6.2.0 (2014-12-10)

- Bug #1005 "Security Report, LFI posting internal files externally abusing default parameter" was fixed. - Static methods serializeTCPDFtagParameters() and unserializeTCPDFtagParameters() were moved as non static to the main TCPDF class (see changes in example n. 49). - Deprecated methods were removed, please use the equivalents defined in other classes (i.e. TCPDF_STATIC and TCPDF_FONTS). - The constant K_TCPDF_CALLS_IN_HTML is now set by default to FALSE. - DLE, DLX and DLP page format was added. - Page format are now defined as a public property in TCPDF_STATIC.
