## [0.6.0] - 2016-09-13
### Added
* New style Diaspora Magic Envelope support. The magic envelope can be created using the class `federation.protocols.diaspora.magic_envelope.MagicEnvelope`. By default this will not wrap the payload message in `<XML><post></post></XML>`. To provide that functionality the class should be initialized with `wrap_payload=True`. No changes are made to the protocol send methods yet, if you need this new magic envelope you can initialize and render it directly.
### Changed
* Deprecate receiving user `key` attribute for Diaspora protocol. Instead correct attribute is now `private_key` for any user passed to `federation.inbound.handle_receive`. We already use `private_key` in the message creation code so this is just to unify the user related required attributes.
* DEPRECATION: There is a fallback with `key` for user objects in the receiving payload part of the Diaspora protocol until 0.8.0.
### Fixes
* Loosen up hCard selectors when parsing profile from hCard document in `federation.utils.diaspora.parse_profile_from_hcard`. The selectors now match Diaspora upcoming federation documentation.
## [0.5.0] - 2016-09-05
### Breaking changes
- `federation.outbound.handle_create_payload` parameter `to_user` is now optional. Public posts don't need a recipient. This also affects Diaspora protocol `build_send` method where the change is reflected similarly. [#43](https://github.com/jaywink/social-federation/pull/43)
- In practise this means the signature has changed for `handle_create_payload` and `build_send` from **`from_user, to_user, entity`** to **`entity, from_user, to_user=None`**.
### Added
- `Post.provider_display_name` is now supported in the entity outbound/inbound mappers. [#44](https://github.com/jaywink/social-federation/pull/44)
- Add utility method `federation.utils.network.send_document` which is just a wrapper around `requests.post`. User agent will be added to the headers and exceptions will be silently captured and returned instead. [#45](https://github.com/jaywink/social-federation/pull/45)
- Add Diaspora entity utility `federation.entities.diaspora.utils.get_full_xml_representation`. Renders the entity XML document and wraps it in `<XML><post>...</post></XML>`. [#46](https://github.com/jaywink/social-federation/pull/46)
## [0.4.1] - 2016-09-04
### Fixes
- Don't quote/encode `Protocol.build_send` payload. It was doing it wrongly in the first place and also it's not necessary since Diaspora 0.6 protocol changes. [#41](https://github.com/jaywink/social-federation/pull/41)
- Fix identification of Diaspora protocol messages. This was not working in the case that the attributes in the tag were in different order. [#41](https://github.com/jaywink/social-federation/pull/41)
## [0.4.0] - 2016-07-24
### Breaking changes
- While in early stages, doing some renaming of modules to suit the longer term. `federation.controllers` has been split into two, `federation.outbound` and `federation.inbound`. The following methods have new import locations:
* `federation.controllers.handle_receive` -> `federation.inbound.handle_receive`
* `federation.controllers.handle_create_payload` -> `federation.outbound.handle_create_payload`
- Class `federation.hostmeta.generators.DiasporaHCard` now requires `guid`, `public_key` and `username` for initialization. Leaving these out was a mistake in the initial implementation. Diaspora has these in at least 0.6 development branch.
### Added
- `Relationship` base entity which represents relationships between two handles. Types can be following, sharing, ignoring and blocking. The Diaspora counterpart, `DiasporaRequest`, which represents a sharing/following request is outwards a single entity, but incoming a double entity, handled by creating both a sharing and following version of the relationship.
- `Profile` base entity and Diaspora counterpart `DiasporaProfile`. Represents a user profile.
- `federation.utils.network.fetch_document` utility function to fetch a remote document. Returns document, status code and possible exception. Takes either `url` or a `host` + `path` combination. With `host`, https is first tried and optionally fall back to http.
- Utility methods to retrieve Diaspora user discovery related documents. These include the host-meta, webfinger and hCard documents. The utility methods are in `federation.utils.diaspora`.
- Utility to fetch remote profile, `federation.fetchers.retrieve_remote_profile`. Currently always uses Diaspora protocol. Returns a `Profile` entity.
### Changed
- Unlock most of the direct dependencies to a certain version range. Unlock all of test requirements to any version.
- Entities passed to `federation.controllers.handle_create_payload` are now converted from the base entity types (Post, Comment, Reaction, etc) to Diaspora entity types (DiasporaPost, DiasporaComment, DiasporaLike, etc). This ensures actual payload generation has the correct methods available (for example `to_xml`) whatever entity is passed in.
### Fixes
- Fix fetching sender handle from Diaspora protocol private messages. As it is not contained in the header, it needs to be read from the message content itself.
- Fix various issues with `DiasporaHCard` template after comparing to some real world hCard templates from real pods. Old version was based on documentation in Diaspora project wiki.
## [0.3.2] - 2016-05-09
### Changed
- Test factories and other test files are now included in the package installation. Factories can be useful when creating project tests.
- Bump allowed `lxml` to 3.6.0
- Bump allowed `python-dateutil` to 2.5.3
### Fixes
- Don't raise on Post.tags if Post.raw_content is None
## [0.3.1] - 2016-04-13
### Added
- Support for generating `.well-known/nodeinfo` document, which was forgotten from the 0.3.0 release. Method `federation.hostmeta.generators.get_nodeinfo_well_known_document` does this task. It requires an `url` which should be the full base url of the host. Optionally `document_path` can be specified, but it is optional and defaults to the one in the NodeInfo spec.
## [0.3.0] - 2016-04-13
### Added
- Support for generating [NodeInfo](http://nodeinfo.diaspora.software) documents using the generator `federation.hostmeta.generators.NodeInfo`. Strict validation is skipped by default, but can be enabled by passing in `raise_on_validate` to the `NodeInfo` class. By default a warning will be generated on documents that don't conform with the strict NodeInfo values. This can be disabled by passing in `skip_validate` to the class.
## [0.2.0] - 2016-04-09
### Backwards incompatible changes
- Any implementations using the Diaspora protocol and `Post` entities must now use `DiasporaPost` instead. See "Changed" below.
### Added
- Support for using `validate_field()` methods for entity fields and checking missing fields against `_required`. To use this validation, `validate()` must specifically be called for the entity instance.
- Base entities `Comment` and `Reaction` which subclass the new `ParticipationMixin`.
- Diaspora entity `DiasporaComment`, a variant of `Comment`.
- Diaspora entity `DiasporaLike`, a variant of `Reaction` with the `reaction = "like"` default.
### Changed
- Refactored Diaspora XML generators into the Diaspora entities themselves. This introduces Diaspora versions of the base entities called `DiasporaPost`, `DiasporaComment` and `DiasporaLike`. **Any implementations using the Diaspora protocol and `Post` entities must now use `DiasporaPost` instead.**
### Fixes
- Entities which don't specifically get passed a `created_at` now get correct current time in `created_at` instead of always having the time part as `00:00`.
## [0.1.1] - 2016-04-03
### Initial package release
Supports well Post type object receiving over Diaspora protocol.
Untested support for crafting outgoing protocol messages.
