v2.5.7 - Banana Pudding 🍌

 Highlights    How to Upgrade    Changelog    Related Releases 

---

We're moving to a beta › latest release pipeline, where all non-hotfix changes are first released in a beta before being promoted to a stable release.

We'd love it if you'd start using the latest betas and let us know early and often if you find any bugs or regressions!

Highlights

This version of ganache-core features the latest and greatest gas exactimation algorithm. While the previous algorithm works well in most cases and was heavily tested, it relied on several assumptions we later found to be incorrect. Gas exactimation 2.0 now makes ZERO assumptions, and returns an exactimation in O(1), compared with O(log n) in geth, parity, etc!

Some notable improvements you might like:

• Completely rewritten without recursion
• Approximately 20% faster and 33% less code
• Works with CREATE2

Stay tuned for a full featured blog post explaining the algorithm and a "Deep Dive" workshop at TruffleCon 2019!
