<blockquote>
<h2>1.11.0</h2>
<p>This release is based on Kotlin 2.3.20 and provides a new Json
exceptions API and some bugfixes and improvements.</p>
<h2>Expose Json exceptions structure</h2>
<p>To make working with exceptions easier and providing proper error
codes in e.g., REST APIs,
classes <code>JsonException</code>, <code>JsonDecodingException</code>,
and <code>JsonEncodingException</code> are now public.
They have relevant public properties, such as <code>shortMessage</code>,
<code>path</code>, <code>offset</code>, and others.
This API is currently experimental, and we're going to improve it
further in the subsequent releases.
See the linked issues for the details: <a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/1930">#1930</a>,
<a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/1877">#1877</a>.</p>
<h2>Ability to hide user input from exception messages for
security/privacy reasons.</h2>
<p>Historically, exception messages in kotlinx.serialization often
included the input Json itself for debuggability reason.
Such behavior may pose additional challenges for logging, analytics, and
other systems, since
a system is not always allowed to store user data due to
privacy/security reasons, which imposes additional sanitation logic.
To address this issue, a new property
<code>exceptionsWithDebugInfo</code> is added to
<code>JsonConfiguration</code>.
Disable it to hide user input from exception messages.
IMPORTANT: This behavior will be enabled by default when this property
becomes stable.
See <a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/2590">#2590</a>
for more details.</p>
<h2>Bugfixes and improvements</h2>
<ul>
<li>CBOR: Relax value range check when decoding numbers (<a
href="https://redirect.github.com/Kotlin/kotlinx.serialization/issues/3167">#3167</a>)</li>
<li>Use a specialized writeDecimalLong method for IO stream integrations
in Json (<a
