Sulu
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
A side-by-side editorial comparison of WPForms and Buttondown — release velocity, themes, recent moves, and the top alternatives to consider.
WPForms fills its feed with tutorials while signposting a v2.0 it has not shipped here.
WPForms publishes on a near-daily tutorial cadence, and the entire visible window is instructional: connecting forms to Make.com and Slack, assembling an applicant tracker out of forms and entries, and separating confirmations from notifications. A retrospective post frames the recent stretch of releases as the road to WPForms v2.0, but the feed carries no release notes for it. What is visible is documentation of existing capability, not new capability.
Buttondown ships something almost every day, and most of it is somebody's bug report.
Buttondown publishes a dated entry nearly every day, and the mix is dominated by small fixes credited to named users. The feature work in this window is narrow but real: filtered blocks for audience-specific email sections, Mermaid diagram rendering, and enhanced Bluesky link cards. Nothing here changes the product's shape.

The through-line across the tutorials is integration and routing — getting submissions out of WordPress and into the tools where work actually happens. Stacked with the v2.0 retrospective's claim that AI features have been accumulating quietly, the product is being positioned as a data-capture front end for other systems rather than a forms builder alone. The conversion-benchmarks post points the same way, toward measurement of what forms produce.
Given the v2.0 framing and the run of integration tutorials, the next substantive post is likely a v2.0 feature tour or another native integration walkthrough. The feed does not carry release notes, so any actual shipping detail will have to come from elsewhere.

Nothing here changes the product's shape.
The cadence is the strategy - a steady stream of small corrections keeps the surface tidy rather than betting on a large release. Recent additions cluster around how a publication looks off-platform: Bluesky cards, archive fonts, recognized social links, image handling. Segmentation is the one direction with real room to grow, and filtered blocks is its first visible step.
Filtered blocks is the piece most likely to expand, since per-audience content inside a single send invites conditional logic beyond one block type. The daily fix cadence should continue at its current rate.
