Here's the Versioning Roadmap from the article that announced this project on the TypeScript dev blog.

• https://devblogs.microsoft.com/typescript/typescript-native-port/#versioning-roadmap

Quoted below with added emphasis.

---

Our most recent TypeScript release was TypeScript 5.8, with TypeScript 5.9 coming soon. The JS-based codebase will continue development into the 6.x series, and TypeScript 6.0 will introduce some deprecations and breaking changes to align with the upcoming native codebase.

When the native codebase has reached sufficient parity with the current TypeScript, we’ll be releasing it as TypeScript 7.0. This is still in development and we’ll be announcing stability and feature milestones as they occur.

For the sake of clarity, we’ll refer to them simply as TypeScript 6 (JS) and TypeScript 7 (native)..

While some projects may be able to switch to TypeScript 7 upon release, others may depend on certain API features, legacy configurations, or other constraints that necessitate using TypeScript 6. Recognizing TypeScript’s critical role in the JS development ecosystem, we’ll still be maintaining the JS codebase in the 6.x line until TypeScript 7+ reaches sufficient maturity and adoption.

Our long-term goal is to keep these versions as closely aligned as possible so that you can upgrade to TypeScript 7 as soon as it meets your requirements, or fall back to TypeScript 6 if necessary.
