What is GravityKit?

GravityKit makes Gravity Forms merge tags readable chips you can preview before saving.

GravityKit ships a weekly Launch Log across its Gravity Forms add-ons. Early October brought Visual Merge Tags in Foundation 1.35.0, turning raw merge tags into editable chips previewed against real entries. Later weeks added AI-built boards, AI-managed calendars, a range-slider search, live DataTables totals and a steady stream of security fixes across the suite.

What is Transmission?

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

GravityKit makes Gravity Forms merge tags readable chips you can preview before saving.

◆ Current state

GravityKit ships a weekly Launch Log across its Gravity Forms add-ons. Early October brought Visual Merge Tags in Foundation 1.35.0, turning raw merge tags into editable chips previewed against real entries. Later weeks added AI-built boards, AI-managed calendars, a range-slider search, live DataTables totals and a steady stream of security fixes across the suite.

◆ Where it's heading

The suite is moving in two directions at once: making Gravity Forms configuration less cryptic for site builders, and letting AI assistants operate its products through MCP. Security fixes appear in most weekly logs, a sign of a large plugin surface under active review.

◆ Prediction

Expect more GravityKit products to gain AI-assistant control and weekly security patches; whether Visual Merge Tags spreads to other plugins' settings is unclear.

0.0

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

◆ Current state

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

◆ Where it's heading

The interesting work is at the integration boundary, not in the download engine: the RPC surface has been standardised and renamed, and beta.5 was largely spent repairing what those changes broke, including backwards-incompatible keys accidentally written into settings files. That is the cost profile of an API migration in a project with a large ecosystem of third-party remotes. With feature freeze held for seven months and no 4.1.0 final, the release is late relative to its own stated plan.

◆ Prediction

The next release should be 4.1.0 final or a further beta rather than new features, since the branch is frozen — but the entries give no signal on what is holding it.
