Sep 1, 2025September 2025: Delivered cost accuracy, deployment transparency, and security hardening for pyaleph. Key features: historical pricing-based message cost recalculation with auth token utilities and API integration; deployment version display on status page with a dedicated version module and latest-release check. Critical security fix: account permission delegation now enforces proper authorization and raises PermissionDenied to prevent misuse. These changes improve cost predictability, deployment visibility, and system security, strengthening business value for users and operators.

Apr 1, 2025April 2025 monthly summary for aleph-im/pyaleph: Delivered pricing and enforcement enhancements for messaging services. Implemented Messaging Cost Pricing and Balance Enforcement by removing the free tier for storing and processing messages, adding pre-processing balance checks, refactoring the cost calculation logic, and establishing a billing deadline. This work improves cost visibility, enforces responsible usage, and sets the foundation for revenue-aligned messaging features. Work is anchored to commit 32ddc10c3eb1b66d4bb1dfb647d8f083007dd7c2.

Nov 1, 2024November 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.
