+**Summary:** Groups duplicate import-search results into expandable edition groups, makes running searches cancelable, introduces an adaptive date input with a native picker, detects insecure camera contexts, and fixes timezone handling in the daily page statistics and progress log editing.
 
 **Features**
 - 📚 **Edition groups in the import search**: results from different providers that describe the same book (same ISBN, or same title and authors) are now grouped into expandable entries with an "N results" badge. Compare the variants side by side and import the one you want; no result is dropped anymore. See the [Library guide](/guide/using-librislog/library#how-results-are-grouped) for the exact grouping rules
@@ -48,10 +48,12 @@ LibrisLog v1.8.0 brings camera selection and zoom control to the barcode scanner
 - 📅 **Adaptive date input**: date fields in the book form now use a segmented year/month/day input that no longer assumes the month or day after the first keystroke, validates values as you type, and accepts pasting a complete date. A calendar button next to the field opens the native date picker
 - 🌐 **Searchable timezone picker**: the timezone setting on the profile page is now a searchable dropdown covering all IANA timezones
 - 📷 **Secure context detection in the barcode scanner**: if LibrisLog is served outside a secure context (plain HTTP on a remote host), the scan button is hidden and the scanner explains why the camera cannot start, instead of showing a black box. See the [Library guide](/guide/using-librislog/library#isbn-barcode-scan) for details
+- 🎥 **Active camera name in the scanner**: the barcode scanner now shows the name of the active camera in a badge next to the switch button, so you always know which lens is being used
 - 🔗 **Heimdall dashboard integration**: new documentation for the LibrisLog enhanced app, which shows your reading statistics directly on [Heimdall](https://github.com/linuxserver/Heimdall) tiles
 
 **Bug fixes**
 - 🗓️ **Timezone-correct daily page statistics**: pages read between two progress updates are now attributed to calendar days in the user's timezone instead of fixed 24h slots, so the pages-per-day view matches your local days. Your heatmap may shift slightly after the upgrade
+- 🕐 **Timezone-aware progress date editing**: editing a progress entry's date in the book detail view now interprets the value in your profile timezone instead of the browser's, so entries stay on the correct calendar day and streaks remain accurate
 - 🏷️ **Better contrast for selected suggestion items**: the selected entry in tag and author suggestion dropdowns now has stronger contrast and a visible border in all themes
 
 **Breaking changes:** None.
