GravityKit vs runc: at a glance
What is GravityKit?
GravityKit folds every GravityView extension into one Pro plugin.
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.
What is runc?
runc patches one restore bug across four release lines at once.
runc shipped 1.5.3, 1.4.4, 1.3.7 and 1.6.0-rc.2 on the same day, all fixing CVE-2026-119101: a crafted image could make runc restore bind-mount any host directory into a restored container, read-write. Only people who checkpoint and later restore untrusted containers as root are exposed. The 1.6.0 candidate also changes how mount destinations that start with the rootfs path are read, following the runtime spec literally.

GravityKit folds every GravityView extension into one Pro plugin.
◆ Current state
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.
◆ Where it's heading
GravityKit is consolidating a sprawl of separate add-ons into fewer, larger products while steadily adding AI-assistant hooks to individual tools. Paid Featured Tiers suggest the Pro bundle is also a vehicle for listing and directory use cases.
◆ Prediction
Expect the weekly logs to continue with security fixes, and more products to follow GravityView into bundled editions.
runc
5.0INFRA · APIS
runc patches one restore bug across four release lines at once.
◆ Current state
runc shipped 1.5.3, 1.4.4, 1.3.7 and 1.6.0-rc.2 on the same day, all fixing CVE-2026-119101: a crafted image could make runc restore bind-mount any host directory into a restored container, read-write. Only people who checkpoint and later restore untrusted containers as root are exposed. The 1.6.0 candidate also changes how mount destinations that start with the rootfs path are read, following the runtime spec literally.
◆ Where it's heading
The project now maintains four supported branches and backports security work to each one in lockstep, while 1.6.0 keeps trading quiet tolerance for strict spec behaviour: refused read-only configs in rc.1, literal mount paths in rc.2. Users relying on runc's old lenient handling will feel 1.6.0 more than any feature it adds.
◆ Prediction
Expect 1.6.0 final after one more candidate, with 1.3.z ending since 1.3.7 is labelled the probable last patch.
