May 1, 2026

May 2026 monthly summary for aleph-im/pyaleph. Delivered a critical fix to user authentication token validation by unwrapping configmanager.Item wrappers in require_auth_token, addressing a TypeError and preventing valid tokens from being rejected with 401 errors. Implemented a regression test exercising the Config-based scenario to guard against similar wrapper issues and ensured .value accessors are used before verification. The change improves API reliability on protected endpoints and enhances security posture with correct token handling.

April 2026: Delivered end-to-end enhancements to the credit lifecycle in aleph-im/pyaleph, focusing on expiration enforcement, accurate credit accounting, and improved data retrieval. Key changes include expiration-driven enforcement for credit re-transfers with FIFO-based balance consumption, expiration-aware balance breakdowns, corrected consumed credits for volume resources, and richer filtering, sorting, and pagination for credit history. These efforts reduce expiration bypass risk, improve financial accuracy, and enable more actionable insights for users and operators.

Nov 1, 2024

November 2024 (aleph-im/pyaleph) — Focused API evolution for the Multichain indexer and alignment around its breaking-change ripple. Implemented a visibility-improving rename of the historical data query parameter from 'accurate' to 'completeHistory' to clarify intent and improve retrieval of historical states. This change enhances API semantics and data accuracy for clients while signaling a migration path due to its breaking nature. Complementary fixes were applied to align internal logic with the new parameter, reducing integration risk for downstream services. Result: clearer API semantics, more reliable historical data access, and improved readiness for client migrations.
