I have updated two plugins I wrote a long time ago, which haven’t been updated in years, and were not fully compatible with the recent versions of WordPress. It felt very good, especially since I managed to rewrite both plugins in only a few hours, and looking at my old code made me realize how much I have learned.
I feel like I should do this more often.
I know the feeling. It’s amazing how much of our code “rots” isn’t it? You look at code you wrote even just a year ago and go, ‘What was I thinking doing it that way?’.
Exactly, you don’t get that stuff when updating plugins every day/week/month :)
