Urgent Fluent - Testnet - Upgrade to v1.5.0

Scheduled for Sep 17, 14:00 UTC - Sep 18, 00:00 UTC

Scheduled

We are upgrading our Fluent Testnet infrastructure to v1.5.0 (ALKAHEST) on 2026-09-17. This release focuses on runtime stability, EVM correctness, and performance improvements, including fixes for node crashes, bridge-related block failures, malformed-input handling, gas accounting, Solidity ABI compatibility, and contract routing. It also upgrades rWasm to version 0.6.0 and reduces execution overhead. Brief interruptions to RPC availability may occur on that date.
