High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 15+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 3.2.1, well behind 6.8.

Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

Thank you! I was trying to hack the wordpress sidebar calendar to achieve ajax ‘next’ and ‘prev’ buttons and exclude or include certain categories of my posts. What it would be very nice is to use it on custom post types. Thankyou very much indeed!

Just what I was looking for to help the navigation of my blog site with hundreds of posts from over the years. Works like a charm.

I would not recommend this Calendar unless you are well versed at coding. I am a new at this, so maybe for those who does this everyday I may be wrong.
