Biggest opportunity: “acf”, “advanced custom fields” and “google” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

How it's measured →3.3%
of downloads still active
At least 300 of 9.1K lifetime downloads are still running, above its category: the median Booking & Events plugin keeps 0.8%, across 941 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Booking & Events plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
Removal-risk signals
45/100Maintenance 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 3+ years — the top precursor to removal once a vulnerability is found.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| acf your tag | Not in the top 24 | ||
| advanced custom fields your tag | Not in the top 24 | ||
| google your tag | Not in the top 24 | ||
| google calendar your tag | Not in the top 24 | ||

Release cadence

I been using your plug in for 6 years until I had to update to the latest WordPress and php version and then it became incompatible with my web site. Any chance you might come up with and update compatible with WordPress 5.2.2 soon?
