# Stork 0.14.0, December 9th, 2020, Release Notes

Welcome to the Stork 0.14.0 release. This is a development release of
the Stork dashboard.

The changes introduced in this version are:

* **Large configuration handling**: Stork 0.14 is now much better suited
for handling large configurations, e.g. with several thousand subnets.
The process of adding new subnets has been greatly streamlined and now
takes much less time. Subnets are now indexed (#421). Another problem
solved was that the Stork server triggered the periodic configuration
pull too early. If the initial update took a long time, the first
periodic renewal kicked off before the initial update was complete. This
race condition is fixed (#446). Furthermore, Stork's periodic
configuration pull is now smarter. It calculates a hash and is able to
detect a configuration change, bypassing unnecessary processing in the
very likely case of the configuration not changing (#460).

* **Reconfigure events**: Stork now records the reconfiguration events
detected in Kea. The information about the user who authorized the
change is not logged. This information may be added in a future Stork
release (#353, #460).

* **Documentation updates**: Grafana and Prometheus integration is now
documented properly, with examples (#451). A note has been added about
missing lease statistics and how to fix the problem, by loading
stat_cmds hook for Kea (#433).

* **Events filtering**: Earlier Stork versions showed all events on
various pages. This was confusing, as events related to machine A were
also presented when viewing machine B. Right now the widgets show only
relevant events (#429).

* **Tools update**: The Go compiler has been updated to 1.15. This is
not a user visible change. Nevertheless, it's worth mentioning that the
Stork team keeps up the pace with the latest developments in the
industry. We're also working on the update to Angular 10 (#457).

* **Test improvements**: The Stork team takes testing and other QA
practices very seriously. We've spent a significant amount of time
improving system tests (#434), stabilizing Selenium tests for our UI
interface (#453) and made other UI test improvements (#435).

## Release Model

Stork has monthly development releases, with some exceptions.

We encourage users to test the development releases and report back
their findings on the stork-users mailing list, available at
https://lists.isc.org/mailman/listinfo/stork-users.

ISC provides documentation in the Stork Administrator Reference Manual.
It is available on ReadTheDocs.io at
https://stork.readthedocs.io/en/latest/, and in source form in the docs/
directory.

We ask users of this software to please let us know how it worked for
you and what operating system you tested on. Feel free to share your
feedback on the stork-users mailing list
(https://lists.isc.org/mailman/listinfo/stork-users). We would also like
to hear whether the documentation is adequate and accurate. Please open
tickets in the Stork GitLab project for bugs, documentation omissions
and errors, and enhancement requests. We want to hear from you even if
everything worked.

## Support
Professional support for Stork will become available once it reaches the
1.0 milestone. Existing ISC customers that consider themselves *very*
early adopters may get involved in the development process, including
roadmap, features planning, and early testing, but the software maturity
level does not constitute a typical professional service before the 1.0
milestone.

Free best-effort support is provided by our user community via a mailing
list. Information on all public email lists is available at
https://www.isc.org/mailinglists/. If you have any comments or questions
about working with Stork, please share them to the stork-users list
(https://lists.isc.org/mailman/listinfo/stork-users). Bugs and feature
requests may be submitted via GitLab at
https://gitlab.isc.org/isc-projects/stork/issues.

## Changes
The following summarizes changes and important upgrades since the Stork
0.13.0 release.

```
* 121 [func] marcin

    Events received over SSE and presented on various Stork pages are
    now filtered and only the events appropriate for the current view
    are shown. Prior to this change all events were always shown.
    (Gitlab #429)

* 120 [func] marcin

    When Stork server pulls updated Kea configurations it detects those
    configurations that did not change since last update using a fast
    hashing algorithm. In case when there was no configuration change
    for a daemon, Stork skips processing subnets and/or hosts within
    this configuration. This improves efficiency of the configuration
    pull and update. In addition, when configuration change is detected,
    an event is displayed informing about such change in the web UI.
    (Gitlab #460)

* 119 [doc] tomek

    Prometheus and Grafana integration is now documented. Also, updated
    requirements section pointing out that stat_cmds hook is needed for
    Stork to show Kea statistics correctly.
    (Gitlab #433, #451)

* 118 [bug] marcin

    Prevent an issue whereby Stork server would attempt to fetch updated
    machine state while the request to add this machine is still being
    processed. This used to cause data conflict errors in the logs and
    network congestion.
    (Gitlab #446)

* 117 [build] marcin

    Upgraded Go from 1.13.5 to 1.15.5 and golangcilint from 1.21.0 to
    1.33.0.
    (Gitlab #457)

* 116 [perf] marcin

    Improved performance of connecting large Kea installation with many
    subnets to Stork. Adding subnets to the database is now much more
    efficient as it avoids extensive subnet lookups. Instead it uses
    indexing techniques.
    (Gitlab #421)

```

Thank you again to everyone who assisted us in making this release
possible.

We look forward to receiving your feedback.
