 All notable changes to this project will be documented in this file.

+## 2.8.7 - 2026-08-22
+
+### Added
+
+- Added configurable JSON POST requests and two-step login-then-token authentication for API sources.
+
+## 2.8.6 - 2026-08-18
+
+### Fixed
+
+- Added live URL validation with inline feedback and explicit HTTP or HTTPS scheme enforcement for URL fields.
+- Prevented Enter in slide editor inputs from implicitly saving the slide.
+- Collapsed nested API response JSON sections by default while keeping the root response visible.
+
+## 2.8.5 - 2026-08-17
+
+### Fixed
+
+- Fixed thumbnail capture timing so video assets are ready before the preview canvas is captured.
+- Replaced unavailable webpage thumbnails with a subdued placeholder while keeping live webpage previews intact.
+
+## 2.8.4 - 2026-08-17
+
+### Added
+
+- Added local caching for API and RSS image placeholders under `player-cache/remote-images` for offline player playback.
+- Added reconciliation of cached remote images so files no longer referenced by slides are removed.
+
+### Fixed
+
+- Fixed popup preview authentication for background thumbnail capture.
+- Fixed thumbnails so they use the same popup-preview canvas and resolve API/RSS placeholders, fonts, styles, and cached images correctly.
+- Fixed manual scheduled-task run notifications so they use task-neutral wording.
+
+## 2.8.3 - 2026-08-17
+
+### Added
+
+- Added API, RSS, Timetable, and Time / Date placeholder help panels with shared transform and date-token documentation.
+- Added render-time API and RSS image placeholders with proportional sizing and preview-only bounding boxes.
+
+### Changed
+
+- API and RSS regions now preserve authored content when no data source is selected and remain blank when a selected source has no authored content.
+- Normal WYSIWYG image insertion remains upload-backed and separate from image placeholder transforms.
+
 ## 2.8.2 - 2026-08-16
