Both types have been added to the enumeration com.openexchange.mail.search.ComparisonType as values LESS_EQUALS and GREATER_EQUALS. They map to their according javax.mail types javax.mail.search.ComparisonTerm.LE and javax.mail.search.ComparisonTerm.GE. The new types are used in:

- com.openexchange.mail.search.ReceivedDateTerm
- com.openexchange.mail.search.SentDateTerm
- com.openexchange.mail.search.SizeTerm

MAL implementations whose search-methods operate on com.openexchange.mail.search.SearchTerm need to support those new types. They are currently used by the new in-app search (via Find API).
