<a id="bug-fixes">

### Bug fixes

* Restricted resources loaded during conversion

  Submitted content could cause the converter to read files from its own container filesystem and include them in the generated PDF. Any caller authorized to request a conversion could trigger this; access was limited to files readable by the non-root converter process.

  Resources must now be served over HTTP(S); use the `base_url` option for relative paths.

  The issue was found by Simeon Krastev and reported by [neoshare AG](https://neoshare.de/). Thank you!

<a id="features">

### Features

\*\*\* Note: \*\*\*\
The `/v2/convert/html-pdf` endpoint has been introduced with this version.\
The `v2` provides a number of new features and optimizations to the Export to PDF feature. All changes mentioned in the changelog apply to the `v2` version.\
In case of any problem or regression, we encourage you to use the previous version and report the discovered problems through the support channel.

* Added header and footer variants for first, odd, and even pages

  Header and footer variants now support images as well.

* Added support for custom page sizes

  The page size can be set to a predefined format or a custom width/height object.

* Added mirror margins

  This allows book-like margins where left and right margins swap between pages.

* Added metadata, password protection, and digital signatures

  You can now set PDF metadata, protect documents with a password, and sign PDFs using a PKCS 12 certificate.

* Enabled PDF compression by default

  Compression can be disabled via `config.disable_compression`.

* Enabled stream processing by default

  This allows for larger payloads compared to v1.

* Reworked request payload shape for v2

  The API is now unified with Export to Word v2, with features grouped by purpose for a tidier, more structured payload. See the migration guide in `/v2/convert/docs#section/Export-to-PDF-(v2)/Migration-guide-from-v1-to-v2`.
