+## Php 5.4-7.0 Support Dropped
+
+As of mail-mime-parser 2.3.0, support for php 5.4, 5.5, 5.6 and 7.0 has been dropped.
+
 ## Removal Notice (since 2.0.0)
 
 `getContentResourceHandle`, `getTextResourceHandle`, and `getHtmlResourceHandle` have all been deprecated in 1.2.1 and removed in 2.0.0. fread() will only return a single byte of a multibyte char, and so will cause potentially unexpected results/warnings in some cases, and psr7 streams should be used instead. Note that `getBinaryContentResourceHandle` and `getResourceHandle` are still available.
