Thanks to ggregory.<br /> o IO-331:  BOMInputStream wrongly detects UTF-32LE_BOM files as UTF-16LE_BOM files in method getBOM(). Thanks to ggregory.<br /> o IO-327:  Add byteCountToDisplaySize(BigInteger). Thanks to ggregory.<br /> o IO-326:  Add new FileUtils.sizeOf[Directory] APIs to return BigInteger. Thanks to ggregory, kinow.<br /> o IO-325:  Add IOUtils.toByteArray methods to work with URL and URI. Thanks to raviprak.<br /> o IO-324:  Add missing Charset sister APIs to method that take a String charset name. Thanks to raviprak.<br /> <br /> <strong>Fixed Bugs:</strong><br /> o IO-336:  Yottabyte (YB) incorrectly defined in FileUtils. Thanks to rleavelle.<br /> o IO-279:  Tailer erroneously considers file as new. Thanks to Sergio Bossa, Chris Baron.<br /> o IO-335:  Tailer#readLines - incorrect CR handling.<br /> o IO-334:  FileUtils.toURLs throws NPE for null parameter; document the behavior.<br /> o IO-332:  Improve tailer's reading performance. Thanks to liangly.<br /> o IO-279:  Improve Tailer performance with buffered reads (see IO-332).<br /> o IO-329:  FileUtils.writeLines uses unbuffered IO. Thanks to tivv.<br /> o IO-319:  FileUtils.sizeOfDirectory follows symbolic links. Thanks to raviprak.</p>
