d8ea041c56 docs: introduce versioned docs and migrate to fuma (#11166)
## Todos for release

- [x] Configure Env in docs project on vercel
- [x] Configure Root Path in the docs project on vercel
- [ ] Remove old CSP https://github.com/zitadel/website/pull/1592

## What we did

This pull request migrates the project documentation from the old
`docs/` directory to the new `apps/docs/` directory, introduces a new
documentation system built with Next.js and Fumadocs, and updates all
relevant references, configuration files, and documentation to reflect
this change. It also adds new configuration and ignore files for the new
documentation app, updates CI and linting to exclude the new docs from
certain checks, and revises the contributing guidelines accordingly.

**Documentation System Migration and New Docs App**

* Migrated all documentation from `docs/` to `apps/docs/`, and updated
all references in `README.md`, `CONTRIBUTING.md`, and other files to
point to the new location.

and a comprehensive `README.md` with development and contribution
instructions.

**Configuration and Tooling Updates**

* Updated `.github/workflows/codeql.yml`, `.golangci.yaml`, and
`.github/dependabot.yml` to properly handle the new docs app: excluded
`apps/docs` from certain checks, added npm dependency updates for the
docs app, and excluded generated content.

* Updated `.devcontainer/devcontainer.json` to use the latest Go 1.25.3
version for consistency.

**Licensing and Miscellaneous**

* Added `apps/docs/` to the list of licensed directories in
`LICENSING.md`.

These changes ensure the documentation is now maintained in a modern,
scalable system and all project tooling is updated to support the new
structure.

title: Technical Advisory 10004
---
## Date and Version
Version: 2.39.0
Date: 2023-10-14
## Description
Due to storage optimizations ZITADEL changes the behavior of sequences.
This change improves command (create, update, delete) performance of ZITADEL.
Sequences are no longer unique inside an instance.
From now on sequences are upcounting per aggregate id.
For example sequences of newly created users begin at 1.
Existing sequences remain untouched.
## Statement
This change is tracked in the following PR: [new eventstore framework](https://github.com/zitadel/zitadel/issues/5358).
As soon as the release version is published, we will include the version here.
## Mitigation
If you use the ListEvents API to scrape events use the creation date instead of the sequence.
If you use sequences on a list of objects it's no longer guaranteed to have unique sequences across the list.
Therefore it's recommended to use the change data of the objects instead.
## Impact
Once this update has been released and deployed, sequences are no longer unique inside an instance.
ZITADEL will increase parallel write capabilities, because there is no global sequence to track anymore.
Editor service does not respond the different services of ZITADEL anymore, it returns zitadel.
As we are switching to resource based API's there is no need for this field anymore.
