Breaking Changes
In loopd.conf file maxlsatcost and maxlsatfee were renamed to maxl402cost
and maxl402fee accordingly. Old versions of the options are still recognized
for backward compatibility, but a deprecation warning is printed. Users are
encouraged to change the options to new names if they have been changed locally.
The path in looprpc "/v1/lsat/tokens" was renamed to "/v1/l402/tokens" and
the corresponding method was renamed from GetLsatTokens to GetL402Tokens.
New loop binary won't work with old loopd, because loop listauth is now
calling GetL402Tokens method, which does not exist in previous loopd binary.
Old loop binary works with new loopd, since loopd provides a wrapper for
GetLsatTokens which calls GetL402Tokens; the wrapper logs a warning and
it will be removed in a couple of releases. HTTP endpoint "/v1/l402/tokens" is
now an additional binding for API "/v1/lsat/tokens", so it still works.
