September 2025 monthly summary for lidofinance/lido-oracle: Key reliability, performance, and build hygiene improvements. Implemented Lido as a new IPFS provider with concurrent publishing, enhanced IPFS checks, and added unit tests. Refined the IPFS publish workflow (e.g., removing frame numbers, reducing default timeouts) to improve reliability and speed. Strengthened deployment reproducibility by pinning dependencies, removing unused licenses during builds, and standardizing Dockerfile/parser versions, complemented by a curl upgrade. These changes delivered measurable business value: more reliable IPFS publishing across providers, faster CI/CD, and lower production risk.
