<h4>Features</h4>
<ul>
<li>Hint comments in exercises now also include a reference to the
<code>hint</code> watch mode subcommand.</li>
<li><strong>intro1</strong>: Added more hints to point the user to the source file.</li>
<li><strong>variables</strong>: Switched variables3 and variables4.</li>
<li>Moved <code>vec</code> and <code>primitive_types</code> exercises before <code>move_semantics</code>.</li>
<li>Renamed <code>vec</code> to <code>vecs</code> to be more in line with the naming in general.</li>
<li>Split up the <code>collections</code> exercises in their own folders.</li>
<li><strong>vec2</strong>: Added a second part of the function that provides an alternative,
immutable way of modifying vec values.</li>
<li><strong>enums3</strong>: Added a hint.</li>
<li>Moved <code>strings</code> before <code>modules</code>.</li>
<li>Added a <code>strings3</code> exercise to teach modifying strings.</li>
<li>Added a <code>hashmaps3</code> exercise for some advanced usage of hashmaps.</li>
<li>Moved the original <code>quiz2</code> to be <code>strings4</code>, since it only tested strings
anyways.</li>
<li>Reworked <code>quiz2</code> into a new exercise that tests more chapters.</li>
<li>Renamed <code>option</code> to <code>options</code>.</li>
<li><strong>options1</strong>: Rewrote parts of the exercise to remove the weird array
iteration stuff.</li>
<li>Moved <code>generics3</code> to be <code>quiz3</code>.</li>
<li>Moved box/arc exercises behind <code>iterators</code>.</li>
<li><strong>iterators4</strong>: Added a test for factorials of zero.</li>
<li>Split <code>threads1</code> between two exercises, the first one focusing more on
<code>JoinHandle</code>s.</li>
<li>Added a <code>threads3</code> exercises that uses <code>std::sync::mpsc</code>.</li>
<li>Added a <code>clippy3</code> exercises with some more interesting checks.</li>
<li><strong>as_ref_mut</strong>: Added a section that actually tests <code>AsMut</code>.</li>
<li>Added 3 new lifetimes exercises.</li>
<li>Added 3 new traits exercises.</li>
</ul>
<h4>Bug Fixes</h4>
<ul>
<li><strong>variables2</strong>: Made output messages more verbose.</li>
<li><strong>variables5</strong>: Added a nudging hint about shadowing.</li>
<li><strong>variables6</strong>: Fixed link to book.</li>
<li><strong>functions</strong>: Clarified the README wording. Generally cleaned up
some hints and added some extra comments.</li>
<li><strong>if2</strong>: Renamed function name to <code>foo_if_fizz</code>.</li>
<li><strong>move_semantics</strong>: Clarified some hints.</li>
<li><strong>quiz1</strong>: Renamed the function name to be more verbose.</li>
<li><strong>structs1</strong>: Use an integer type instead of strings. Renamed "unit structs"
to "unit-like structs", as is used in the book.</li>
<li><strong>structs3</strong>: Added the <code>panic!</code> statement in from the beginning.</li>
<li><strong>errors1</strong>: Use <code>is_empty()</code> instead of <code>len() &gt; 0</code></li>
<li><strong>errors3</strong>: Improved the hint.</li>
<li><strong>errors5</strong>: Improved exercise instructions and the hint.</li>
<li><strong>errors6</strong>: Provided the skeleton of one of the functions that's supposed
to be implemented.</li>
<li><strong>iterators3</strong>: Inserted <code>todo!</code> into <code>divide()</code> to keep a compiler error
from happening.</li>
<li><strong>from_str</strong>: Added a hint comment about string error message conversion with
<code>Box&lt;dyn Error&gt;</code>.</li>
<li><strong>try_from_into</strong>: Fixed the function name in comment.</li>

<h4>Removed</h4>
<ul>
<li>Removed the legacy LSP feature that was using <code>mod.rs</code> files.</li>
<li>Removed <code>quiz4</code>.</li>
<li>Removed <code>advanced_errs</code>. These were the last exercises in the recommended
order, and I've always felt like they didn't quite fit in with the mostly
simple, book-following style we've had in Rustlings.</li>
</ul>
<h4>Housekeeping</h4>
<ul>
<li>Added missing exercises to the book index.</li>
<li>Updated spacing in Cargo.toml.</li>
<li>Added a GitHub actions config so that tests run on every PR/commit.</li>
</ul>

<h4>Features</h4>
<ul>
<li>The amount of dependency crates that need to be compiled went down from ~65 to
~45 by bumping dependency versions.</li>
<li>The minimum Rust version in the install scripts has been bumped to 1.56.0 (this isn't in
the release itself, since install scripts don't really get versioned)</li>
</ul>
<h4>Bug Fixes</h4>
<ul>
<li><strong>arc1</strong>: A small part has been rewritten using a more functional code style (#968).</li>
<li><strong>using_as</strong>: A small part has been refactored to use <code>sum</code> instead of <code>fold</code>, resulting
in better readability.</li>
</ul>
<h4>Housekeeping</h4>
<ul>
<li>The changelog will now be manually written instead of being automatically generated by the
Git log.</li>
