Stork 0.13.0, November 6th, 2020, Release Notes
Welcome to the Stork 0.13.0 release. This is a development release of the Stork dashboard.
The changes introduced in this version are:
Better handling for large Kea deployments. Earlier Stork releases were unable to effectively monitor large Kea deployments. One specific failure report mentioned issues with monitoring a Kea installation with 4500 subnets: processing a response to the
config-getcommand was very slow, effectively causing the system to hang. This particular problem has been addressed and Stork can now be connected to significantly larger Kea deployments. We are aware of other bottlenecks; in particular, there is one causing high CPU utilization during Kea status updates (see #421 (closed)). We are working on addressing these limitations.
Receiving statistics from Kea 1.8.0. Some of the DHCPv4 lease statistics were renamed in Kea 1.8.0 and earlier Stork versions did not recognize them. Stork can now recognize both the statistics returned by Kea 1.8.0 and the earlier Kea versions (#413 (closed)).
Handling IP address changes. Earlier Stork releases did not properly handle a situation when an address or port of the Kea Control Agent changed. As a workaround, it was possible to remove and add a specific machine again; this is no longer necessary (see #409 (closed)). Stork now detects Kea Control Agent's IP address/port change and uses the new address/port for further communication.
Major testing efforts. Stork has been in development for over a year and during that time, we have delivered many new features. To ensure that the project provides high-quality software that is maintainable over the long term, we needed to step back and invest some effort in testing capabilities. Previously we had only backend unit-tests. With this release, we added two new significant capabilities. First, we added WebUI unit tests; as of this release, we have 49 such tests. Those tests are now part of our automated CI system (#164 (closed)). Second, we made substantial improvements to the system tests, of which we now have seven. Although that number is still small, each system test covers a wide spectrum of features, such as installing or upgrading packages on CentOS and Ubuntu; testing whether it is possible to use the UI to add a new user with lower privileges and confirming that the new user is not allowed to create more users; testing Stork with a Kea configuration with many subnets; and more (#412 (closed)). The Developer's Guide has been extended (#427 (closed)). Finally, we've improved our internal building and deployment scripts. This change is invisible to users, but it improves our development process (#402 (closed), #400 (closed)).
UI improvements. The "see more" link on the dashboard now leads to a subnets view and the subnets are filtered appropriately (#389 (closed)). The HA status information presented on the dashboard and Kea app view was corrected for cases when the HA had not been configured or the HA state had not yet been fetched (#277 (closed)).
Debian 9 support. A problem with building on Debian 9 has been spotted and fixed (#423 (closed)).

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.
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.
The following summarizes changes and important upgrades since the Stork 0.12.0 release.
* 115 [func] marcin Improved presentation of the HA server scopes. Added a help tip describing expected HA scopes in various cases. (Gitlab #387) * 114 [bug] godfryd The links on the dashboard to subnets and shared networks have been adjusted so they take into account DHCP version. This way subnets and shared network pages automatically set filtering by protocol version based on parameters provided in URL. (Gitlab #389) * 113 [bug] godfryd Fixed handling renamed statistics from Kea. In Kea 1.8 some of the statistics have been renamed, e.g. total-addreses to total-addresses. Now Stork supports both of the cases. (Gitlab #413) * 112 [bug] godfryd Fixed handling situation when IP address of Kea Control Agent has changed. Till now Stork was not able to detect this and was still communicating to the old address. Now it checks if address has changed and updates it in the database. (Gitlab #409) * 111 [bug] marcin Corrected presentation of the HA state in the dashboard and the HA status panel in cases when HA is enabled for a server but the HA state information was not fetched yet. In such cases a spinner icon and the 'fetching...' text is now presented. (Gitlab #277) * 110 [bug] marcin The rake build_agent task now supports building the agent using wget versions older than 1.19. Prior to this change, the agent build was failing on Debian 9. (Gitlab #423) * 109 [doc] tomek Updated Prerequisites section. We now have a single list of supported systems. (Gitlab #431) * 108 [test] tomek, marcin Corrected and extended existing boilerplate WebUI unit tests. (Gitlab #164) * 107 [bug] godfryd Fixed problem of adding Kea with 4500 subnets. Now messages with Kea configuration sent from Stork Agent to Stork Server are compressed so it is possible to sent huge configurations. Added new Kea instance to Stork demo with 7000 subnets. (Gitlab #398) * 106 [doc] godfryd Added documentation for Stork system tests. The documentation describes how to setup environment for running test tests, how to run them and how to develop them. (Gitlab #427)
Thank you again to everyone who assisted us in making this release possible.
We look forward to receiving your feedback.
