Version 1.1.0 contains a number of improvements, both in the backend and SDK. All
changes are backwards compatible, but some features have been deprecated and will be
removed in version 2.0, see the last section of this changelog entry.

**Summary**

* The API spec has been bumped to version 1.1.0
* A new minor version of the SDK is available, which requires a minimum backend version
  of 1.1.0
* Upgrading should be straigh-forward - no manual interventions are needed.

**New features**

* [#1418] Expose ``Submission.isAuthenticated`` in the API
* [#1404] Added configuration options for required fields

  - Configure whether fields should be marked as required by default or not
  - Configure if an asterisk should be used for required fields or not

* [#565] Added support for DigiD/eHerkenning via OpenID Connect protocol
* [#1420] Links created by the form-builder now always open in a new window (by default)
* [#1358] Added support for Mutual TLS (mTLS) in service configuration - you can now
  upload client/server certificates and relate them to JSON/SOAP services.
* [#1495] Reworked admin interface to configure mTLS for SOAP services
* [#1436] Expose ``Form.submissionAllowed`` as public field in the API
* [#1441] Added submission-specific user logout endpoint to the API. This now clears the
  session for the particular form only, leaving other form session untouched. For
  authenticated staff users, this no longer logs you out from the admin interface. The
  existing endpoint is deprecated.
* [#1449] Added option to specify maximum number of files for file uploads
* [#1452] Added option to specify a validation regular-expression on telefone field
* [#1452] Added phone-number validators to API for extensive validation
* [#1313] Added option to auto redirect to selected auth backend
* [#1476] Added readonly option to BSN, date and postcode components
* [#1472] Improved logic validation error feedback in the form builder
* [#1482, #1510] Added bulk export and import of forms functionality to the admin interface
* [#1483] Added support for dark browser theme
* [#1471] Added support for DigiD Machtigen and eHerkenning Bewindvoering with OIDC
* [#1453] Added Formio specific file-upload endpoint, as it expects a particular
  response format for success/failure respones. The existing endpoint is deprecated.
* [#1540] Removed "API" and "layout" tabs for the content component.
* [#1544] Improved overview of different components in the logic rule editor.
* [#1541] Allow some NL Design System compatible custom CSS classes for the content
  component.
* [#1451] Completely overhauled "submission rendering". Submission rendering is used
  to generate the confirmation e-mails, PDFs, registration e-mails, exports...

  - You can now specify whether a component should be displayed in different modes
    (PDF, summary, confirmation e-mail)
  - Implemented sane defaults for configuration options
  - PDF / Confirmation e-mails / registration e-mails now have more structure,
    including form step titles
  - Container elements (fieldsets, columns, steps) are only rendered if they have
    visible content
  - Logic is now respected to determine which elements are visible or hidden
  - Added a CLI render mode for debug/testing purposes
  - Fixed page numbers being half-visible in the confirmation PDF

* [#1458] Submission registration attempts are now limited to a configurable upper
  bound. After this is reached, there will be no automatic retries anymore, but manual
  retries via the admin interface are still possible.
* [#1584] Use the original filename when downloading submission attachments
* [#1308] The admin interface now displays warnings and proper error messages if your
  session is about to expire or has expired. When the session is about to expire, you
  can extend it so you can keep working for longer times in the UI.

**Bugfixes**

All the bugfixes up to the ``1.0.8`` release are included.

* [#1422] Prevent update of custom keys on label changes for radio button components
  in the form builder
* [#1061] Fixed duplicate 'multiple' checkbox in email component options
* [#1480] Reset steps with data if they turn out to be not applicable
* [#1560] Fix prefill fields in columns not working (thanks @rbakels)
