+<a name="4.1.1"></a>
+## [4.1.1](https://github.com/w3c/epubcheck/compare/v4.1.0...v4.1.1) (2019-01-22)
+
+This is a maintenance release of EPUBCheck, the conformance validator for EPUB publications. It mostly consists of bug fixes and updated localized messages.
+
+This release was made by the DAISY Consortium, for the W3C.
+
+Many thanks to the various people who contributed to this release, notably the team of translators including Elisa Molinari, Emiliano Molina, Gregorio Pellegrino, Masayoshi Takahashi, Merijn de Haen, Thiago de Oliveira Pereira, Vincent Gros, Woongyoung Park… and especially Tobias Fischer, who has been coordinating the translation contributions!
+
+**Note:** this release is part of the 4.1.x stable stream, which checks conformance to the EPUB 3.0.1 family of specifications. It does _not_ include support for the newer EPUB 3.2 specifications. For a preview of EPUB 3.2 conformance checking, feel free to try the latest release in the 4.2.x beta stream (currently [v4.2.0-alpha-1](https://github.com/w3c/epubcheck/releases/tag/v4.2.0-alpha-1))!

+EPUBCheck
+=========
+
+This folder contains the distribution of the EPUBCheck project.
+
+EPUBCheck is a tool to validate the conformance of EPUB publications against
+the EPUB specifications. EPUBCheck can be run as a standalone command-line tool
+or used as a Java library.
+
+EPUBCheck is open source software, maintained by the DAISY Consortium on behalf
+of the W3C.
+
+EPUBCheck project home: https://github.com/w3c/epubcheck
+
+
+RUNNING
+-------
+
+To run the tool you need a Java runtime (1.7 or above).
+Any Operating System should do.
+
+Run it from the command line:
+
+>  java -jar epubcheck.jar file.epub
+
+All detected errors are simply printed to the standard error stream.
+
+Print the commandline help with the --help argument:
+
+>  java -jar epubcheck.jar --help
+
+
+USING AS A LIBRARY
+------------------
+
+You can also use EPUBCheck as a library in your Java application. EPUBCheck
+public interfaces can be found in the `com.adobe.epubcheck.api` package.
+EPUBCheck class can be used to instantiate a validation engine. Use one of its
+constructors and then call validate() method. Report is an interface that you
+can implement to get a list of the errors and warnings reported by the
+validation engine (instead of the error list being printed out).
+
+

+Most of the EPUBCheck functionality comes from the schema validation tool Jing
+and schemas that were developed by IDPF and DAISY. Initial EPUBCheck development
+was largely done at Adobe Systems. EPUBCheck 4.0 was largely developed by
+DAISY and Barnes & Noble.
