title: Notes for upgrading to 5.0.8-beta
type: text/vnd.tiddlywiki

Version 5.0.8-beta includes some changes that can break content from earlier releases of ~TiddlyWiki 5.

! Change to [[$:/SiteTitle]] and [[$:/SiteSubtitle]]

You should rename any existing SiteTitle and SiteSubtitle tiddlers to [[$:/SiteTitle]] and [[$:/SiteSubtitle]] respectively.

! Changed parsing rules for content of HTML elements

Version 5.0.8-beta marks a change in the way that TiddlyWiki determines whether to parse the content of an HTML element or widget in //block mode// or //inline mode//.

* In block mode, TiddlyWiki parses text into paragraphs, creating `<p>` tags to wrap them. It also recognises block syntax like headings, lists and tables.

* In inline mode, TiddlyWiki ignores paragraph formatting, and just recognises character formatting, like bold and italic.

It's important to be able to control which type of parsing is performed for different situations.

Prior to 5.0.8-beta, TiddlyWiki parsed the content of an element in inline mode unless the opening tag of the element were immediately followed by a line break. This meant that much of the time element tags would be shunted together into a long line, hindering readability.

The new behaviour for 5.0.8-beta is to parse the content of an element in inline mode unless the opening tag is immediately followed by two line breaks.

To adjust existing content for 5.0.8-beta you will need to manually add the additional line break after the opening tag of elements and widgets whose content should be parsed in block mode.

The positive aspect of the change is that it removes the need to pack multiple HTML tags onto a single line, improving readability.

!! Examples

Consider the difference between these two examples. First, here's an HTML tag that starts with two line breaks:

<<wikitext-example src:"
<blockquote>

! This is a heading

And a paragraph of text.

</blockquote>
">>

Secondly, here's an HTML tag with just a single line break. Notice how the heading is no longer recognised as a heading

<<wikitext-example src:"
<blockquote>
! This is a heading

And a paragraph of text.
</blockquote>
">>

! Changed commands for [[TiddlyWiki on Node.js]]

The handling of wiki folders has changed. Previously, if the `tiddlywiki` command was run against a wiki folder that didn't have the necessary `tiddlywiki.info` file then it would be automatically created. Now, the wiki folder must be initialised with the InitCommand.

This is how to create and start a new server-based wiki:

```
tiddlywiki mywikifolder --init server
tiddlywiki mywikifolder --server
```

Note that the name of the ''clientserver'' edition has changed to ''server''.
