Deep Dive
1. Runtime 3800 Upgrade (7 July 2025)
Overview: This was a major runtime upgrade that improved the network's long-term economic policy and interoperability. For users, it means a more predictable token supply and better connectivity with other chains.
The upgrade implemented a new capped linear inflation model, limiting the maximum new GLMR (Moonbeam's token, referenced as a model) to 60 million per year after the total supply reaches 1.2 billion. It expanded bridging capabilities between Moonriver, Moonbeam, and testnets. Technically, it added support for General Message Passing (GMP) and legacy XCM V1, cleaned up lazy migrations, and updated runtime weights for better efficiency. The team noted no changes to the ABI or gas costs, ensuring compatibility for developers.
What this means: This is bullish for MOVR because it creates a more sustainable token economy, which can support long-term value. The improved bridging makes it easier and potentially cheaper to move assets, which could attract more users and developers to the ecosystem.

2. Network Upgrade v0.49.2 (January 2026)
Overview: This was a scheduled network upgrade that required node operators to update their software to maintain sync with the chain. For everyday users, it ensured continued network stability and security.
The upgrade was scheduled for a specific block height (14,629,541). Exchanges like CoinEx suspended deposits and withdrawals temporarily to ensure user asset safety during the transition. Trading on these platforms was unaffected. The upgrade details were referenced in a Moonbeam forum post for version v0.49.2, indicating it included protocol improvements and bug fixes.
What this means: This is neutral for MOVR as it represents essential maintenance. Regular upgrades are crucial for network health and security, preventing outages and vulnerabilities that could harm user experience and trust.

Conclusion
Moonriver's development has focused on core protocol resilience and interoperability, with its last major feature upgrade occurring over a year ago. The subsequent maintenance update highlights ongoing technical stewardship. With the major chain migration to Base now complete, will the next phase of codebase innovation focus on leveraging its new Layer 2 home?
