This release includes additional improvements to the Go linker,
|
|
reducing linker resource usage (both time and memory) and improving
|
|
code robustness/maintainability. These changes form the second half
|
|
of a two-release project to
|
|
<a href="https://golang.org/s/better-linker">modernize the Go
|
|
linker</a>.
|
|
</p>
|
|
|
|
<p>
|
|
The linker changes in 1.16 extend the 1.15 improvements to all
|
|
supported architecture/OS combinations (the 1.15 performance improvements
|
|
were primarily focused on <code>ELF</code>-based OSes and
|
|
<code>amd64</code> architectures). For a representative set of
|
|
large Go programs, linking is 20-35% faster than 1.15 and requires
|
|
5-15% less memory on average for <code>linux/amd64</code>, with larger
|
|
improvements for other architectures and OSes.

|
|
The <a href="/pkg/unicode/"><code>unicode</code></a> package and associated
|
|
support throughout the system has been upgraded from Unicode 12.0.0 to
|
|
<a href="https://www.unicode.org/versions/Unicode13.0.0/">Unicode 13.0.0</a>,
|
|
which adds 5,930 new characters, including four new scripts, and 55 new emoji.
|
|
Unicode 13.0.0 also designates plane 3 (U+30000-U+3FFFF) as the tertiary
|
|
ideographic plane.
