Checking when python packages were last updated

Question

Is there any way to check when were python packages last updated? I am getting some strange behaviour from one of the programs and I want to check if some undesired updates were performed. I am using conda as a package manager.

Answer 1

conda list --revisions

will show the changes and the date they were made. To search for a specific package, you can use grep:

conda list --revisions | grep numpy
