Version 4.1.0 (2022-04-19)

General

Brainz, agent, router and api-gw now adds timestamps to log outputs by default. This can be turned off via -log-timestamps flag.
Store 300 chars of log messages instead of 200 for warning/errors in system debug logs.
Improved error message when NATS fails to connect.

Brainz

Improved log outputs for agent and routers where each log message now starts with Agent <agent_name>:<agent_id> for agent related logging and Router <router_name>:<router_id> for router related logging.
More stable deployments for large VCL’s that takes longer time to compile.
Existing users with account permissions will get new router related permissions added automatically to their account.
Fixes a bug where statistic description updates could in certain conditions cause a deadlock in psql.
Added draft for the name of files and VCLs, so automatic deployments will not break Varnish.
Fix a bug where related VCLGroups were not deployed if they share an include.
Fix a bug where a VCLGroup could stay in a compiling state due to a deadlock.

Router

Tags for routers now support dashes.
Support for custom routing decisions via gRPC plugins (see Routing Plugins)
RoutingRules can now have plugins in lookup-order such as plugin:1.
Support for running both HTTPS and HTTP routing at the same time on different ports.
http-tls replaced by https-routing.
https-port and https-host added for HTTPS routing.

CLI

Support for proxy via -proxy flag.
New commands for gRPC and RoutingPlugins (plugingrpc, routingplugin).
Link to documentation updated to correct URL.
Improve revoke tokens when changing perms, instead of a question it is now a flag that can be set --revoke.

Agent

Support for wildcard in Varnish statistics counters (e.g. *client_*).

API-GW

REST API support for gRPC plugin and routing plugins.
Fix a bug where you could not use the ?file_type=1 filter on the files and vcls endpoints.
Fix a bug where there was no filter on organization level on some endpoints.
Deprecation warning! The operator=and filter sometimes does not give the desired result. To be more flexible we implemented [all] if you want to filter on entities that have for example all of the tags use ?tags.id[all]=1,2. The operator=and will be removed in the next major release (5.0.0).

Major redesign of the Editor.
Added new section for support, including debug feature for sysadmins.
Added login modal when token expires, less interruptive workflow.
Added support for routingplugins, and grpc.
Changed the layout of ’Staged VCLGroups’ in tables, modal and various stability fixes.
Changed dashboard-widget to make it possible to use multiple custom-equations in the same widget.
Changed ordering of tags in tables to be ordered by A-Z.
Fixed a bug that made the drag’ n drop function in routing rules behave inconsistent.
Fixed a bug where some form-fields broke on specific window widths.
Adjusted dashboard-widgets due to a backend issue where AND didn’t work as expected when selecting multiple counters.
Fixed a bug where duplicating a dashboards reset the values on the default dashboard.

Version 4.0.0 (2022-02-17)

General

Debug information now includes last 50 (Warning/Error) stdout messages.

Brainz

Automatic deployment retries to previously failed agents.
Statistics for the router.
RouterDebug included in system debug for routers.
New permission types:
- Router
- RoutingRules

An issue where configuration values wasn’t overridden properly for values: true/false when using multiple types of configurations such as configuration file and environment variable for the same value has been fixed.
Fixed a bug where duplicate tags could be created when agents would report them in at the same time.
Added the option to revoke logged in sessions for the UI when changing permissions.
Improved deployment and undeployment.
Fixed a bug where intermittent deployment failures after restart were happening.
Added a deployment retry backoff algorithm if a deployment previously failed on an agent, the Varnish Controller will check the last failure date and time and wait a little before trying to deploy again to avoid spamming the agent.
Fixed a bug where you could deploy the same domain on the same agent multiple times by changing the domain or deployment configuration of the VCLGroup.
Fixed a bug where the JWT token after login became too big to store in a cookie for the UI, therefore the user could not login into the UI.
Fixed a bug where the pagination did not work.

Agent

Breaking Removed varnish-port configuration option. The port is now defined in the varnish-host, by default 127.0.01:6081 is used. The following formats should be used example.com:8080.
