I Optimized My Bump Version Tool and Made It 1,000,000x Faster Than Its Python Counterparts.

Hello again, fellow Rustaceans, Pythonistas in denial, and the three people on earth who genuinely enjoy reading version bumper release notes 👋!

If you were here for my last post, where I rewrote bump2version in Rust and declared it ~10,000x faster than the Python CLI, you may recall that I ended it with a vague threat about future benchmarks. The Mossad agents who consulted on the architecture wrote "this is not over" in the margin of their whiteboard. I ignored it.

I should have listened.

Because in the weeks since that post, I went back in. Deep in. I committed crimes against cargo build that will haunt me during thunderstorms. I --release'd things that should not be --release'd. I made Claude hallucinate a performance chart at 3AM and then used it to motivate myself.

The result: bump2version 0.2.1.
