| 8 | +# A Sneak Peek into the Pact Python Future |
| 9 | + |
| 10 | +We are thrilled to announce the release of [Pact Python `v2.2`](https://github.com/pact-foundation/pact-python/releases/tag/v2.2.0), a significant milestone that not only improves upon the existing features but also offers an exclusive preview into the future of contract testing with Python. |
| 11 | + |
| 12 | +## A Glimpse Ahead with [`pact.v3`][pact.v3] |
| 13 | + |
| 14 | +The work is taking shape in a branch-new module – [`pact.v3`][pact.v3] – that serves as an early preview of what will become Pact Python `v3`. This will provide full support for Pact Specifications `v3` and `v4`. |
| 15 | + |
| 16 | +This new version harnesses the power of Rust's foreign function interface (FFI) library, promising enhanced performance and reliability. It will also make it easier to incorporate upstream changes in the future. Although it's just a sneak peek, it's an open invitation for you to explore what's coming and contribute to shaping its final form. |

| 30 | +## The Roadmap Ahead |
| 31 | + |
| 32 | +Transitioning to a new version can be daunting; thus, we've planned a staged migration: |
| 33 | + |
| 34 | +### :construction: Stage 1 (from v2.2) |
| 35 | + |
| 36 | +- The existing library remains operational with continued support for minor updates. |
| 37 | +- The new `pact.v3` is available for trial but should be used cautiously as changes are expected. |
| 38 | +- It's not recommended for production use yet, but feedback from experimentation is encouraged. |
| 39 | +- Expect [`PendingDeprecationWarning`](https://docs.python.org/3/library/exceptions.html#PendingDeprecationWarning) alerts when using the current library. |
| 40 | + |
| 41 | +### :hammer_and_wrench: Stage 2 (from v2.3, to be confirmed) |
| 42 | + |
| 43 | +- The `pact.v3` module is anticipated to stabilize and we urge users to start planning their migration. |
| 44 | +- Comprehensive migration guidance will be provided for a seamless transition. |
| 45 | +- More assertive [`DeprecationWarning`](https://docs.python.org/3/library/exceptions.html#DeprecationWarning) notifications will prompt users to switch to the new module. |
| 46 | +- This phase will provide ample time, likely spanning a few months, for users to adapt. |
| 47 | + |
| 48 | +### :rocket: Stage 3 (from v3) |
| 49 | + |
| 50 | +- The `pact.v3` module graduates to simply `pact`, signaling its readiness as the primary library. |
| 51 | + - Migrators from `pact.v3` can expect minimal effort adjustments – mostly a find-and-replace task from `pact.v3` to `pact`. |
| 52 | + - Any necessary breaking changes identified during Stage 2 will be implemented, with detailed guidance provided. |
| 53 | +- The original library moves under the `pact.v2` umbrella. |
| 54 | + - This significant shift means that code written for Pact Python v2 will require attention to function with `v3`. |
| 55 | + - Users loyal to `v2` must update their imports to accommodate the new `pact.v2` scope. |
| 56 | + - With its move, `pact.v2` steps into the sunset of its lifecycle, focusing on critical fixes until its eventual retirement. |
| 57 | + |
| 58 | +## Embrace the Evolution |
