-Under Windows it is possible to convert TiddlyWiki into a true local application by renaming the HTML file to have the extension `*.hta`. The ''fsosaver'' module can then use the ~ActiveX ~FileSystemObject to save changes.
-
-Note that one disadvantage of this approach is that the TiddlyWiki file is saved in UTF-16 format, making it up to twice as large as it would be with the usual UTF-8 encoding. However, opening and saving the file via another saving method will re-encode the file to UTF-8.

 This PR introduces a new filter run prefix `:let` that assigns the result of the filter run to a variable that is made available for the remaining filter runs of the filter expression. It solves the problem that previously it was impossible to compute values for filter operator parameters; parameters could only be a literal string, text reference or variable reference.

+
+This PR adds support for an info property to server route module exports. The info object may include a priority field, which determines the route’s order of precedence.
+
+Priorities are numeric and follow a descending order: routes with higher priority values are processed first, similar to how saver modules are prioritized.
+
+To maintain backward compatibility with existing code, any module that omits info or info.priority is assigned a default priority of 100. Core server routes have been updated to explicitly use this default value of 100.

+ViewToolbar buttons can now be conditionally displayed based on the currentTiddler using a `condition` field. Similar to how `$:/tags/Exporter` and `$:/tags/EditorTools` already have. An example would be:
+
+```tid
+tags: $:/tags/ViewToolbar
+condition: [<currentTiddler>type[text/x-markdown]] [<currentTiddler>type[text/markdown]]

+Fixed issue where the browser storage plugin caused the wiki to be marked as dirty every time it starts up. The problem was due to the use of a log tiddler titled `$:/info/browser/storage/persisted`, the fix is to rename it to `$:/state/browser/storage/persisted`.

+
+The DiffTextWidget now supports two additional diff modes via the `mode` attribute:
+
+* `mode="words"` - Performs word-level diff operations, making differences more intelligible when comparing text
+* `mode="lines"` - Performs line-level diff operations, highlighting entire lines that have changed
+
+The default `mode="chars"` continues to work as before, performing character-level diff operations.
