Sep 1, 2025

September 2025 focused on extending Stellar token support in trezor-suite. Key changes include Stellar token-aware transaction parsing and UI enhancements to clearly display token transfers (token name, symbol, amount) within transaction details, and a fix to render translation strings within the UI. In addition, updated outdated account detection to consider Stellar token balance changes, ensuring the account state reflects token activity. These improvements reduce user confusion, improve balance accuracy, and strengthen Stellar token handling from parsing to presentation.
