This 1.3 release fixes a 500 http error code when accessing linux-log-parser
tests, also improving its log detection, including `WARNINGS`.

The release also fixes some minor issues related to docker setup, among
other new features and fixes that you can see in the full log below:

* core:
* test_history: handle tests with no metadata
* plugins: linux_log_parser: improve kernel log parsing
* frontend: reduce query time fetching metric names
* misc:
* debug: add django debug toolbar
* doc: add firewall note when running on docker
* Dockerfile: ignore version constraints from requirements.txt

This 1.2 release fixes a couple of performance issues when fetching testjobs
from backends and when using the REST api, among other small fixes.

It stops ignoring duplicated tests for same environments and test suites
when calculating build summary (e.g. number of passing and failing tests).
Instead, use partial summaries already calculated for test runs.

We tweaked the backend code that fetches tests before calculating
regressions and fixes. If a build had a significant high number of test runs
it would make comparison much slower. So we avoid querying all test runs at
once when running `TestComparison`.

There were changes in the backend code of the REST api that reduced the number
of trips to db, making some endpoints load faster.

* core:
* comparison: remove the use of iterator over tests
