Eclipse is getting stable releases four times a year (i.e. every three months). C/C++ support is also being actively maintained and is pretty fast these days.
Eclipse is one of the rare software suites which didn't get slower as the tech evolves. Yes, it's probably heavier when compared to 20 years ago, but it starts pretty quickly and works snappily. I'm a happy camper.
If only the Go tools didn't get discontinued, but alas. KATE/BBEdit + Gopls is a pretty nifty combo on Linux/macOS.
