users.
I think what I’ll do is great a separate branch of the codebase, apply the update to the app, and take a look at how I feel about it for a week or so. It could solve a bit of problems in the future of the app even though it would create a minor update for existing users.
Still, thinking about moving forward with existing systems is always a good thing. There’s nothing worse than being locked into an old version or even a deprecated one that’s holding the app (and your users) back.
