**Bug fixes**:

- Missing files when `pip install`ing (Materials-Consortia#252) via Materials-Consortia#253 by @shyamd.

v0.8.0

**New features**:
- Resource adapter. Intended for use in clients. It mimicks the
`EntryResource` class in models, while also open the possibility to
convert an OPTIMADE resource to other well-known formats for the
specific resource (e.g., ASE Atoms or CIF file for structures). See more
info in the commit descriptions for 9bedc78 (Materials-Consortia#241, @CasperWA with
testing by @ml-evs)
- Enable passing an URI, when using MongoDB (Materials-Consortia#150, @shyamd)
- Enable filtering on entry resource `relationships` for the MongoDB
transformer (Materials-Consortia#234, @ml-evs)
- Concept of `LENGTH` aliases, where one may link a resource property's
size/length to another resource property (Materials-Consortia#222, @ml-evs)
- Move to `pydantic`'s `BaseSettings` for the server configuration
details (Materials-Consortia#226, @shyamd)
- Use [Dependabot](https://dependabot.com/) to keep track of
dependencies (@CasperWA)

**Updates**:
- Remove query constraints for the `/links`-endpoint, making it able to
handle a query on the same level as an entry resource endpoint (Materials-Consortia#244,
@CasperWA)
- Add handling of the `filter`'s `LENGTH` operator when using the
MongoDB transformer (Materials-Consortia#222, @ml-evs)
- Scrape all `filter` query examples from [the OPTIMADE API
specification](https://github.com/Materials-Consortia/OPTIMADE/blob/develop/optimade.rst)
for testing (Materials-Consortia#227, @ml-evs)
- Use [new OPTIMADE
capitalization](Materials-Consortia/OPTIMADE#193)
throughout the repository (Materials-Consortia#233, @ml-evs)
- README now reflects the extraction of the GH Action for validation
into a [different
repository](https://github.com/Materials-Consortia/optimade-validator-action)
(Materials-Consortia#231, @ml-evs)

**Bug fixes**:
- Release to PyPI _only_ when a GitHub release is published (Materials-Consortia#235, Materials-Consortia#236,
@shyamd, @CasperWA)
- Several minor fixes related to the changes included in this update
already (@ml-evs, @CasperWA, @shyamd)

Merge pull request Materials-Consortia#235 from shyamd/fix-rls-on-tag

Fix github actions for non-release tags

Bumped version to 0.7.0

v0.6.0

**New features**:
- GitHub Action validator that runs `optimade_validator` for a locally
running OPTiMaDe server (Materials-Consortia#191, @CasperWA, tested by @ml-evs)
- Support filter queries for `HAS ALL`, `HAS ANY` and `HAS ONLY` and
value lists on MongoDB backends (Materials-Consortia#173, @ml-evs)
  Note: `OPERATOR` use in value lists are still _not_ supported.
- Debug mode. Start the server in debug mode to enable `debug` log-level
in `uvicorn` and get a full Python traceback in the JSON response (Materials-Consortia#190,
@CasperWA)
- Add testing of mandatory `filter` queries to `optimade_validator`
(Materials-Consortia#205, @ml-evs)

**Updates**:
- Allow Cross-Origin requests from anywhere (`*`), i.e., enable CORS for
both servers (Materials-Consortia#194, @CasperWA)
- Updates to models (correct misspelling, more transparent model class
naming, streamline models with respect to python class inheritance,
update field descriptions) (Materials-Consortia#195, @CasperWA)
- API change: Rename `optimade.models.toplevel.py` to
`optimade.models.responses.py` (Materials-Consortia#195, @CasperWA)
- Update dependencies to newest versions (as of 02.03.2020) (Materials-Consortia#202, Materials-Consortia#196,
@CasperWA)
- Move imports from `starlette` to `fastapi`, where possible (Materials-Consortia#202,
@ml-evs)
- Remove custom middleware to redirect slashed URLs in favor of
`starlette` implementation (Materials-Consortia#202, @ml-evs)
- CI tests are now performed with a real MongoDB in the backend. CI
tests are also performed with a `mongomock` backend for the tests in
`server/test_middleware.py`, `server/test_server_validation.py`, and
`server/test_config.py` (Materials-Consortia#196, @ml-evs, additional testing by @CasperWA
)
- Remove `/optimade` from base URLs. This was especially important for
the OpenAPI schema (Materials-Consortia#201, Materials-Consortia#216, @CasperWA, @ml-evs)
- Check integrity of query part of the raw URL using a custom middleware
(Materials-Consortia#209, @CasperWA)
- New `optimade/server/exceptions.py` to contain custom
`HttpException`s, moved `BadRequest` here (Materials-Consortia#209, @CasperWA)
- Pattern and regex testing for `data.available_api_versions` parts in
`/info` endpoint and fix tests for the same (Materials-Consortia#211, @CasperWA)
- Restructure import of test data for regular server (Materials-Consortia#212, @shyamd)

**Bug fixes**:
- New retrieval URL for Materials-Consortia's list of providers (Materials-Consortia#187,
@CasperWA)
- Skip local `HAS ONLY` tests with a `mongomock` backend, since v3.19.0
does not support these (Materials-Consortia#206, @ml-evs)
- Resource ID's can now contain slashes (`/`) (Materials-Consortia#183, @ml-evs, @CasperWA)
- Remove _valid_ version part of base URL in `meta.query.representation`
(Materials-Consortia#201, @CasperWA)
