<blockquote>
<h1>1.4.5 (2021-03-14)</h1>
<p>This is a small patch release that fixes a regression in the size of a <code>Regex</code>
in the 1.4.4 release. Prior to 1.4.4, a <code>Regex</code> was 552 bytes. In the 1.4.4
release, it was 856 bytes due to internal changes. In this release, a <code>Regex</code>
is now 16 bytes. In general, the size of a <code>Regex</code> was never something that was
on my radar, but this increased size in the 1.4.4 release seems to have crossed
a threshold and resulted in stack overflows in some programs.</p>
