v2.1.0-beta

## What's Changed

 **Security**:
 - [Moderate] Conflicting upload responses no longer synchronously drain the request body before returning HTTP 409; the server now closes the body and marks the connection for closure, preventing denial-of-service from clients that never send EOF (CWE-400).
 - Share download links no longer create links with token, instead they link to the UI prompting for password before download. If a direct download is required, the `/api/share/direct` api exists and documented by swagger. (#2888)

 **New Features**:
 - Added Storage Quotas
   - configurable by folder, source, user, and share.
   - Administrators can create, edit, view, and delete folder quotas through the interface.
   - Quota information now appears in source views, share details, sidebar progress bars, and folder prompts.
 - Enhancements to the editor (#2714):
   - Added a floating button to open a resizable split view with live editing for markdown files, the scrolling is synced in both sides and scrolling in single-view modes (the viewer and editor in non-split) now also tries to sync with each other so you don't lose context easily.
   - Added a toolbar: This toolbar is present on all the files.
     - JSON files have a button to toggle between formatted and minified versions (#2854) (#2566).
     - Markdown files have a richer toolbar with lots of quick actions, for example you can now browse, navigate and insert images more easily from your current source.
   - Added a prompt to configure some editor settings in UI, that prompt is accessible via the toolbar in the three-dots menu, there you can configure things like:
     - Word wrap, keybinds, autocompletion, scrollbar, etc.
   - The markdown viewer now supports rendering LaTeX Math and Chemistry formulas.
   - Improved and fixed some styles that weren't following the app light/dark theme (#2949).
 - Proxy auth group support: `groupsClaim`, `adminGroup`, and `userGroups` now control role-based access when the proxy sends a group/role header (#2755). Admin is determined by `adminGroup` only.
 - Support for `.elrc` (word-by-word lyrics), `.vtt`, `.srt` sidecar files for lyrics in audio files in the media player. (#2838)
 - Added setting to configure the placement of the prompts close button in profile settings (#2853) (#2595).
 - Added "New file templates". You can now add and configure pre-defined filenames + extension for the creation of new files in the context menu on profile settings! (#2881) (#1239).
 - sidebar links can be bulk edited as yaml (#1963) (settings > user management)
 - admins can customize more defaults:
   - share creation defaults and enforcements (#1692) (#2434) (#2279) (#2812) (settings > share management)
   - sidebar link defaults and enforcements (#2561) (settings > user management)
   - tool defaults and enforcement (settings > user management)
 - Sort header in file listings inside prompts like move/copy/quick jump, is now sticky. Also added a button to show a search input and filter the items of the current listing (#3028).
 - Quick jump now scrolls and highlights the current item you are previewing (#3028).
 - When hovering `date` and `name` in the listings, will show up the formatted/raw date (the inverse of what you have configured to display) and the full filename (#3028) (#2623).
 - User groups can now be managed from the WebUI under `User Management` -> `Groups` and when editing a user (#2983) (#3040).

 **Notes**:
 - Moved `auth.adminUsername` and `auth.adminPassword` to `auth.methods.password` (legacy top-level keys are migrated automatically on load).
 - An Admin can remove a `defautlEnabled` source for a user and it will remove removed until an admin adds it back.
 - Enhancements to cross-source copy/move permissions and behavior.
 - Improved resume upload behavior.
 - Play/pause on videos in mobile now is toggled by the button in the middle rather than the whole container (#2828).
 - improved video thumbnail generation speed and efficiency.
 - Added icons based on extension to the upload prompt and new file/folder/rename prompts (#2881).
 - Profile settings show minimal options by default. Full advanced profile settings can be shown by default by enabling `account.showAdvancedProfile`.
 - sidebar links/navigation is button group toggle for clearer visibility
 - Pop-up preview has 200ms debounce delay so it doesn't flash from moving the cursor across files quickly.
 - Polished a bit some styles across various places of the UI (#3019) (#3028).
 - Moved `Access Management` under `User Management` in the UI (#3040).
 - improved developer experience with native vue webhook reloads.
 - improved ffmpeg handling and concurrency via library upgrades

 **Bug Fixes**:
 - Undo in a fresh opened file on the editor was setting the file empty (#2714)
 - Added some missing styles in the markdown viewer (#2714)
 - Recaptcha not working (#1925) (#2861)
 - Fix disk-usage overstatement on virtiofs bind mounts (#2894)
 - Support non-ASCII share passwords (#2933)
 - Fall back to buffered copies when FUSE rejects fast paths (#2938)
 - Preserve deleted sidebar links across restarts (#2935)
 - scope padding to listing view (#2934)
 - Hide the Replace option on upload/create conflict prompts when the user lacks modify permission (or when a public share disallows replacements), so create-only users are not offered an action that the server rejects (#2837)
 - Preserve Ctrl-click file selection when keyboard state is stale (#2958) (#2923)
 - Avoid false stalls during parallel transfers (#2950) (#2948) thanks @gudcks0305
 - Cap source usage-bar percentage at 100% when indexed size exceeds partition total (#2761) (#2238)
 - On Linux, source partition totals sum distinct filesystems mounted under the source root (nested mounts) so usage bars match indexed content (#2761)
 - Context menu stuck when opened from a listing in a prompt like move/copy or search (#3028).
