Release Notes
Here is copied messages from cosmos-sdk repository for security updates.
"""
Recently, the Cosmos-SDK team became aware of a high-severity security vulnerability that impacts Cosmos-SDK v0.43.x and v0.44.x and can result in a consensus halt. User funds are NOT at risk; however, the vulnerability can result in a chain halt. This vulnerability does not impact the current Cosmos Hub, though other Cosmos-SDK based blockchains using v0.43.x or v0.44.x may be affected and are advised to update to v0.44.2 immediately.
Nodes can update their software independently of each other (no coordinated chain restart necessary), but should do so as soon as they are able.
A full disclosure will be published a week after the release.
