Flux: No action is required from users using Flux.
Services providers
The latest Full Node v2.0.0 and Explorer Backend 1.13.1 (if necessary) must be installed for service providers such as exchanges and wallet providers. The ones running dockers must use the latest docker image with the matched version of the full node and explorer backend.

Leman Network Upgrade Enhancements
Security
The Leman Network Upgrade includes new features at the language (Ralph) and Virtual Machine (Alphred) level, which will aid developers in creating complex dApps more easily.
Bridge
The Leman Upgrade clears the way for Alephium Bridge deployment, connecting Alephium and other blockchains. It will enable seamless interaction and interoperability between our ecosystem and other blockchains, starting with Ethereum.
Developer Experience & SDK
The Leman Upgrade has new Virtual Machine instructions and built-in functions. The “Sub-contract” concept and new built-in functions for debugging, asserting, logging, migrating existing contracts, burning tokens, etc., to improve the dApp development experience.
New Node/Explorer APIs, web3 library, and wallets (through WalletConnect & browser extension) will help reduce the required software development cycle to build dApps on Alephium.
