> Hello,
>
> I am happy to announce release 0.25.0 of Hawkular Metrics. This release is
> anchored by general stability improvements and enhanced query capabilities
> for the external metrics alerter.
>
> Here is a list of major changes:
>
>    - *External Metrics Alerter - Enhancements*
>       - Both syntax and query capabilities have been revamped to allow
>       defining conditions using flexible expressions with embedded stats queries
>       - The ExternalCondition expression is now JSON and has support for
>       the new tag query language
>       - The full documentation about this feature can be found in the Alerting
>       section
>       <http://www.hawkular.org/hawkular-metrics/docs/user-guide/#_alerting>
>       of the user guide
>       <http://www.hawkular.org/hawkular-metrics/docs/user-guide/>
>       - For more details please see: HWKMETRICS-566
>       <https://issues.jboss.org/browse/HWKMETRICS-566> and Pull Request
>       727 <https://github.com/hawkular/hawkular-metrics/pull/727>
>    - *Dropwizard-Metrics - Merged*
>       - The Dropwizard-Metrics reporter
>       <https://github.com/hawkular/hawkular-dropwizard-reporter> has been
>       merged into the Metrics repository in clients/dropwizard
>       <https://github.com/hawkular/hawkular-metrics/tree/44677cc5d6267e738ea51bdd9a37be062ca1b8c2/clients/dropwizard>
>       module
>       - The old repository
>       <https://github.com/hawkular/hawkular-dropwizard-reporter> is
>       decommissioned, all new development will happen in the Metrics project
>       - This was done to simplify the compatibility matrix between the
>       reporter and Hawkular Metrics REST API; going forward they will have
>       identical versions. Furthermore, the compatibility is now tested via
>       continuous integration tests.
>       - Please use the new maven artifact hawkular-dropwizard-reporter
>       <http://origin-repository.jboss.org/nexus/content/repositories/public/org/hawkular/metrics/hawkular-dropwizard-reporter/0.25.0.Final/>
>       - For more details please see: HWKMETRICS-585
>       <https://issues.jboss.org/browse/HWKMETRICS-585>
>    - *Tag Query Language - Enhancements*
>       - The tag query language now supports the dot character in the tag
>       name. The list of allowed characters is *a-zA-Z_0-9.*
>       - The query language allows regex matching for tag values but not
>       tag names
>       - This allows translating JSON-like tag structures into Hawkular
>       Metrics tags and query using the new tag query language
>       - For example, a tag structure like [tag.subtag1: value1,
>       tag.subtag2.subsubtag1: value2] is now queriable via the tag query
>       language with queries like tag.subtag1 = value1 or
>       tag.subtag2.subsubtag1
>       - For more details please see: HWKMETRICS-611
>       <https://issues.jboss.org/browse/HWKMETRICS-611>
>    - *REST API - Request Logging*
>       - It is now possible to enable detailed logging for all REST API
>       requests
>       - Two properties have been added to enable this features:
>       hawkular.metrics.request.logging.level to enable logging for all
>       read requests and hawkular.metrics.request.logging.level.writes to
>       enable logging for write requests
>       - By default this feature is disabled, to enable just set the log
>       level via each property
>       - For more details please see: HWKMETRICS-589
>       <https://issues.jboss.org/browse/HWKMETRICS-589>
>       - Here is a sample log:
>
> INFO  [org.hawkular.metrics.api.jaxrs.util.RequestLoggingFilter] (default task-49)
> REST API request:
