In April 2025, the Stellar protocol team delivered a significant scalability enhancement for Soroban via SLP-0003, doubling most ledger-wide limits to address high demand while preserving safeguards for max_tps and ledger_write. The work included a capacity analysis and terminology clarifications, plus documentation updates. Delivery was achieved through three commits: a399b9ad7ca03e758ca88f61717ebb524ef5a194 (SLP003 #1708), 3eafe8577c3cd45915baad2475e8a2cba40d4eba (Update slp-0003 with capacity #1710), and d209df83d6c8196c6663d894ec8e87b56badefed (slp-0003.md fixup #1713). There were no major bugs fixed in this period; the focus was on feature delivery and documentation. Impact: improved throughput capacity, reduced risk of saturation under peak demand, clearer capacity models for planning, and improved developer/operator guidance. Technologies/skills: Soroban protocol, capacity modeling, governance proposal wrapping, documentation, cross-team collaboration, Git-based change management.

February 2025: Delivered performance and documentation improvements for stellar-protocol, focusing on Soroban read throughput and documentation accuracy. Implemented a ledger-wide read byte limit increase to 3.5 MB for Soroban, enabling more WASM data reads and higher throughput per ledger, while aligning with other ledger limits. Completed targeted documentation updates to fix typos in slp-0002.md and bumped CAP versions (CAP-0058 and CAP-0059) in the README. These changes reduce bottlenecks, improve developer experience, and support scalable financial services.

January 2025 monthly summary for stellar/stellar-docs focused on improving documentation clarity around Stellar trustlines. Delivered a feature-level doc update clarifying that trustlines are for holding assets and are not directly tied to trading capabilities; explains that an account can route payments through assets it doesn't hold when acting as a hop in a path payment. Result: improved docs accuracy and reduced potential misinterpretation for developers integrating trustlines. No separate bug fixes recorded for this repo in January 2025.
