What is Gravity Forms?

Gravity Forms Stripe 7.0 restructures how entries and webhooks are handled with Sandbox support

Gravity Forms is in steady maintenance mode: the 3.1.x series delivers merge tag modifiers and security patches, while add-ons (Constant Contact, Signature, HubSpot) receive incremental updates. The exception is Stripe 7.0, which restructures entry/feed/notification handling and adds Stripe Sandbox support for proper test environments alongside automatic webhook configuration. A major version bump from an add-on is unusual and signals architectural rather than cosmetic change.

What is Heroku?

Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.

Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

Gravity Forms vs Heroku: editorial side-by-side

G7.5

Gravity Forms Stripe 7.0 restructures how entries and webhooks are handled with Sandbox support

◆ Current state

Gravity Forms is in steady maintenance mode: the 3.1.x series delivers merge tag modifiers and security patches, while add-ons (Constant Contact, Signature, HubSpot) receive incremental updates. The exception is Stripe 7.0, which restructures entry/feed/notification handling and adds Stripe Sandbox support for proper test environments alongside automatic webhook configuration. A major version bump from an add-on is unusual and signals architectural rather than cosmetic change.

◆ Where it's heading

Gravity Forms is maintaining its position as the WordPress form ecosystem hub by keeping add-ons aligned with provider API evolution—Stripe's architecture shifted, Constant Contact's field model changed, and Gravity Forms tracked both. The product trajectory is maintenance-and-compatibility; the wide add-on surface area is both moat and obligation.

◆ Prediction

Continued add-on version updates tracking upstream API changes; potential AI-assisted form generation features given the broader WordPress ecosystem trend, though no signals are visible yet in this data.

Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.

◆ Current state

Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

◆ Where it's heading

The platform is running two clocks at once. One is a near-daily maintenance cadence that keeps supported runtimes current and rarely changes behaviour. The other is a deliberate, publicly staged lifecycle for the data services, where a major version is walked from beta to GA and the version three releases behind is retired in the same announcement. Kafka is on the same track, with 2.8 and 3.7 deprecations and a revised version-support policy posted in late July.

◆ Prediction

Given that Postgres 15's deprecation was announced alongside 18's general availability, the next concrete step is a published end-of-life date and forced-upgrade window for Postgres 15. The runtime bumps will continue at their current weekly rhythm.
