What is Blue?

Blue's feed is capturing a Cloudflare timeout page instead of a changelog

There is no product content here. Both captured rows are fragments of a Cloudflare error interstitial — a 'What happened?' block reporting that the connection between Cloudflare's network and the origin web server timed out, and a 'What can I do?' block advising a retry. Neither has a date or a source URL. The crawl reached the CDN and never reached Blue.

What is Sugar Calendar?

Events can finally ask attendees a question at the moment they sign up.

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

Blue vs Sugar Calendar: editorial side-by-side

B0.0

Blue's feed is capturing a Cloudflare timeout page instead of a changelog

◆ Current state

There is no product content here. Both captured rows are fragments of a Cloudflare error interstitial — a 'What happened?' block reporting that the connection between Cloudflare's network and the origin web server timed out, and a 'What can I do?' block advising a retry. Neither has a date or a source URL. The crawl reached the CDN and never reached Blue.

◆ Where it's heading

Nothing about the product can be read from an error page. The only conclusion supported is operational: whatever URL is configured for this product was returning a 522-class timeout at capture time, so either the origin was down or the configured endpoint is wrong.

◆ Prediction

Unclear, and not answerable until the source is fixed. The next crawl will either return real entries if the origin recovers, or the same interstitial if the endpoint itself is misconfigured.

S5.0

Events can finally ask attendees a question at the moment they sign up.

◆ Current state

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

◆ Where it's heading

Every release this quarter has removed one thing an organiser previously did outside the plugin — the follow-up email, the page builder, the pricing spreadsheet, the Zoom link, and now the post-signup questionnaire and the spreadsheet of answers that went stale on the first cancellation. The pattern is consistent enough to read as a deliberate sweep of the manual work around an event rather than a feature roadmap. Each arrives as a how-to titled post rather than a release note.

◆ Prediction

Answers now sit on the attendee record, so the next obvious step is doing something with them in bulk — filtering or exporting attendees by response, or segmenting the follow-up email by answer. The post stops at collection.
