Status Update - best way to go about?

Hi,

(I'm often adding new material to already published posts or working on a public draft, therefore...) I would like to have a section on my home page that would inform visitors of any recent changes/updates.

Ideally, the section would list the last 5-10 changes made to the site, chronologically. Also, I want to display these updates separately, OUTSIDE of the main post loop.

Here are 3 possible ways I'm considering and I'm hoping to get some guidance from you on which would be the best (or, if there is an option I haven't considered):

Option 1: Sticky Post
The idea is to create one post that would contain all the updates (changelog) on one URL and then Stick it to the front page.
Pros: easy to implement.
Cons: hard to control how much text actually shows on the front page and impossible to socially promote individual updates just by sharing the post.

Option 2: Post format: Status Update
The idea is to use the dedicated post format.
Pros: easy to implement, easy to share on social networks (?)
Cons: don't know how to remove the status updates from the main loop and how to pull them together (the WP Show Posts plugin doesn't seem to allow filtering out by post format).

Option 3: Text Widget
The idea is to type the udpates inside a Text widget.
Pros: Easy to implement and easy control the content
Cons: Needs a new widget area (above the posts) and no history log of updates.

What are your thoughts? Thanks! :)
