 All notable changes to this project will be documented in this file.
 
-## [Unreleased]
+## [v6.2.2] - 2024-01-10
 
+- Hotfix for a bug in request pipelining.
+
+## [v6.2.0] - 2024-01-09
+
+- Nextcloud 28 compatibility
+- Various bug fixes
+
+## [v6.1.5] - 2023-11-25
+
+- Hotfix in service worker caching strategy.
+
+## [v6.1.1] - 2023-11-24
+
+- This is an off-cycle hotfix release for some bugs in v6.1.0 ([see](https://github.com/pulsejet/memories/milestone/19?closed=1)).
+- **Breaking**: The CUDA scaler is now the default for NVENC. You may need to reconfigure your transcoder. (see [#582](https://github.com/pulsejet/memories/issues/582))
+- This release also cuts down a lot of weirdness and improves the usage of dependencies significantly.
+
+## [v6.1.0] - 2023-11-15
+
+- **Feature**: RAW files are now hidden (stacked) when another file with the same basename exists ([#537](https://github.com/pulsejet/memories/issues/537), [#152](https://github.com/pulsejet/memories/issues/152), [#419](https://github.com/pulsejet/memories/issues/419))
+- **Feature**: Multiple files can be now selected and shared from the timeline ([#472](https://github.com/pulsejet/memories/issues/472), [#901](https://github.com/pulsejet/memories/issues/901))
+- **Feature**: Bulk rotating of images. You can now rotate images losslessly by editing the rotation EXIF metadata. ([#856](https://github.com/pulsejet/memories/issues/856))
+- **Feature**: Icon animation when playing live photos ([#898](https://github.com/pulsejet/memories/issues/898))
+- **Feature**: Swipe to refresh on timeline ([#547](https://github.com/pulsejet/memories/issues/547))
+- **Bugfix**: Allow switching video to direct on Safari ([#650](https://github.com/pulsejet/memories/issues/650))
+- Many other [bug fixes](https://github.com/pulsejet/memories/milestone/18?closed=1)

+
+## [v6.0.1] - 2023-10-27
+
+- Bug fixes in video streaming.
+
+## [v6.0.0] - 2023-10-25
+
+- This release focuses on improvements in code quality, maintainability and [documentation](https://memories.gallery/install/).
+    - New CI/CD [jobs](https://github.com/pulsejet/memories/actions/workflows/static-analysis.yaml) for type checking with [Psalm](https://psalm.dev/) and [vue-tsc](https://www.npmjs.com/package/vue-tsc)
+    - Vue templates are now checked and largely type-safe
+    - The backend now has native type coverage with PHP 8 type hints. This unearthed multiple bugs that are now fixed.
+    - [Developing](https://github.com/pulsejet/memories/#-development-setup) is now easier for new contributors
+- **Breaking**: Nextcloud 26+ and PHP 8.0 are now required.
+- **Breaking**: The directory containing the `exiftool` and `go-vod` binaries was renamed from `exiftool-bin` to `bin-ext`
+- **Feature**: External transcoders are much easier to set up now. See [docs](https://memories.gallery/hw-transcoding) for details.
+- **Feature**: Folders view in shares ([#880](https://github.com/pulsejet/memories/pull/880))
+- **Feature**: Improved back button navigation on mobile ([#861](https://github.com/pulsejet/memories/issues/861)).
+- **Feature**: The transcoding quality factor can now be configured from the admin panel.
+
+## [v5.5.0] - 2023-10-06
+
+- **Important**: This update runs some slow database migrations. It is recommended to upgrade using the CLI (`occ upgrade`) instead of the web interface.
+- **Important**: This version corrects some errors in indexing and indexes some new EXIF fields. It is recommended to run `occ memories:index -f` after upgrading.
 - **Breaking**: Files in hidden folders are now hidden in the timeline ([#825](https://github.com/pulsejet/memories/issues/825))
+- **Feature**: An Android app is now available with early access (https://play.google.com/store/apps/details?id=gallery.memories). Memories v5.5+ is required.
 - **Feature**: Support showing full file path in sidebar ([#173](https://github.com/pulsejet/memories/issues/173))
 - **Feature**: View file in folder on clicking name in sidebar
 - **Feature**: User can leave albums that are shared with them

-## Storage support
+## Recommended Apps
 
-The app can work with external storage for photos. Just set the mountpoint as the timeline directory.
+For the best experience and performance, the following apps are recommended.
 
