I'm pretty sure there is no comprehensive list of outdated repo software anywhere, so why not create one here?
I know when Mint 19 lands, a lot of available software will be more up to date for those that upgrade. Until then, and for those that stay with 18.x even after 19 is available, maybe this thread can serve as an unofficial list of what to steer clear of in the official repositories.
I'll do my best to regularly update this post to include software that should be avoided and, where applicable, the recommended or most popular alternative.
Please offer your suggestions/opinions to help make this list as useful as possible.
