⬆️ Install or Upgrade

Follow the Flow CLI installation guide for instructions on how to install or upgrade the CLI.

⭐ Features

Inline Fork Testing with #test_fork Pragma

The Cadence Test Framework now supports the #test_fork pragma, enabling inline fork testing directly in your test files. Fork a network snapshot for individual test functions without needing separate CLI flags.

Example:

// Test swapping on IncrementFi by forking mainnet
#test_fork(mainnet)
access(all) fun testIncrementFiSwap() {
    // ... test swap logic with live contract dependencies
}

The DeFi Actions scaffold (flow init) includes a ready-to-use IncrementFi fork test example showcasing this new capability.

Full Scheduled Transaction Support

The Flow Emulator and Cadence Test Framework now support scheduled transactions, including all the latest scheduled callback features live (or coming soon) on mainnet. Test time-based logic and deferred execution end-to-end in your local environment.

🛠 Improvements

Execution Effort Recalibration (FLIP 346)

The Flow Emulator and Test Framework now support the updated execution effort weights from FLIP 346, which recalibrates transaction metering to better align with actual computational costs. This delivers fairer pricing and stronger network stability.

Key improvements:

  • Flow token transfer: 27 → 19 computation (30% reduction)
  • NFT transfer: 48 → 26 computation (46% reduction)
  • EVM token transfer: 143 → 28 computation (80% reduction)
  • EVM gas capacity: 50M → 220M gas per transaction
  • 99.995% of existing transactions remain compatible

This change improves fee fairness, reduces costs for common operations, and strengthens network resilience against resource exhaustion attacks.

Compute Limit Terminology

Updated terminology from "gas limit" to "compute limit" to better reflect Flow's resource metering model. This change affects CLI output and messaging, aligning with FLIP 346's execution effort recalibration.

Fork Testing Metrics

Added instrumentation and metrics for fork testing operations to help track performance and reliability of forked test sessions.
