-- Support deserializing message fragment without interchange #137
-- deserialize Functional group headers and trailers into a separate class #138
-- Revisited Element List deserialization and serialization #121
-- Fixed paths with wildcard fragments (segment and element) now serialize fine.
-- Fixed writer serializing boolean values #141.
-- Fixed EdiSerializer bug when using Serialize overload that passes a plain `TextWriter` the internal EdiTextWriter was never closed thus not autocompleteing/terminating the current active structure #142.
-- Fixed EdiReader when empty segment was found without segment name delimiter #152.
-- Introduced new `SuppressBadEscapeSequenceErrors` option on the serializer. it is used to suppress the exception error thrown when a malformed escape sequence is encountered #157.
-- Rolledback v1.9.10 `EscapeCharacters` change #160.
-- Introduced new `EscapeDecimalMarkInText`. It is used by the EdiTextWriter to escape the decimal mark character inside text values #160.
