### LWG motion 19

82+
Did not add the macro `__cpp_lib_atomic_ref`.
83+
This macro already existed with the specified value.
84+
85+
Did not change the value of the `__cpp_lib_chrono` macro.
86+
The requested new value of this macro (`201803L`)
87+
is actually lower than the current value
88+
(`201907L`, not `201611L` as listed in [P1902R1](http://wg21.link/p1902r1)).
89+
The chair of SG10 has confirmed that the request to change this macro's value
90+
is an error. The pre-existing, higher value is retained.
91+
92+
Did not change the value of the `__cpp_lib_ranges` macro.
93+
The requested new value of this macro (`201907L`)
94+
is lower than the value `201911L` introduced by
95+
[P1716R3](http://wg21.link/po1716r3) (LWG motion 6).

## Feature test macros

99+
The following feature test macro changes were made
100+
after consultation with SG10,
101+
in addition to the feature test macro changes
102+
requested by motions:
103+
82104
The feature test macro `__cpp_nontype_template_parameter_class` has been removed
83105
to indicate that the feature added by [P0732R2](http://wg21.link/p0732r2)
84106
is no longer present in the same form.
