Rails World 2026 speakers and schedule go live on the website, while core ships critical fixes for markdown rendering and parameter injection in nested attributes.

The Rails World 2026 programme page and speaker talk cards are now live [1], with tab navigation for each day and dynamically linked sessions pulled from schedule.yml to avoid data duplication. This ships alongside small copy corrections to hero banners and sponsor grids [ref:2,5]. On the framework side, ActionText's markdown conversion now correctly flattens block-level content inside links [4], fixing invalid CommonMark output when anchors wrap block elements. A critical fix lands for nested attributes: `RecordNotFound` messages in `ActiveRecord::NestedAttributes#raise_nested_attributes_record_not_found!` no longer interpolate user-controlled IDs directly into error text, closing a parameter injection vector [5]. The collector for unregistered Mime types now emits deprecation warnings instead of silently dispatching stale methods [6], and bind value coercion logic is consolidated to reduce duplication [7]. Across both repos: 16 commits, 11 PRs merged.

Action items

→ Review nested attributes error handling in your app, especially custom validation messages around record lookups rails/rails [plan]
→ Test ActionText markdown output if you render links containing block-level HTML rails/rails [monitor]
→ Check for unregistered Mime type collector warnings in your logs rails/rails [monitor]
