<blockquote>
<h2>v0.29.0 - 2023-03-20</h2>
<h3>Added</h3>
<ul>
<li>Added support for <code>extended-const</code> Wasm proposal. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/707">paritytech/wasmi#707</a>)</li>
<li>Added fuel consumption modes. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/706">paritytech/wasmi#706</a>)
<ul>
<li>This allows eager and lazy fuel consumption modes to be used which
mainly affects bulk operations such as <code>table.copy</code> and
<code>memory.grow</code>.
Eager fuel consumption always consumes fuel before a bulk operation for
the
total amount independent of success or failure of the operation whereras
lazy fuel consumption only consumes fuel for successful executions.</li>
</ul>
</li>
</ul>
<h3>Changed</h3>
<ul>
<li>Normalize fuel costs of all instructions. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/705">paritytech/wasmi#705</a>)
<ul>
<li>With this change most instructions cost roughly 1 fuel upon
execution.
This is more similar to how Wasmtime deals with fuel metered instruction
costs.
Before this change <code>wasmi</code> tried to have fuel costs that more
closely mirror
the computation intensity of the respective instruction according to
benchmarks.</li>
</ul>

<h2>[<code>0.28.0</code>] - 2023-03-01</h2>
<h3>Added</h3>
<ul>
<li>Added support for the <code>tail-call</code> Wasm proposal. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/683">paritytech/wasmi#683</a>)</li>
<li>Added support for <code>Linker</code> defined host functions. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/692">paritytech/wasmi#692</a>)
<ul>
<li>Apparently this PR introduced some performance wins for the Wasm
target according to our tests.
This information shall be taken with a grain of salt since we are not
sure why those performance
improvement occured since the PR's functionality is orthogonal to Wasm
engine performance.</li>
<li>Required precursor refactoring PR: <a
href="https://redirect.github.com/paritytech/wasmi/pull/681">paritytech/wasmi#681</a></li>
</ul>
</li>
</ul>
<h3>Changed</h3>
<ul>
<li>The <code>wasmi_wasi</code> crate now more closely mirrors the
<code>wasmtime_wasi</code> crate API. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/700">paritytech/wasmi#700</a>)</li>
</ul>
<h3>Internal</h3>
<ul>
<li>Refactor the <code>wasmi</code> Wasm engine to handle Wasm calls and
returns in its core. [(<a
href="https://redirect.github.com/paritytech/wasmi/issues/694">#694</a>)]
<ul>
<li>This improved performance of Wasm function calls significantly at
the cost of host function call performance.</li>
<li>Also this seemed to have impacts Wasm target performance quite
positively, too.</li>
</ul>
</li>
<li>The <code>Store</code> now handles Wasm functions and host functions
separately. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/686">paritytech/wasmi#686</a>)
<ul>
<li>This allows to store Wasm functions into the <code>StoreInner</code>
type which was an important
step towards the major refactoring in [(<a
href="https://redirect.github.com/paritytech/wasmi/issues/694">#694</a>)]</li>
<li>It was expected that host function call performance would degrade by
this PR but our tests
actually showed that the opposite was true and Wasm target performance
was improved overall.</li>
</ul>
</li>
<li>Introduce <code>ValueStackPtr</code> abstraction for the
<code>wasmi</code> engine core. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/688">paritytech/wasmi#688</a>)
<ul>
<li>This change significantly improved performance especially on the
Wasm target according to our tests.</li>
</ul>
</li>
<li>Optimize <code>memory.{load,store}</code> when reading or writing
single bytes. (<a
href="https://redirect.github.com/paritytech/wasmi/pull/689">paritytech/wasmi#689</a>)</li>
