<blockquote>
<h2>[v0.5.0] - 2018-05-11</h2>
<h3>Added</h3>
<ul>
<li>
<p><code>DebugMonitor</code> and <code>SecureFault</code> variants to the <code>Exception</code> enumeration.</p>
</li>
<li>
<p>An optional <code>"inline-asm"</code> feature</p>
</li>
</ul>
<h3>Changed</h3>
<ul>
<li>
<p>[breaking-change] This crate now requires <code>arm-none-eabi-gcc</code> to be installed and available in
<code>$PATH</code> when built with the <code>"inline-asm"</code> feature disabled (which is disabled by default).</p>
</li>
<li>
<p>[breaking-change] The <code>register::{apsr,lr,pc}</code> modules are now behind the <code>"inline-asm"</code> feature.</p>
</li>
<li>
<p>[breaking-change] Some variants of the <code>Exception</code> enumeration are no longer available on
<code>thumbv6m-none-eabi</code>. See API docs for details.</p>
</li>
<li>
<p>[breaking-change] Several of the variants of the <code>Exception</code> enumeration have been renamed to
match the CMSIS specification.</p>
</li>
<li>
<p>[breaking-change] fixed typo in <code>shcrs</code> field of <code>scb::RegisterBlock</code>; it was previously named
<code>shpcrs</code>.</p>
</li>
<li>
<p>[breaking-change] removed several fields from <code>scb::RegisterBlock</code> on ARMv6-M. These registers are
not available on that sub-architecture.</p>
</li>
<li>
<p>[breaking-change] changed the type of <code>scb::RegisterBlock.shpr</code> from <code>RW<u8></code> to <code>RW<u32></code> on
ARMv6-M. These registers are word accessible only on that sub-architecture.</p>
</li>
<li>
<p>[breaking-change] renamed the <code>mmar</code> field of <code>scb::RegisterBlock</code> to <code>mmfar</code> to match the CMSIS
name.</p>
</li>
<li>
<p>[breaking-change] removed the <code>iabr</code> field from <code>scb::RegisterBlock</code> on ARMv6-M. This register is
not available on that sub-architecture.</p>
</li>
<li>
<p>[breaking-change] removed several fields from <code>cpuid::RegisterBlock</code> on ARMv6-M. These registers
are not available on that sub-architecture.</p>
</li>
<li>
<p>[breaking-change] The <code>Mutex.new</code> constructor is not a <code>const fn</code> by default. To make it a <code>const fn</code> you have to opt into the <code>"const-fn"</code> feature, which was added in v0.5.1, and switch to a
nightly compiler.</p>
</li>
</ul>
<h3>Removed</h3>
<ul>
<li>[breaking-change] The <code>exception</code> module has been removed. A replacement for <code>Exception::active</code>
can be found in <code>SCB::vect_active</code>. A modified version <code>exception::Exception</code> can be found in the
<code>peripheral::scb</code> module.</li>
</ul>
