September 2025: Delivered critical platform improvements and migration-focused cleanup across publisher and rsconnect repos. In posit-dev/publisher, implemented Connect Cloud enhancements including ContentRequestBase serialization tweaks, new runtime settings support, and hardened access control, culminating in the 1.20.0 release. Also added an auto-restart feature for the agent to improve resilience, and completed maintenance/documentation updates (version 1.19.1) to clarify troubleshooting and release notes. In rstudio/rsconnect, deprecated Posit Cloud functionality, cleaned up cloud-specific code, tests, and docs to focus on shinyapps.io, and reintroduced the Shinyapps.io bundle upload flow, with deployment integrity checks to ensure full deployments to Posit Connect.

Aug 1, 2025

August 2025 monthly summary for posit-dev/publisher focusing on Connect Cloud publishing improvements, credentials resilience, observability, and deployment UX. Key features delivered include a dedicated Connect Cloud publishing workflow with a clear separation of concerns (decoupling generic publishing from Connect-specific code) and robust API client support. Password/credential handling was hardened with automatic refresh workflows and an explicit environment field for cloud credentials, plus a default product type is now applied when loading config/deployments to prevent misconfigurations. Observability and reliability were significantly improved by fetching logs during the publishing flow, updating agent-emitted events for Connect Cloud publishing, and exposing runtime logs after publish to aid troubleshooting. The publishing schema was evolved to include product_type and Connect Cloud properties, enabling richer metadata and easier governance. Deployment orchestration and UX were enhanced with improved NextRevision/RevisionOverrides handling and better validation/error messaging, alongside Connect Cloud UX improvements (secrets, access control, vanity names, and error messaging), and reliability improvements for e2e runs (installing the extension on every run) plus documentation updates for Connect Cloud workflows.
