I'm fine with the formatting changes, but I'm not sure that the timelines are accurate based on PyPI release history. Can you verify with @thomas-te @cicdw and @aaazzam on these?

Prefect 1.0 was released in 2022 based on the PyPI release history. https://pypi.org/project/prefect/1.0.0/

Suggested change

	**2018-2021:** Our story begins with Prefect 1.0, in which we introduced the idea that workflow orchestration should be Pythonic.

Yea this is a question of narrative accuracy vs. technical precision: you are right that 1.0 was released in 2022, but it was basically a stamp on the culmination of 0.x work since 2018.

I think for the purposes of this timeline we're trying to emphasize Prefect's innovation not the specific release, so I personally vote to remove the 1.0 precision and simply say "Our story begins in 2018, when we introduced the idea that workflow orchestration should be Pythonic."

Prefect 2.0 was also released in 2022. https://pypi.org/project/prefect/2.0.0/

Suggested change

	**2022-2024:** Prefect's 2.0 release became inevitable once we recognized that real-world workflows don't always fit into neat, pre-planned DAG structures: sometimes you need to update a job definition based on runtime information, for example by skipping a branch of your workflow.

Sorry, I got the 3.0 release date wrong in my earlier comment, but I think the suggestions still stand.

[daniel-prefect]

Even though the release year for 3.0 is accurate, I wonder if we should say 2023-present to avoid any gaps with the previous entry in the timeline.

Suggested change

	**2024 and beyond:** With our release of Prefect 3.0 in 2024, we fully embraced these dynamic patterns by open-sourcing our events and automations backend, allowing users to natively represent event-driven workflows and gain additional observability into their execution.
