Executive Summary
The GraphOps team is excited to share our updates and achievements this month!
We launched the Subgraph Radio Stable Release 1.0.0 
featuring improved state persistence, enhanced Indexer address validation, updated Slack notification logic, and improved end-to-end tests.
The File Hosting Service repository is now public! This means the community can now track all developments on File Hosting Service —a decentralized, peer-to-peer data sharing platform optimized for efficient and secure file transfers. Our recent efforts focus on enabling file sharing, client-side file discovery, adding a server cost endpoint, and improving server-side local file system methods.
Moving onto Graphcast SDK, we rolled out the version 0.6.0. This release include updated nonce types, reintroduced discovery ENR and refactored the Slack bot for seamless notifications setup.
Within Launchpad, we deprecated Arbitrum Goerli and Graph Goerli namespaces. We also updated Arbitrum namespace, Lighthouse chart and graph-toolbox image build. Additionally, we upgraded various dependencies to bolster reliability. Our team also hosted another Launchpad Office Hours session to recap 2023 progress and outline Launchpad’s roadmap for 2024.
Happy 2024 everyone 
Looking Back (what was delivered)
Subgraph Radio (Documentation, Docker Image, Radio Crate, Radio Source)
- Subgraph Radio Stable Release 1.0.0
- We hosted a live demo and Q&A session on Indexer Office Hours #138
- Upgraded state persistence to use a SQLite database, instead of a JSON file
- Improved Indexer address validation logic
- Removed Waku discovery ENR since it’s now handled by SDK
- Updated Slack notification logic. Slack bot now utilizes webhook.
- Updated e2e tests:
- Added new scenarios
- Improved performance of existing tests (test sender instances are sending messages less frequently, which leads to reduce network load)
