Title: I just discovered that Adobe took down the PDF 1.7 specification from their site. It&#x27;s used to be hosted at [1] and I can&#x27;t find a replacement. Of course this doesn&#x27;t mean that the specification can&#x27;t be acquired freely from elsewhere [2, 3], but it&#x27;s unfortunate if the authoritative source is down. Hopefully it is a mistake though and it will be back up.<p>[1] http:&#x2F;&#x2F;www.adobe.com&#x2F;content&#x2F;dam&#x2F;acom&#x2F;en&#x2F;devnet&#x2F;pdf&#x2F;pdfs&#x2F;PDF32000_2008.pdf<p>[2] https:&#x2F;&#x2F;christianhaider.de&#x2F;dokuwiki&#x2F;lib&#x2F;exe&#x2F;fetch.php?media=pdf:pdf32000_2008.pdf<p>[3] https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20220309040754if_&#x2F;https:&#x2F;&#x2F;www.adobe.com&#x2F;content&#x2F;dam&#x2F;acom&#x2F;en&#x2F;devnet&#x2F;pdf&#x2F;pdfs&#x2F;PDF32000_2008.pdf
