 ! Major Improvements
 
+!! Tour Plugin
+
+<<.link-badge-added "https://github.com/Jermolene/TiddlyWiki5/pull/7734">> several new features that together allow interactive learning tours to be created and presented in TiddlyWiki.
+
+The demo TiddlyWiki interactive tour can be seen at https://tiddlywiki.com/prerelease/tour
+
+The new features include:
+
+* The new Tour Plugin itself
+* The new Confetti Plugin that allows animated bursts of confetti to be displayed
+* Improvements to the Dynannotate Plugin to add the ability to highlight screen elements using an animated spotlight effect
+
+!! <<.wlink TestCaseWidget>> Widget
+
+<<.link-badge-added "https://github.com/Jermolene/TiddlyWiki5/pull/7817">> new <<.wlink TestCaseWidget>> widget that is intended to solve a problem with the examples that we feature in the documentation. The existing macros are workable for simple, self-contained examples, but can be hard to follow in cases where the examples use additional tiddlers. The <<.wlink TestCaseWidget>> widget displays complete, self-contained interactive examples showing the output together with a tabbed display of the constituent tiddlers that produce it:
+
+<<testcase "TestCases/TestCaseWidget/TwoPlusTwo">>
+
+The payload tiddlers for a test case are specified with the <<.wlink DataWidget>> widget. Test cases are run as an independent, self-contained nested wiki in a similar way to the [[Innerwiki Plugin]], but are much more lightweight. The disadvantage is that test cases are rendered as part of the main page, and so any styling changes will leak out to the rest of the page.
+
+Test cases can also specify the raw HTML of the expected result which causes them to be executed as tests, with success or failure indicated by an icon:
+
+<<testcase "TestCases/TestCaseWidget/FailingTest">>
+
+The easiest way to use the <<.wlink TestCaseWidget>> is by creating TestCaseTiddlers using the new CompoundTiddlers format. There are also many test cases to view in the TiddlyWiki test edition at https://tiddlywiki.com/prerelease/test.html

+
+Compound tiddlers are a special type of tiddler that can store one or more payload tiddlers. The tiddlers within a compound tiddler are only accessible via special operations, typically with the TestCaseWidget.
+
+The compound tiddler format is extremely simple, and includes the notable flaw that it does not permit tiddlers that contain a plus sign (`+`) on a line by itself. It is not intended as a general purpose way of storing tiddler data.
+
+Compound tiddlers are identified by having their type field set to `text/vnd.tiddlywiki-multiple`.
+
+The content of a compound tiddler consists of a sequence of tiddlers separated by a plus sign (`+`) on a line by itself. Each tiddler uses the same format as [[.tid files|TiddlerFiles]].
+
+For example:
+
+```
+title: First
+tags: one two
+
+This is the first tiddler
++
+title: Second
+tags: three four
+
+This is the second tiddler
++
+title: third
+tags: five six
+
+This is the third tiddler
+```

+Test case tiddlers encapsulate one or more tiddlers that can be displayed as a [[test case|TestCaseWidget]]: an independent embedded wiki that can be used for testing or learning purposes.
+
+Test case tiddlers are formatted as CompoundTiddlers, allowing them to contain multiple tiddlers packed into one.

+Test case tiddlers have the following fields:

+|!Field |!Description |
+|<<.field type>> | Should be set to `text/vnd.tiddlywiki-multiple` |
+|<<.field tags>> | Test cases are tagged [[$:/tags/wiki-test-spec]]. Test cases that intentionally fail are tagged [[$:/tags/wiki-test-spec-failing]] |
+|<<.field description>> |Descriptive heading for the test, intended to make it easy to identify the test |
+|<<.field display-format>> |Optional, defaults to `wikitext`. Set to `plaintext` to cause the output to be rended as plain text |
+
+Test case tiddlers with the appropriate tag are shown in $:/ControlPanel
+
+Some payload tiddlers are set aside for special purposes:
+
+|!Tiddler |!Description |
+|''Narrative'' |Narrative description of the test, intended to explain the purpose and operation of the test |
+|''Output'' |The tiddler that produces the test output |
+|''~ExpectedResult'' |HTML of expected result of rendering the ''Output'' tiddler |

 If a [[list widget|ListWidget]] generates multiple tag macros for the same tag, clicking any of them opens dropdowns on all of them, as in the example below. This is usually unwanted.
-<$macrocall $name=".example" n="3" eg="""<$list filter="[tag[HelloThere]]">

 * <$link/> is tagged with: <$list filter="[<currentTiddler>tags[]]"> <<tag>> </$list>
 
 </$list>"""/>
 
 Adding the `counter="transclusion"` attribute to the list widget that generates multiple identical tag macros causes each of them to be identified as a unique one. Clicking on any of them opens only a single dropdown.
-<$macrocall $name=".example" n="4" eg="""<$list filter="[tag[HelloThere]]" counter="transclusion">
+<$macrocall $name=".example" n="5" eg="""<$list filter="[tag[HelloThere]]" counter="transclusion">
 
 * <$link/> is tagged with: <$list filter="[<currentTiddler>tags[]]"> <<tag>> </$list>
 
 </$list>"""/>
 
 A slightly more performant option is to use the `variable="transclusion"` attribute in the list widget. In this case, the variable `<<transclusion>>` has to be used inside the list widget instead of the `<<currentTiddler>>` .
-<$macrocall $name=".example" n="5" eg="""<$list filter="[tag[HelloThere]]" variable="transclusion">

+Plugins are recommended to have a `stability` field that communicates the state of development of the plugin. It can contain the following values:
+
+* ''STABILITY_0_DEPRECATED'' - Deprecated. This plugin is not recommended for new projects
+* ''STABILITY_1_EXPERIMENTAL'' - Experimental. Non-backward compatible changes or removal may occur in any future release. Use of the plugin is not recommended in production environments
+* ''STABILITY_2_STABLE''  - Stable.
+* ''STABILITY_3_LEGACY'' - Legacy. Although this plugin is unlikely to be removed, it is no longer actively maintained, and other alternatives are available
+
+These stability levels are taken from the Node.js project - https://nodejs.org/api/documentation.html#stability-index.
