What is the meaning of "I've gotten over __ recently"?

A possible reading of the phrase "I've gotten over tool recently", is that the speaker was once very interested in tool, but has now lost interest in it. That he has gotten over it. A similar common usage would be, "I really loved jogging but I've gotten over it. It's too tiring".

Without further context and using only the fact that the author was not particularly fond of the tool, it could mean one of the following.

(1) He liked it very much in the past but dislikes it now.

(2) He found it difficult to use but has mastered it now.

(3) He had a bad time using it but is not troubled by it now.

Original sentence: https://stackoverflow.com/questions/57627/msys-vs-cygwin

I've gotten over cygwin recently. There's a lot of impedance mismatch between cygwin and the native platform

I read that as the user of cygwin no longer is annoyed with the shortcomings but initially it sounded to me as he no longer use it and has gotten over that fact - perhaps we ask him? @AdamMitz

Looking at the NOAD, I found two different phrasal verbs.

• to get over: to recover from an ailment or an upsetting or startling experience; to overcome a difficulty.
• to get [something] over: to manage to communicate an idea or theory.

In the sentence you wrote (where tool is referring to a software tool), I would understand to get over as to overcome the difficulty to use the tool.
