New Features

• You can now disable the building of debug data using the new --gotenberg-build-debug-data flag (default: true)
  or the GOTENBERG_BUILD_DEBUG_DATA environment variable. This can significantly improve startup time in environments like Google Cloud Run.
  Thanks @​ChocoChipset for the contribution!

Bug Fixes

This release includes two bug fixes for the Chromium module:

1. A minor issue in a dependency was causing generated PDFs to be tagged by default. That’s no longer the case.
   Thanks to @​dani for the heads-up and @​kenshaw for the resolution!

2. The printBackground form field now works as expected.
   Thanks @​Welteam for reporting the issue!

Thanks @​ChocoChipset for the suggestion!

LibreOffice Optional Indexes Update

New form field updateIndexes (default true) for the route /forms/libreoffice/convert. Set its value to false if your PDF is missing links present in the original document.

v8.17.3: 8.17.3

Compare Source

Bug Fix

In Gotenberg 8.17.2 (amd64), a dependency was causing excessive error logs with the Chromium module. The issue has been fixed upstream, and this release includes that fix.

Thanks to @​lindeberg for the heads-up and @​kenshaw for the quick fix!

v8.17.0: 8.17.0

Compare Source

New Features

Configuration with Environment Variables

You can now configure your Gotenberg instances using environment variables. For example, instead of setting --api-port=3000, you can use API_PORT=3000.

Thank you, @​rojomisin, for the suggestion!

Debug Route

When enabled with --api-enable-debug-route (or API_ENABLE_DEBUG_ROUTE=true), the /debug endpoint returns formatted JSON detailing your Gotenberg instance's configuration (including flag values, architecture, etc.).

Thank you, @​nktnet1, for the suggestion!

Bug Fix

Due to a CI misconfiguration, the /version route in Gotenberg 8.16.0 was displaying an empty string. This issue has been fixed. Thanks to @​clee231 for the heads-up!

Chore

• Updates Chromium to version 133.0.6943.53 (except for arm64).
• Updates Go dependencies.

v8.16.0: 8.16.0

Compare Source

New Features

Flattening Annotations

Thanks to @​chakalov, this release brings a new multipart/form-data route for flattening PDFs:

POST /forms/pdfengines/flatten

This feature is also available to the following routes via a new form field flatten (boolean):

• /forms/libreoffice/convert
• /forms/pdfengines/merge
• /forms/pdfengines/split

Chromium Restart Strategy

The new default value for the --chromium-restart-after flag is 10, helping stabilizing the memory usage of your Gotenberg instances.

[!TIP]
Set this value to 0 to reset to the previous behavior.

Thanks @​HarryGogonis, @​michalschroeder and @​Fank for the help! See #​987 for more details.

New Log Field log_type

The logs have now a new field log_type to help differentiating entries (either application or access).

Dummy Root Route

Thanks to @​nktnet1, a new root route (e.g., /) prints a welcome message with a link to the documentation.

Faster CI / Latest Chromium Version for armhf

The releasing of a new Docker image of Gotenberg has been drastically reduced, from approximately 1 hour to less than 5 minutes, thanks to arm64 GitHub runners. This also allows for the latest Chromium version on the armhf variant.

Misc

[!CAUTION]
/version route is now behind the basic authentication if enabled.

Chore

• Updates Chromium to version 132.0.6834.110/160.

Thanks @​ps73, @​nodecentral, @​markitosgv, @​wjkoh!

Split Chromium PDFs

The multipart/form-data routes from the Chromium module also accepts the previous form fields for splitting the resulting PDF.

Split LibreOffice PDFs

In the same manner, the multipart/form-data route from the LibreOffice module accepts the previous form fields for splitting the resulting PDFs.

New Features

Select PDF Engines per Feature

You may now select PDF engines for each feature thanks to new flags:

• --pdfengines-merge-engines - Set the PDF engines and their order for the merge feature (default qpdf,pdfcpu,pdftk).
• --pdfengines-convert-engines - Set the PDF engines and their order for the convert feature (default libreoffice-pdfengine).
• --pdfengines-read-metadata-engines - Set the PDF engines and their order for the read metadata feature (default exiftool).
• --pdfengines-write-metadata-engines - Set the PDF engines and their order the write metadata feature (default exiftool).

⚠️ The flag --pdfengines-engines is deprecated.

Fail On Resource HTTP Status Codes (Chromium)

Like failOnHttpStatusCodes, the new failOnResourceHttpStatusCodes form field tells Gotenberg to return a 409 Conflict response if the HTTP status code from at least one resource is not acceptable.

Resource Network Errors (Chromium)

The new form field failOnResourceLoadingFailed tells Gotenberg to return a 409 Conflict if Chromium encounters any of the following network errors while attempting to load a resource:

• net::ERR_CONNECTION_CLOSED
• net::ERR_CONNECTION_RESET
• net::ERR_CONNECTION_REFUSED
• net::ERR_CONNECTION_ABORTED
• net::ERR_CONNECTION_FAILED
• net::ERR_NAME_NOT_RESOLVED
• net::ERR_INTERNET_DISCONNECTED
• net::ERR_ADDRESS_UNREACHABLE
• net::ERR_BLOCKED_BY_CLIENT
• net::ERR_BLOCKED_BY_RESPONSE
• net::ERR_FILE_NOT_FOUND

Chore

• Updates Chromium to version 130.0.6723.91 (except for armhf).
• Updates Go dependencies.

v8.12.0: 8.12.0

Compare Source

New Features

Bind IP

The new flag --api-bind-ip allows to set the IP address the API should bind to for incoming connections, instead of the default 0.0.0.0.

For instance: --api-bind-ip=127.0.0.1.

Thanks @​dani for the suggestion!

Scope Extra HTTP Headers (Chromium)

You can add an optional scope token to a header value to restrict its application using a regular expression.

For instance:

curl \
--request POST http://localhost:3000/forms/chromium/convert/url \
--form url=https://my.url \
--form-string 'extraHttpHeaders={"X-Scoped-Header":"value;scope=https?:\\/\\/([a-zA-Z0-9-]+\\.)*domain\\.com\\/.*"}' \
-o my.pdf

This new scope token is only processed by Gotenberg and is never sent with the header value.

Thanks @​forg002-ctrl and @​OsoianMarcel for the help!

pdfcpu CLI

In earlier versions of Gotenberg, we used the pdfcpu Golang library directly. However, there wasn't a clean way to terminate the process in case of a timeout, which could lead to resource leaks. We now rely on the pdfcpu CLI, allowing us to effectively handle timeouts, resulting in a more stable PDF engine.

Updates Go dependencies.
