During 2025-07, the Jumpstarter project delivered core enhancements to build reliability, authentication workflows, and installer usability, while addressing critical stability issues and updating documentation. Key features delivered included: - Image build system improvements: enabled rootless builds by adjusting paths and tool usage; updated build scripts to reference proper buildroot/kernel-automotive directories; Dockerfiles bumped to Fedora 42 with new uv.lock dependency. - Automatic OIDC token re-authentication: added automatic re-login on expiry to ensure uninterrupted access to Jumpstarter services. - Jumpstarter installer script and setup UX: new Bash installer with flexible installation sources, custom directories, and clear environment activation/uninstallation instructions. - Exporter logs control in CLI: added --exporter-logs flag to enable exporter logs only when needed, trimming noise. - Exporter logs stability bug fix: fixed AttributeError in exporter logs via correct access to shell_use_profiles in ClientConfigV1Alpha1 and refactored shell launching logic for robustness. - Documentation fix: corrected installation URL to point to the jumpstarter-dev repository. Overall impact: These changes improve build reliability and security, ease the onboarding and installation process, and enhance operator UX by reducing log noise while ensuring robust exporter logging. Business value: more reliable image builds, uninterrupted service access, clearer documentation, and reduced operational overhead. Technologies/skills demonstrated: Docker, Fedora-based image updates, rootless build adoption, Bash scripting for installer, OIDC authentication flows, CLI UX design, error handling and refactoring.

Delivered a new insecure_tls_config flag with integration across client/exporter creation and login flows, accompanied by non-interactive confirmation prompts and comprehensive tests. Strengthened developer experience through DX-driven documentation restructuring, enhanced docs tooling (Sphinx copybutton) and versioned/docs-aware install guidance. Updated installation and packaging instructions to point to the release index and align driver indices with docs, and expanded CAN driver documentation for IsoTpPython/IsoTpSocket configurations. Improved CI/Release workflow posture by removing a legacy wheel publishing action. Fixed a macOS path resolution bug to stabilize tests on /tmp and /private/tmp. Increased timeouts for driver-flashers to improve reliability of serial transfers and login prompts.
