- Fix: Fixed a bug about pagination problem due to missing ErrorCode with details in the case of queries with forwarding to context providers. (Issue #945)
- Fix: Taking into account the pagination limit before adding "potential" entities to be queried in CPrs. (Issue #945)
- Fix: Add multiservice flag for the default configuration in the RPM. (Issue #964)

- Add: New CLI parameter for the mutex policy: -reqMutexPolicy (Issue #910)
- Add: Measuring the accumulated time waiting for the DB semaphores.

- Fix: using proper GJSON for location.coords entities information (Issue #415)
- Fix: attribute storing in DB (from vector to keymap) to enable CB Active/Active architectures. As a consecuence of this, '.' in the name of attributes is now stored as
'=' in the key (as MongoDB doesn't allow to use '.' for keys). This is transparant from the point of view of the user, given that '=' is a forbidden character in
the external API (Issue #878)
- Fix: simplifying 'GET /v1/contextTypes' and 'GET /v1/contextTypes/<entityType>' operations, removing attribute types (no longer used as attribute identification since 0.17.0). As

To change this timeout, a new CLI option '-httpTimeout' has been added to the broker.
- Fix: Changed the name, type and unit of the CLI option '-timeout'.
New name: '-dbTimeout',
New type: integer (was a floating point number)
New unit: milliseconds (was seconds, but decimals were allowed as it was a floating point number)
- Add: Updates of ngsi9 subscriptions now also support the URI parameter notifyFormat
0.20.0 (March 31st, 2015)

in both payload and URL, as long as the values coincide.
- Fix: A few more of the 'responses without entityId::type filled in' found and fixed (Issue #585)
- Fix: The convenience operations "/v1/contextAttributes/{entity::id}/attributes" now share implementation with
convenience operations "/v1/contextAttributes/{entity::id}" and are thus 100% identical.
- Fix: The convenience operation "PUT /v1/contextAttributes/{entity::id}/attributes/{attribute::name}" had a bug
about the metadata in the update, this error has been fixed.
- Fix: A registerContext request that uses associations must specify "attributeAssociations" instead of "attributes" to be consistent with DiscoveContextAvailability messages (Issue #823).
- Fix: Fixed a bug that made the broker crash when compound attribute values were used in convenience operations.
- Fix: Implemented URI-parameter 'notifyFormat=XML/JSON' for NGSI9 subscriptions.

- Add: New name for URI param 'attributesFormat': 'attributeFormat' (better English).
The old name will be supported as well. (Issue #633)

- Add: "/" is used as implicit service path for entities. (Issue #646)
- Add: Queries without Fiware-ServicePath are resolved on "/#" implicitly (i.e. all the paths). (Issue #646)
