You created many problems for many peoples.

Problem 1
- ps/image-optimizer 1.2.0 requires psr/log 1.0.* -> no matching package found.
- iskander-g/beboss-library dev-master requires ps/image-optimizer ^1.0 -> satisfiable by ps/image-optimizer[1.2.0].
- Installation request for iskander-g/beboss-library dev-master -> satisfiable by iskander-g/beboss-library[dev-master].

Sorry but that's not true, and this PR is not related.

requires psr/log 1.0.* -> no matching package found.

This means that your installation is not able to pull the older 1.0.x tagged release, which is still there and usable. Furthermore, this package (as many, many others) follows SemVer, so ps/image-optimizer (and anyone else) can require ^1.0 and be happy with 1.0, or 1.1.0, without issues.

Thanks for answer! Interesting why so happens? My deploy system working above 2 year. it crashed today. 2 issues in image/optimize. the repo issue is disabled. Wrote here.

Your deploy system is probably bugged, it won't find psr/log 1.0.x which still exists. This PR or the 1.1.0 tag probably triggered it, but it's still a bug on your side.
