Semantic Version Bump Generator
Bumping a version number sounds simple until you accidentally ship a 1.5.0 when you meant 2.0.0, or forget to reset the patch count after a minor bump. Semantic versioning has exact rules: a major bump resets minor and patch to zero, a minor bump resets patch, and a patch bump increments only the last digit. This tool applies those rules mechanically so you can verify the correct next version at a glance. Enter your current version string in the version field — a leading v is stripped automatically. Choose the bump type: major for breaking changes, minor for new backward-compatible features, or patch for fixes. The output shows both the input version and the computed next version side by side, with the bump type labeled, so it is easy to copy and confirm. Paste the result into your package.json, cargo.toml, or git tag command. The tool handles only the core major.minor.patch triple. Pre-release labels like -beta.1 and build metadata like +build.2 are not parsed or preserved — manage those separately if your workflow uses them.

FAQ
what do major, minor, and patch mean
In semantic versioning, you bump major for breaking changes, minor for new backward-compatible features, and patch for backward-compatible bug fixes. The three numbers tell consumers at a glance how risky upgrading to your new version is.
why reset the lower numbers after a bump
Semver requires it: a major bump resets minor and patch to zero, and a minor bump resets patch. Resetting keeps the version sequence meaningful, so 2.0.0 clearly supersedes 1.9.7 rather than leaving a confusing trail of stale numbers.
what if my version has a pre-release tag
This tool focuses on the core major.minor.patch numbers. Pre-release and build metadata, like -beta.1 or +build, follow additional semver rules; handle those separately once you have settled the main version bump.
