Sep 1, 2025

September 2025 monthly summary: Focused on enhancing reliability in the Python SDK by correcting the retry configuration in the coinbase/cdp-sdk. The fix ensures the retry strategy is properly applied to network requests, addressing a misconfiguration where max_network_retries was being passed to Configuration. This change reduces transient failures and improves overall system robustness for API calls, with a clear, versioned commit trace.

Nov 1, 2024

Performance-focused month (Nov 2024). Stabilized core SDK surfaces across multiple repos, removed speculative Uniswap pool management from the main branch to reduce risk until full SDK support is ready, and completed coordinated v0.11.0 release work in Python and NodeJS with wallet/funding wallet and staking API enhancements. These changes reduce operational risk, accelerate future liquidity features, and improve developer experience and backend traceability.
