the log of notification about LE is very important to help us to see the process of LE:e.g.
the current log have some problems:
1:don't use the placeholder(other:+),don't in the style of k:v（antiman）
2.the properties in the logs are very messed(no group by,no order), not easy to read.
3.the value about version is HEX which don't have the 0x prefix.
