### Release Notes

<details>
<summary>gitroomhq/postiz-app (gitroomhq/postiz-app)</summary>

### [`v2.14.0`](https://github.com/gitroomhq/postiz-app/releases/tag/v2.14.0): Invite your customers

[Compare Source](https://github.com/gitroomhq/postiz-app/compare/v2.13.0...v2.14.0)

This is a major, stressful release, and part of a bigger thing in the future.
Adding an account to Postiz does not require you to be logged in.

That means if you have an "add account link" (a new button), you can send it to your customers to add their accounts (Currently supported for OAuth2 - only account)

This is a big part of creating the multi-tendency option in the future.

Aside from that, we also added:

- Character counter to the global mode shows the total chars and the social media with the smallest amount of chars.
- List mode of posts
