ChatPromptBuilder is not available in 2.2.1 despite it being in the 2.2 documentation

Hi everyone,

I've encountered an issue with the ChatPromptBuilder class. According to the documentation for version 2.2, this class should be available. However, when I try to use it with version 2.2.1, it appears to be missing.

This is particularly concerning as the DynamicChatPromptBuilder, which I understand ChatPromptBuilder is intended to replace, is marked as deprecated in the upcoming 2.4 release. The absence of ChatPromptBuilder leaves no clear upgrade path.

Can you provide any insights on whether ChatPromptBuilder was omitted from the 2.2.1 release by mistake? If so, will it be added in a future patch, or should we anticipate its availability only in version 2.4?

Thank you for your assistance!

Hey! See #7794.

The ChatPromptBuilder is available, but we forgot to export it.

In the meantime, you can import the component as follows:
from haystack.components.builders.chat_prompt_builder import ChatPromptBuilder
