## c-ares version 1.34.8 - July 7 2026
2+
3+
This is a bugfix release.
4+
5+
Bugfixes:
6+
* Revert "Mark parameters in callbacks as const" which shipped in 1.34.7.
7+
Changing the parameter types of the `ares_callback`, `ares_host_callback`,
8+
and `ares_nameinfo_callback` function pointer typedefs was an unintended
9+
API break: existing applications with the historical non-const callback
10+
signatures no longer compiled, particularly in C++ where function pointer
11+
types must match exactly. The read-only nature of the callback parameters
12+
is now documented instead.

30+
chains. Please see