-- If you add any photos from outside Nextcloud, you must run the scan and index commands.
-- Indexing may be slow, since all files must be downloaded from the storage.
+- [Preview Generator](https://github.com/nextcloud/previewgenerator) - For pre-generating image previews (**required** for performance)
+- [Recognize](https://github.com/nextcloud/recognize) - The official Nextcloud app for AI tagging of images and people.
+- [Photos](https://github.com/nextcloud/photos) - The official Nextcloud Photos app, required for albums support.
+- [Face Recognition](https://github.com/matiasdelellis/facerecognition) - An alternative face recognition app, which offers more fine-tuning. Alpha stage integration.
+
+## Storage Support
+
+Memories works out-of-the-box with most Nextcloud setups, including with external storage.
+
+- If you upload any photos from outside of Nextcloud, you may need to run the `occ files:scan` and `occ memories:index` commands.
+- With external storage, indexing may be slow since all files must be downloaded.
 
 !!! warning "Transcoding with external storage"
 
     Video transcoding requires the entire file to be available locally for ffmpeg. To prevent downloading the
     entire for every playback, transcoding is disabled for external storage.
 
-## Image/Video support
-
-To get support for all file types including HEIC, TIFF and RAW, refer to [this page](./file-types.md).
-
-To enable support for high resolution images, you need to update Nextcloud's `config.php` to include
-
-```php
-'preview_max_memory' => 4096,
-'preview_max_filesize_image' => 256,
-```
-
 ## Transcoding
 
-Memories bundles a [transcoding server](https://github.com/pulsejet/go-vod) with HLS capabilites for adaptive streaming. You need to configure transcoding to be able to play any videos. HLS enables the browser to download the video as small chunks and in resolutions adaptive to the connection speed. As a result, this is usually expected to have a major boost in video experience and performance.

-## Reverse geocoding
+!!! tip "Hardware Acceleration"
 
-Memories supports reverse geocoding to find the location of photos. To set up geocoding you need to download the planet boundary dataset and store it in the database. This works only on MySQL/MariaDB/Postgres (no SQLite support). To set up, go to the admin panel. Note that all your files will be re-indexed after downloading the planet database.
+    Memories supports hardware acceleration for transcoding using VA-API and NVENC.
+    If you have compatible hardware, using acceleration can significantly improve performance.

+
+    Reverse geocoding and the map of photos are **two separate features** and do not depend on each other.
+
+## Preview Storage
 
 By default, previews upto `4096px` size are generated by Nextcloud. Each of the largest previews might be a few megabytes in size. This may not be ideal if you have limited storage space, since the preview size may become larger than the originals (especially if you use efficient image formats like HEIC). In this case, you can limit previews to a smaller size like `2048px`.
 
-Note that Memories will, by default, load the full image upon zooming in. If you are okay with this, you may use a even smaller size like `1024px` to save more space as well as faster preview generation time. Non-JPEG files will be converted on the server when loading in full-res, which may lead to some server load.

+## Header Logo
+
+Nextcloud supports customizing the logo for your instance. To properly theme the logo to match the user's theme, the logo you use in `Admninistration => Theming` must follow the following criteria:
+
+- It must be an SVG file.
+- The `viewBox` attribute on the `<svg>` element must be set appropriately.
+- All paths that correspond to white areas must have the `fill` attribute set to `currentColor`. These areas will then automatically be colored according to the user's theme.
+- Since Nextcloud doesn't support `currentColor`, you must set the default value for the color (e.g. `white`) as an inline style on the `<svg>` element (`<svg style="color:white">`).
+
+A sample SVG that follows these criteria is shown below (from [here](https://github.com/pulsejet/memories/blob/master/src/assets/nextcloud.svg)):
+
+```xml
+--8<-- "src/assets/nextcloud.svg"
+```
+
+Note that you may skip these steps and also use a PNG file, but the logo will not be colored according to the user's theme. This can be especially troublesome since Nextcloud mostly shows the logo on a dark background while Memories uses both light and dark backgrounds.

 ## Other notes
 
-- For optimal performance, enable HTTP/2 on your reverse proxy (nginx/apache)
 - Make sure your server timezone is configured correctly. If a photo does not contain an EXIF date, the server time is used.
-- Perform additional server tuning for Nextcloud. See [the docs](https://docs.nextcloud.com/server/latest/admin_manual/installation/server_tuning.html).
-- The archive feature moves photos to a separate folder called `.archive` at the root of your timeline. You can, for example, mount this folder to a cold storage.
