The short version

What changed, and why it matters

This commit updates the Rust zeroize library from version 1.8.1 to 1.8.2 in a cryptocurrency hardware wallet firmware project. The zeroize library is used to securely erase sensitive data like private keys from memory after use. The commit also adds a large Chinese-language technical specification document for Sui blockchain support. The actual code change is a routine dependency patch with no direct exploit visible in the diff, but the commit message claims it is for 'improved security features.'

Recommended action

Verify the zeroize 1.8.2 changelog for any security fixes relevant to the project's usage, confirm the exact-version pin is intentional and does not block future patches, and review whether the Sui signing code actually follows the documented zeroize practices.
