Upcoming Deprecation

The core /speckit.taskstoissues command is planned to move out of Spec Kit core in a future release as GitHub-specific issue tracking transitions to a bundled github-issues extension. The command remains supported for now

The promise a 1.0.0 used to make — and why it stopped mattering

For decades a version number was load-bearing. The 1 in the major slot was insurance, and what it insured against was the cost of change. A breaking change meant a human opening every call site by hand, working through a migration guide line by line, praying the tests caught what the eyes missed. That was expensive, so semver turned the cost into a signal: a bumped major meant budget a bad afternoon — or worse, a frozen major meant build on this without fear. The promise mattered because adapting was the hard part.

That is the assumption that quietly stopped being true. Adjusting to a breaking change is not a bad afternoon anymore — it is a sentence. You point an agent at the diff — the catalog format changed these three fields, update every extension in this repo — and it fixes the call sites in less time than it took me to write this paragraph. Refactoring, the thing we scheduled around and dreaded, got cheap. The migration guide is no longer something you consume; it is something your agent consumes for you.

So the insurance a 1.0.0 sells is insurance against a cost that mostly collapsed. That does not make the number dishonest — it just makes it a number. The old 1.0.0 was a handshake: rely on the shape, I will warn you before I change it. Ours is more of a wave: here is a good place to start; if I move something, your agent will follow it faster than a changelog could describe it. The value moved from stability to adaptability, and adaptability is something you already have.
