metric. Tracks the count of current leases held by etcd to aide in debugging.

### Fixed
- Fixed bug where pipelines would hang after a pipeline/v1.TCPStreamHandler is
ran with max_connections set greater than zero.

## [6.6.6] - 2022-02-16

### Added
- Added error type to GraphQL metrics; primarily should help track down the
source of slow  queries.

### Fixed
- When "strict: true" is configured in store/v1.PostgresConfig, the postgres
provider will try to connect to an unavailable postgres server forever, instead
of giving up after 3 tries and reverting to etcd.
- Strict mode now checks whether the current user has CREATE privilege within
the current schema, not within the current database. This is a more precise
expression of the privileges actually needed to create and upgrade a sensu
database.
- The postgres provider now respects context cancellation and fails immediately
when a user issues a termination signal.
- Fixes issue where metrics were not recorded when an error occurred. Among
other things this meant that when a deadline was exceeded the duration was not
collected.

- Queries for multiple entity states, when using PostgreSQL, have been made more
efficient.
- [Web] Starting in v6.6.3, for performance reasons, filtering of entities stops
after 500 matches. In addition, with v6.6.5 and moving forward, if more than
500 entities match the filter, the web UI will display a message suggesting
there are more than 500 relevant entities.
- [Web] Federated clusters will now query remote clusters in parallel.
- [Web] Improved performance of GraphQL queries to the local cluster.
- [Web] Reduced potential cluster load by no longer invoking GraphQL field
resolvers when the query deadline has already been reached.

### Fixed
- Fixed bug in postgres round robin scheduling where notification routing
could be delayed after BSM service components are created or updated.
- Fixed bug in postgres config watcher where bsmd was not re-enabled correctly
on update.

## [6.6.4] - 2022-01-25

### Fixed
- Fixed bugs in BSM and round robin scheduling. When postgres round robin
scheduling is enabled, users will no longer see missed check executions.
- Fixed a bug where sensu-backend would crash if postgresql was taken offline
and started up again.
- Fixed a bug where ephemeral backend entity rows would fill up the entities
table in postgresql.
- BSM event selectors can no longer select events outside the ServiceComponent
namespace.
- [Web] Added X-Frame-Options header to tell browsers the web application cannot
be loaded within an iframe; loaded in this manner, it can be susceptible to
tailored click jacking attacks.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options
- [Web] Added HSTS header if TLS has been configured; ensures the browser loads
the application and its requisite assets with a secure connection.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security
- [Web] Added X-Content-Type-Options: nosniff header to have browsers respect
the given Content-Type header when loading content referenced by a script tag.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options
- Fixed a bug where HTTP requests were not properly cancelled after a context
deadline (timeout) had been exceeded.
