! Major Improvements

!! Conditional Shortcut Syntax

<<.link-badge-added "https://github.com/TiddlyWiki/TiddlyWiki5/pull/7710">> a new [[shortcut syntax|Conditional Shortcut Syntax]] for concisely expressing if-then-else logic. This is the first of a new type of wikitext syntax based on tokens delimited with `<%` and `%>`. We plan to introduce other structures using the same format such as a "case" statement.

These new token-based shortcuts allow a richer structure and expressivity than existing features such as widgets or pragmas. For example:

```
<% if [<animal>match[Elephant]] %>
  It is an elephant
<% elseif [<animal>match[Giraffe]] %>
	It is a giraffe
<% else %>
	It is completely unknown
<% endif %>
```

Behind the scenes, the conditional shortcut syntax is rendered as the equivalent [[ListWidgets|ListWidget]].

!! Explicit Templates for the ListWidget

<<.link-badge-added "https://github.com/TiddlyWiki/TiddlyWiki5/pull/7784">> support for `<$list-template>` and `<$list-empty>` as immediate children of the <<.wid "ListWidget">> widget to specify the list item template and/or the empty template.

This new feature is designed to replace a common pattern of using the `emptyMessage` attribute of the ListWidget to render complex wikitext that thus has to be quoted. Working with wikitext within quotes is awkward and error prone. The new structure can be somewhat faster because it allows the empty message to be parsed in advanced of rendering.

For example:

```
<$list filter=<<filter>>>
	<$list-template>
		<$text text=<<currentTiddler>>/>
	</$list-template>
	<$list-empty>
		None!
	</$list-empty>
</$list>
```

Note that the <<.attr "emptyMessage">> and <<.attr "template">> attributes take precedence if they are present.

!! Joiners for the ListWidget

<<.link-badge-added "https://github.com/TiddlyWiki/TiddlyWiki5/pull/7694">> a <<.attr "join">> attribute to the <<.wid "ListWidget">> widget to insert a short piece of text between list items. This is both easier to use and faster than using the <<.attr "counter">> attribute for the same purpose. So if your list looked like this:

```
<$list filter=<<filter>> counter="counter" variable="item">
<$text text=<<item>>/><$list filter="[<counter-last>match[no]]" variable="ignore"><$text text=", "/></$list>
</$list>
```

You can replace it with:

```
<$list filter=<<filter>> variable="item" join=", "><$text text=<<item>>/></$list>
```

If the joiner text that you need is long and awkward to write in an attribute, you can use the new `<$list-join>` widget. Like `<$list-template>` and `<$list-empty>`, it must be an immediate child of the <<.wid "ListWidget">>:

```
<$list filter=<<filter>> variable="item"><$text text=<<item>>/><$list-join>, and <em>also</em> let's not forget </$list-join></$list>
```

!! jsonset operator
