Deep Dive
1. Core Node v1.2.0 & Mainnet Hard Fork (October 2025)
Overview: This was a mandatory upgrade for all node operators, requiring them to update to version 1.2.0 to remain compatible with the network. It prepared for a scheduled mainnet hard fork and introduced backend improvements.
The release included order handling improvements, security upgrades, and updates to the API server and wallet for atomic swap order flow. A mainnet hard fork was scheduled to follow this release, ensuring the network could implement these new features and fixes.
What this means: This is neutral for CORE as it represents essential maintenance. It makes the network more secure and efficient for developers building on it, which is a foundational requirement for long-term growth. The mandatory update ensures all participants are on the same page, reducing the risk of network splits or instability.
