+The Newsletter Team is responsible for producing the [[TiddlyWiki Newsletter]]. We would love to have your help if you would like to get involved.
+
+! Audience
+
+The newsletter is intended for TiddlyWiki end users who do not track all the discussions on https://talk.tiddlywiki.org/.
+
+Coverage of developer topics such as JavaScript and intricate wikitext should be handled thoughtfully to avoid alienating the core audience of end users.
+
+Subscribing to the newsletter is intended to give people confidence that they will not miss any important developments.

-modified: 20241009171916728
-tags: Community
-
-The ~TiddlyWiki Newsletter is produced by a small team of volunteers. We would love to have your help if you want to get involved.
-
-! Team
-
-The newsletter team currently consists of:
-
-* [[@jeremyruston|https://talk.tiddlywiki.org/u/jeremyruston]]
-* [[@CodaCoder|https://talk.tiddlywiki.org/u/codacoder]]
-* [[@Springer|https://talk.tiddlywiki.org/u/springer]]
-
-! Audience
-
-The newsletter is intended for TiddlyWiki end users who do not track all the discussions on https://talk.tiddlywiki.org/.
-
-Coverage of developer topics such as JavaScript and intricate wikitext should be handled thoughtfully to avoid alienating the core audience of end users.
-
-Subscribing to the newsletter should give people confidence that they will not miss any important developments.
-
-! Process
-
-The process is:
-
-# Determine which discussion forum threads should be included
-# Decide whether to link to the thread itself or to link to the subject of the thread
-# Write a 30-70 word introduction
-# Optionally, choose or make an image/screenshot to illustrate the story
-
-These steps are described in more detail below.
-
-!! Criteria for Inclusion
-
-The criteria for inclusion are necessarily loose. Editorial judgement is required to decide whether an item is sufficiently interesting to a broad enough audience.
-
-Important categories of threads that should be considered:
-
-* All announcements of new releases of TiddlyWiki and TiddlyDesktop
-* Community news and developments
-* New plugins
-* Updates to widely used plugins
-* Showcases of interesting TiddlyWiki's in the wild
-
-!! Linking
-
-In most cases, news items should link to the opening post in the corresponding thread. There might be situations where it makes more sense to link to the item concerned which will be listed here.
-
-!! Writing News Items
-
-Items would be a 30-70 word introduction with a link, and optionally an image (the newsletter looks much more inviting with some images included).
-
-!! Images
-
-Well chosen images can be informative and add visual interest to the newsletter as a whole. Some points to consider when choosing an image:
-
-* Images that work best of all are those that trigger an emotional response by including a human face. It is fairly unlikely that a ~TiddlyWiki news story would have a reason to be illustrated by a picture of a smiling baby, but we should strive to do so if we can
-* If using a screenshot, remember that the image will be displayed fairly small in the newsletter so it is better to crop screenshots to show a smaller area of interest rather than the entire browser window
-* Avoid using AI generated images

-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 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.

+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`.

 ! Introduction
 
-<<.from-version "5.1.23">> The ''action-log'' widget is an [[action widget|ActionWidgets]] that can be used to output debugging information to the [[JavaScript console|Web Developer Tools]] supported by most browsers. This can be useful because otherwise it is difficult to observe what is going on within a sequence of actions.
+<<.from-version "5.1.23">> The <<.wid action-log>> widget is an [[action widget|ActionWidgets]] that can be used to output debugging information to the [[JavaScript console|Web Developer Tools]] supported by most browsers. This can be useful to observe and debug the behavior within a sequence of actions.
+
+When the action is invoked, the names and values of all [[attributes|Widget Attributes]] are logged to the JavaScript console.
+
+```
+<$action-log name=value />
+```
 
 ActionWidgets are used within triggering widgets such as the ButtonWidget.
 
-<<.tip """ For debugging outside of actions see [[LogWidget]]""">>
+<<.note """ For debugging outside of actions see [[LogWidget]]""">>
 
 ! Content and Attributes
 
-The ''action-log'' widget is invisible. Any content within it is ignored.
-
-When the actions are invoked, the names and values of all attributes are logged to the JavaScript console.
-In addition there are optional attributes that can be used:
-
-|!Optional Attribute |!Description |
-|$$filter|All variables matching this filter will also be logged. |
-|$$message |A message to display as the title of the information logged. Useful when several `action-log` widgets are used in sequence. |
-|$$all |Set to "yes" to log all variables in a collapsed table. Note that if there is nothing specified to log, all variables are always logged instead.|
+The <<.wid action-log>> widget is invisible. Any content within it is ignored.
 
 <<.from-version "5.4.0">> Any [[multi-valued variables|Multi-Valued Variables]] or attributes are logged as a list of values.
 
-<<.tip """A handy tip if an action widget is not behaving as expected is to temporarily change it to an `<$action-log>` widget so that the attributes can be observed.""">>
+|!Attribute |!Description |
+|<<.attr $$filter>>|(Optional) All variables whose name matches the [[Filter Expression]] will be logged |
+|<<.attr $$message>> |(Optional) A message to display as the title of the information logged. Useful when several <<.wid action-log>> widgets are used in sequence |
+|<<.attr $$all>> |(Optional) Set to <<.value yes>> to log all variables |
 
-! Example
+<<.note """ If `<$action-log />` is called without any attributes, all defined variables will be logged as if `$$all=yes` were set.""">>
 
-Here is an example of logging two variables:
+<<.note """When logging [[Variable Attribute Values]], the body text of macros and procedures will be output as their value. Functions are evaluated and their first result is logged.""">>
+
+! Examples
+
+!! Basic Example
+
+Log the value of variable <<.var name>>, the first result of the filter expression `[tag[Learning]]` and the value of field <<.field created>> of the current tiddler:
 
 ```
-<$action-log myVar=<<myVar>> otherVar=<<otherVar>>/>
+<$action-log name=<<name>> filter={{{ [tag[Learning]] }}} created={{!!created}} />
 ```
 
-To log all variables:
+!! Example using <<.attr $$filter>> and <<.attr $$message>> 
+
+Log all core variables (which start with <<.var tv->>) with a table title:
 
 ```
-<$action-log />
+<$action-log $$message="Core Variables" $$filter="[prefix[tv-]]" />
 ```
 
+!! Widget Debugging
 
-To log two variables as well as all core variables (which start with `tv-`):
+Change a misbehaving <<.wlink ActionSetFieldWidget>> widget to an <<.wid action-log>> widget to verify that <<.var currentTiddler>> and <<.var value>> match their expected values:
+
+<<.tip """If an action widget is not behaving as expected it is often useful to temporarily change it to an <<.wid action-log>> widget so that the passed attributes can be verified.""">>
 
 ```
-<$action-log myVar=<<myVar>> other={{!!status}} $$filter="[prefix[tv-]]"/>
+<$action-log $tiddler=<<currentTiddler>> $field="text" $value=<<value>> />
 ```
+
+This application is the primary reason that the attributes of the <<.wid action-log>> widget are prefixed with two dollar signs instead of one. Otherwise, the attributes of the original widget could be interpreted as attributes to <<.wid action-log>> and lead to unintended consequences.
+
+!! Example with Function
+
+Log the <<.var tiddlerList>> function definition and its first evaluation result:
+
+```
+\function tiddlerList() [tag[Learning]]
+
+<$action-log $$filter="[title[tiddlerList]]" value=<<tiddlerList>> />
+```
+
+<<.note """The values output with the <<.attr $$filter>> or <<.attr $$all>> attributes will only contain the definition of functions instead of their values, as the evaluation of many functions can lead to significant performance penalties.""">>
