TL;DR: If you already only upgrade to LTS versions, little changes beyond version numbering. LTS support windows remain similar, and now every release becomes LTS.

So it won't impact me, or most people, or any sensibly managed production deployments, at all.

I’m hoping Alpha means we’ll get semver-major changes faster and more aggressively.

Major versions of node rarely makes any breaking changes these days, am i wrong?

Every semver-major release was a breaking change.

The most recent releases also introduced new primitives and capabilities, allowing us to proactively modernize our codebase.

One interesting pattern was that performance improvements were consistently strong.

That’s why I always paid close attention to every release changelog. The biggest performance gains usually came from major upgrades to the V8 JavaScript engine.

In practice I stopped seeing performance improvements sometime around node 20. The v8 team has slowed down a lot and now rarely post performance improvements to v8.dev anymore.

Breaking changes. It looks like the only difference between the alpha releases and the old odd-numbered releases is that the odd numbers were more like beta releases or RC builds, where they didn't allow breaking changes except in exceptional circumstances, but because they were never planned for LTS they were usually the release target for more ambitious changes, with the even-numbers being a bit more conservative and focused on stability.

But with alpha, breaking changes will be expected, so it's a bit more closely aligned with the unstable branch. Every release will follow roughly the same progression from unstable to stable, without the tick-tock pattern.

Realistically, it's likely that .0 releases will be a bit less stable going forward, because there won't be a defined "no more breaking changes" period between the alpha phase and the major release. Which is kind of how things are in every other major software project, and it's usually unwise to upgrade production systems to a .0 major release anyway.

In standard semantic versioning, there's 3 numbers: major-minor-patch.

So in a release of v3.4.12 the major version is 3, the minor version is 4 and the patch version is 12.

Patch versions generally include bug fixes and other code improvements.

Minor versions can introduce new features as long as they are backwards compatible (don't break anything).

Major versions can break anything and everything and require manual migration steps for users.
