Release notes

This document describes all the changes made to the Discovery API document, starting from its first released version.

6.0.0

New major version. Backward-incompatible changes:

  • Added obligatory information about host provider (#19).
  • Made admin-email element required.

Other changes:

  • Forbidden admin-email to be associated with any person.

Note, that at the moment, the Registry Service supports both major formats (5 and 6).

5.1.0

  • Added note about using company aliases as admin-email.
  • Imposed 1 to 1 communication in EWP. It is no longer possible to have more than one host and one hei in a manifest!

5.0.0

New major version. Backward-incompatible changes:

  • All manifest contents are now required to be enclosed in the <host> element.

  • The manifest MAY now contain any number of <host> elements (from zero to infinity). Previously, the manifest could be used to describe exactly one EWP Host. See this issue.

Other changes:

  • Updated example reflecting recent changes in the Registry API.

Note, that at the moment, the Registry Service supports both major formats (4 and 5).

4.1.1

  • Added notices about version 4.x.x being obsoleted by version 5.0.0.
  • Fixed some minor details in manifest-example.xml.

4.1.0

  • New optional element under <client-credentials-in-use>: <rsa-public-key>.
  • New optional <manifest> section: <server-credentials-in-use>.
  • Updated manifest-example.xml. Makes use of the newly introduced elements, and HTTP Signature authentication methods.

4.0.5

  • Updated manifest-example.xml. It now features Echo API 2.0.0, which in turn makes use of the new Version 2 of Authentication and Security specification.

4.0.4

  • Use a bit more explicit wording in different parts of the specification.

4.0.3

  • Just updated some links (after splitting the Architecture and Security document).

4.0.2

  • minOccurs and maxOccurs are now provided explicitly (why?).

4.0.1

  • More details were added about manifest-entry.xsd files.
  • Some examples were added describing scenarios when one might want to split his manifest file into a couple of smaller ones.

4.0.0

  • <apis-implemented> and <hei> elements were moved to the Registry API's XML namespace. Thanks to this change, the Registry's catalogue won't need to reuse elements from Discovery API's XML namespace (which is a good thing, because the latter one is more likely to change in a backward-incompatible manner).

  • The deprecated fingerprint attribute of the <certificate> element was removed.

  • For consistency, Discovery API's manifest entry has been moved to a separate namespace (all other APIs currently keep it in a separate namespace too).

  • As with all major version changes, XML namespace identifiers were changed (stable-v3 was replaced with stable-v4).

3.2.0

  • fingerprint attribute of the <certificate> element has been marked as deprecated (to be removed in a future major release). It's length has been also corrected (SHA-256 hex digests have 64 characters, not 40).

  • Minor changes to the example manifest file (updated client certificate).

3.1.0

  • Unknown API entries are no longer strictly validated (more information).

  • <dev-email> and <dev-notes> elements were renamed to <admin-email> and <admin-notes> respectively (more information).

3.0.0

Backward-incompatible changes:

  • Definitions of <echo> and <registry> API entries have been removed from the manifest's XML namespace. From now on, each API will be described in its own manifest-entry.xsd XML namespace (so that its documentation will be present only in its own repository). See this issue for rationale.

  • The above change would render <dev-email> and <dev-notes> elements to be duplicated in two separate namespaces, so - to keep it clean - they were moved to the common-types namespace.

2.0.0

Backward-incompatible changes:

  • The <client-certificates-in-use> element has been renamed to <client-credentials-in-use>.

  • The <common-name> element was removed. Click here for details.

  • A single EWP Host is now allowed to serve multiple versions of a single API. Elements in <apis-implemented> are now maxOccurs="unbounded". Details and reasoning can be found here.

  • EWP Hosts are now required to keep track of SCHAC ID changes (they must publish previous SCHAC IDs in the manifest file). Details and reasoning can be found here.

  • SHA-1 hashes replaced with SHA-256 (reasoning).

Other changes:

  • The ApiEntry/dev-notes element was missing a type (MultilineString was added).

1.0.1

1.0.0

Initial release. Reviewed here and initially accepted during the meeting on the 5th of February 2016.
