CL 568340 - fixed a spurious race in time.Ticker.Reset (added via accepted proposal https://go.dev/issue/33184), doesn't seem to need a release note
CL 562619 - x/website CL documented minimum bootstrap version on go.dev, mentioning accepted proposals go.dev/issue/54265 and go.dev/issue/44505; doesn't need a release note

in practice any release ≥ Go 1.20.6 but < Go 1.x will work as the bootstrap base.
Releases ≥ Go 1.x are very likely to work as well.

See https://go.dev/s/go15bootstrap for more details about the original bootstrap

# Regression test for https://go.dev/issue/47215 and https://go.dev/issue/50183:
# A missing $CC caused the C dependencies of the net
# package to appear stale, and it could not be rebuilt due to a missing $CC.

[!cgo] skip

# This test may start with the runtime/cgo package already stale.
# Explicitly rebuild it to ensure that it is cached.
# (See https://go.dev/issue/50892.)
#
# If running in non-short mode, explicitly vary CGO_CFLAGS

#### Binary Distributions

Official binary distributions are available at https://go.dev/dl/.

After downloading a binary release, visit https://go.dev/doc/install
for installation instructions.

#### Install From Source

If a binary distribution is not available for your combination of
operating system and architecture, visit
https://go.dev/doc/install/source
for source installation instructions.

<!-- go.dev/issue/61542 -->
First, `Timer`s and `Ticker`s that are no longer referred to by the program
become eligible for garbage collection immediately, even if their
`Stop` methods have not been called.
Earlier versions of Go did not collect unstopped `Timer`s until after
they had fired and never collected unstopped `Ticker`s.
