June 2025 — Brave Core delivered four major feature/bug-fix efforts focused on reliability, data integrity, and media processing. Key outcomes include safer database migrations with corrected test data dumps, expanded testing for PrintPreviewExtractor, a robust PDF text extraction workflow, and a validated YouTube transcript workflow via InnerTube API. These efforts reduce migration risk, improve test resiliency, enhance end-user feature stability, and strengthen performance and data handling across media-related components.

May 2025 highlights for brave/brave-core: two high-impact features delivered to improve print reliability and AI-assisted content capture. Expanded print preview host allow-list to include watermark.silverchair.com, enabling consistent print output for additional publishers. Added full PDF content extraction in AI Chat with print preview integration, improving content fidelity and error handling across extraction methods. These changes reduce manual steps, broaden content access, and strengthen robustness of core workflows.

April 2025: Delivered AI Chat full-page screenshot capture and paint preview integration in brave-core, enabling multi-shot composition and making screenshots available to the AI Chat feature for improved understanding of web content. The work is captured in commit e7538132277ab34b8d8d0240c71b89aa85e95ffb (PR #28714). No major bugs reported in Brave Core related to this area this month.

March 2025 monthly summary for brave/brave-core focusing on user-facing AI features and reliability improvements. Delivered initial AI Chat image attachment support with a UI for file selection and preview, plus backend readiness for image data handling and vision-model processing. Established groundwork for multi-image uploads per conversation (up to 64 images) and prepared default vision-model behavior for freemium and premium tiers. Fixed Windows Print Preview failures by replacing hardcoded JSON values with dynamically generated print settings and ensuring the printer type is set to kPdf to align with upstream Chromium enum changes. Result: enhanced user engagement with image-enabled AI conversations, improved release stability, and a scalable path for media-rich features.

January 2025 — Brave Core: Focused on stabilizing CI reliability on macOS ARM64 by disabling a flaky test, aligning with issue #27110. The change prevents CI timeouts and flakiness, improving feedback loops for PRs and overall build stability.
