December 2024 monthly performance highlights across recallnet/ipc and recallnet/rust-recall. Key features delivered center on metadata management, pricing and cost-model alignment, and cross-repo API hygiene that improves reliability, cost predictability, and developer productivity. In ipc, object metadata management was implemented and refined via a dedicated ModifyObjectMetadata API, later renamed to UpdateObjectMetadata with pre-state validation, while moving size-limit constants to a shared module to ensure consistent validation before state updates. The credit system was standardized and aligned with gas-based pricing by renaming terms to gas allowances, integrating gas-fee limits into approvals, and introducing a TokenCreditRate type to support attos-based conversions. In rust-recall, the credit pricing and rate management overhaul modernized storage-cost handling, including renamed fields for credit limits and gas fees and the addition of a flexible token credit rate representation. A bucket metadata CLI feature was added to recall, with corresponding SDK/provider updates to support optional values and enforce size constraints. Overall, these changes improve cost accuracy, pricing transparency, and system-wide consistency, enabling faster feature delivery and more reliable operations.
