<h4>Fix leading comments in mapped types with <code>readonly</code> (<a href="https://github-redirect.dependabot.com/prettier/prettier/pull/13427">#13427</a> by <a href="https://github.com/thorn0"><code>@​thorn0</code></a>, <a href="https://github.com/sosukesuzuki"><code>@​sosukesuzuki</code></a>)</h4>

<pre lang="tsx"><code>// Input
type Type = {
  // comment
  readonly [key in Foo];
};
<p>// Prettier 2.8.3
type Type = {
readonly // comment
[key in Foo];
};</p>
<p>// Prettier 2.8.4

<h4>Group params in opening block statements (<a href="https://github-redirect.dependabot.com/prettier/prettier/pull/14067">#14067</a> by <a href="https://github.com/jamescdavis"><code>@​jamescdavis</code></a>)</h4>
<p>This is a follow-up to <a href="https://github-redirect.dependabot.com/prettier/prettier/issues/13930">#13930</a> to establish wrapping consistency between opening block statements and else blocks by
grouping params in opening blocks. This causes params to break to a new line together and not be split across lines
unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the
same as opening blocks.</p>

<pre lang="hbs"><code>{{! Input }}
{{#block param param param param param param param param param param as |blockParam|}}
  Hello
{{else block param param param param param param param param param param as |blockParam|}}
  There
{{/block}}
<p>{{! Prettier 2.8.3 }}
{{#block
param
param
param
param
param
&lt;/tr&gt;&lt;/table&gt;
