Improved handling of invalidation deployment history data
Version 6.4.1 (2024-09-20)
UI
Ability to configure HTTPS for IDP redirects on the varnish-controller-ui (-idp-https-redirect).
Brainz
Fixed a bug that prevented comma-separated ID filtering for specific resources (domains, configsets, tagroutes).
Version 6.4.0 (2024-09-17)
General
Updated NATS to latest version: 2.10.20.
Binaries built with Go 1.23.1.
Fixes a migration bug where file labels where reset during upgrade from a version prior to 5.3.0.
Agent
Shared deployments now have 2 new headers added to the request to see which VCLGroup name and Agent name the request came from.
X-Agent-Name
X-VCLGroup-Name
The agents now supports to gather statistics per domain. This has to be enabled manually and it will increase the size of the statistics depending on number of domains deployed.
Enabled via -domain-stats, this can be enabled through the CLI or UI with the configurations or configuration sets.
Changes to statistics sampling in the agents
A new flag (-stats-filter) has been introduced to the agents, used to configure statistics with one flag, supporting wildcards. Use either this or the old statistics filters
The new -stats-filter will now supersede the -vclgroup-stats-filter, -agent-stats-filter and -accounting-stats-filter (which will be deprecated in the next major release).
The new filter also supports filtering of accounting keys, with wildcard support.
The root VCL has been updated to support domain statistics.
Router
BaseURL for agents and external routes in the router is now stripped from the trailing / to avoid getting location set with double slashes (//).
VCLI
Fixes a bug where file state where not updated correctly, causing VCLGroup deployment with --wait time out when no changes to a file had been made.
UI
Fixes a bug in UI CDN map when changing default data.
Version 6.3.2 (2024-07-10)
General
Updated NATS to the latest version: 2.10.17.
Version 6.3.1 (2024-07-10)
Agent
Backups on agents will now only be taken if there are deployments. This will remove a previous warning message that wasn’t critical.
UI
Version of varnish-controller-ui showed 0.0.0 in the 6.3.0 release, this has been fixed.
The UI now validates the IDP client secret less strict.
Version 6.3.0 (2024-07-08)
General
Binaries built with Go 1.22.5.
This release includes the Basic Invalidation feature. This feature is exclusively API/CLI-based for integration purposes, designed for both heavy-duty and straightforward purging tasks.
Version 6.2.0 (2024-06-18)
Important
Previous versions of the Varnish Controller aggregated UDO dynamic backends and S3 VMOD statistics with the IP and port in the counter names.
These old statistic names will be deleted upon upgrading to version 6.2.0.
The Varnish Controller agent will normalize the counter names and remove the IP and port to get a better aggregation of your statistics.
This could take some time with larger databases.
General
Binaries built with Go 1.22.4.
Brainz
Fixed an invalidation bug that occurred when specifying multiple domains belonging to different VCLGroups but deployed with the same tag.
Fixed an issue where non-monitored invalidations could remain in a running state if a connection loss occurred with Brainz or the agent during the invalidation process.
Agent
Agents now creates a backup directory in its base-dir called backup. This directory contains last 20 deployment changes. See Agents.
Implemented normalization of S3 and UDO statistic counters.
Router
Reject Routes now support CNAME.
The default certificate that can be configured on the router via TLS management within the controller now uses a default cipher suite set for TLS v1.2 if none is specified.
CLI
vcli now supports to wait for deployments to be complete before returning. See VCLI Examples.
Version 6.1.3 (2024-05-29)
Brainz
Database performance improvements.
Agent
Use VCLGroup directory first when loading a VCL on agents, instead of system defaults.
Fixes a bug where vcl_path and vmod_path was generated with wrong defaults for cmds.cli file, when Varnish could not be reached.
UI
Fixed a bug in the editor where the file name in the tabs wouldn’t update as expected when renaming a file.
Version 6.1.2 (2024-05-20)
General
Binaries built with Go 1.22.3
Brainz
Fixed a bug in the invalidation handling when both VCLGroup and domain are provided as input arguments for shared deployments, but the domain didn’t exist, this will be rejected immediately.
Fixed a bug in the invalidation handling that could cause a request to remain in a running state even after the execution TTL had expired.
Changed log level to debug (from warning) for row not found when querying elements in the database which doesn’t exist.
File draft is now included in system debug.
Agent
Fixed a bug where the TLS version check failed for Varnish versions 6.0.13 and above.
Version 6.1.1 (2024-04-30)
Agent
Revert setting the TMPDIR environment variable for varnishtest to agent’s base-dir. In some cases the path set by the Agent would be too big for varnishtest, causing all VTC tests to fail.
UI
Show location of router traces in the UI.
Version 6.1.0 (2024-04-29)
General
Binaries built with Go 1.22.2
Decrease size of Varnish Controller gathers

JWT keys in brainz are now periodically generated and not just during start, letting brainz generate new keys more often.
Agent
Reload a VCLGroup on all agents or a specific agents.
Fix a bug where uptime was reported wrong if NTP was not synced before the agent started.
Fixes a bug where varnishtest was not ran with compile-timeout longer than the default of 60sec. This is now propagated correctly from brainz/api-gw compile-timeout configuration.
Fixes a bug where vcl_path and vmod_path could contain the agent’s base-dir multiple times.
Fix a bug for large VCL files that made the deployment time out.
Make sure exit code is always verified when validating with varnishtest on the agent.
Set TMPDIR environment variable for varnishtest to agent’s base-dir.

Fixed a bug where selecting a domain in a VCLGroup would only show 20 domains.
Version 6.0.1 (2024-02-28)
General
Output from -generate-config was missing its configuration section, now added correctly again. This affected brainz, agent, router and api-gw binaries.
The agent/router were not syncing updated environment/argument values correctly on restart. This meant
that when changing an environment variable for the router/agent, it was not reflected in the database until any configuration was changed
via the API. This is now fixed.
Brainz
Fix a migration issue that could affect Routing Rules cors_origin and cors_methods becoming lost during 6.0.0 upgrade.
Log entries for transferring an agent/router is now created for generated private tokens.

Improved API filtering.
Brainz
Fixes several database warnings (duplicate keys).
Only token owners can now see shared organizations for a given shared token.
Fixed an issue where statistics could be retrieved for a private agent by a user not owner of the agent.
