Scheduled

We are proceeding with an urgent upgrade of our NEAR Testnet nodes to version 2.7.0-rc.2 on 2025-07-01 at 11:30 UTC (revised from previously scheduled v2.7.0-rc.1).

This release addresses a critical compatibility issue introduced in v2.7.0-rc.1, which broke backward access to state changes involving the BandwidthSchedulerStateUpdate enum. It also resolves a CPU performance regression affecting nodes that sync from scratch using epoch sync.

No protocol upgrade, database change, or security patch is involved. This is a non-breaking but mandatory hotfix for Testnet stability.



📦 Key changes in this release include:
• Fix: Restores missing StateChangeCause enum variant to preserve compatibility with historical queries
• Fix: Reduces CPU overhead during header sync for freshly started nodes
• No protocol or DB upgrade required
