+libcups v3.0.1 is bug fix release.  Changes include:
+
+- Updated the internal implementation of `ipp_t` to avoid issues on some
+  embedded platforms (Issue #141)
+- Updated `httpAddrLookup` to return a numeric address when the resolver
+  returns "localhost" for a non-loopback address.
+- Updated `cupsFileGetConf` and `cupsFilePutConf` to escape more characters.
+- Updated `cupsRasterReadHeader` to validate more of the page header values.
+- Updated `ippeveprinter` to support custom "printer-state-reasons" keyword
+  values (Issue #142)
+- Fixed a bug when the `ippFindXxx` and `ippSetXxx` functions were mixed
+  (Issue #138)
+- Fixed error handling in the low-level TLS read/write functions.
+
+Enjoy!
