This is a very big release since v1.31.4. If you've used phtn.app, you won't notice a difference, since that runs on the latest commit.
TL;DR
Photon has been completely rewritten to use Svelte 5
This brings significant performance improvements
The UX has been changed to fit Photon's philosophy more closely
Many issues have been resolved and bugs fixed
60% of changes are under the hood, but there's many visible ones too
What you'll notice
Snappier performance
Svelte 5 optimizes a lot of the reactive parts of the app
I've also spent a lot of time on a new virtualizer, which runs a lot faster
Design changes
While the overall layout is relatively the same, I've reworked a lot of pages to fall more in line with my design philosophy.
The design across (most) pages is much more consistent
There's a new default theme
Compact mode is now the default (if you've used photon before, this will not affect your setting)
Comment layout is slightly different and more intuitive
Modals now create a backstack so you can press the back button on your browser
New features and options
More moderation features
Quickly view users'/submissions' moderation logs
View the users' votes n a post
Grouped reports for many reports on the same post
you can resolve many at once
Options for more granular control over how links work in posts
Option to reverse the action row
Option to use absolute timestamps
lemmy language tagging support
Command palette now has contextual navigation options
Contextual warnings for certain actions (like missing languages in posts)
Messages page has been overhauled with markdown, contextual actions, etc
Better view and options for modlog page
Donation dialog as Lemmy requested
Optimizations
Uses CSS animations more often which are faster
Uses svelte context API to reduce prop drilling
Navbar uses CSS rather than JS for positioning
Uses optimized svelte $state rather than stores

In the future
Piefed support is targeting v2.2.0
With the way it is being written, Mastodon support may as well come sometime around v3.0.0
There's a lot more in this release, as well as more to come. I'm trying to make Photon closer to its design philosophy, which can be summarized as:
It should not take more than 3 seconds to identify an action you wish to perform within a given container or page.
This covers a lot of reasons why I design stuff the way I do, for example, you'll never find more than 5 buttons (minus links) in a single container. Additionally, specific types of actions will usually look different, like primary actions on a page versus sub actions.
