What each AI video model's release notes say changed

Features often arrive on one tier first

A new feature in a note often comes with a condition: pro mode only, paid plans only, Pro and Mega plans only. Kling 2.1's start and end frames were pro mode only. Midjourney's HD video mode was limited to its top plans in August 2025 and opened to the Standard plan six days later. As of 2026-09-25.

When reading a note, the condition matters as much as the feature. Runway's Seedance 2.0 arrival in April 2026 was limited to Unlimited and Enterprise plans outside the US.
