         Flex-algo extension for show isis topology.
       2020-10-27
         Add a new type Isis-flex-algo-metric for flex-algo metrics and change the metric-type leaf in ISIS-SH-FLEX-ALGO-AREA to use it.
       2020-10-20
         Change in Yang tool corrected strings repair-s-rv6* to repair-srv6*, end-xsid* to end-x-sid*, and is-s-rv6 to is-srv6. Changed avg-dela-rawy to avg-delay-raw to fix misspelling via CSCvu63930. Changed SRv6 function-type to sid-behavior, uint32_t to mgmt_srv6_sid_fmt, and num-sid to num-sids for consistency and to comply with current IETF ISIS SRv6 draft via CSCvu06764.";
