The public GitHub repository "pdf-issues" hosted by the PDF Association provides all developers a means of openly reporting errata against ISO PDF related standards for review and resolution by industry and ISO experts. All issues in ISO PDF related standards are important, from minor typos and formatting issues, to larger ambiguous, unclear or apparently contradictory statements. By reaching consensus on resolutions as an industry, PDF interoperability and implementation reliability will be improved.

The current set of resolved errata are presented as additions, deletions or editor notes to the published wording in the relevant ISO standard organized by clause number. GitHub Issue numbers and ISO status will appear as popup tooltips when hovering over changes or inline when printed and refer back to closed GitHub pdf-issues.

• If a small blue ISO logo is also shown , then that errata has been approved by both the PDF Association's appropriate TWG and the appropriate ISO working group responsible for PDF.
  • For ISO 32000-2:2020 (PDF 2.0), this means the resolution will be included in the forthcoming Amendment 1.
• If a small gray ISO logo is also shown , then that errata has been approved by the appropriate PDF Association technical working group and submitted to the appropriate ISO working group responsible and is waiting for approval.
  • For ISO 32000-2:2020 (PDF 2.0), these errata have been technically approved by ISO TC 171 SC 2 WG 8, but do not yet have an identified ISO document.
• If no ISO logo is shown then the errata has been resolved by the appropriate PDF Association technical working group but has not yet been submitted to ISO for ratification.

Due to ISO copyright, only minimal surrounding text from the relevant ISO standard is provided that is sufficient to locate precisely where the resolution is being applied.
