Fixed
- Traffic history: upgrading from 1.96 or earlier now keeps the traffic history on installs of any ordinary size. 1.97.0 cleared it on most installs with more than about a hundred interfaces, not only on very large ones as intended. History already cleared by 1.97.0 cannot be restored.
- Security: when a CVE is fixed separately on each RouterOS branch, the "fix in" version now matches the device's own branch. A device on 7.24.2 was pointed at 7.23.6 instead of 7.24.3.
