# Transition To The Community Stack

### The Community Stack

It has always been our goal to provide developers and organizations with great tools, so they can focus on delivering holistic identity solutions. Taking the lessons learned from previous products, we decided to redesign our current offering, resulting in what we now call The Community Stack. A collection of open-source products providing everything to launch any identity solution with ease. You can learn more about it [here](https://walt.id/blog/p/community-stack).

## Transition

Starting from December 2023, the SSI-Kit will halt feature enhancements, leading to a complete discontinuation planned for end-Q3 2024. It's essential to plan your transition to the new stack effectively. \
\
The table below indicates which components of the SSI-Kit are already supported in the new stack.

* For Kotlin/Java projects where SSI-Kit was used as a native dependency, utilize the provided Library for equivalent features in the new stack. •
* If you employed the REST APIs, simply switch to the supplied API in the new stack.

If you have any question, please [reach out](https://walt.id/discord).

All relevant new libaries and APIs have found it's place in the [waltid-identity](https://github.com/walt-id/waltid-identity) repo.
