= Network Observability Operator 1.10 fixed issues
7+
8+
[role="_abstract"]
9+
The Network Observability Operator 1.10 release contains several fixed issues that improve performance and the user experience.
10+
11+
[id="metricname-and-remap-fields-are-validated-flowmetrics_{context}"]
12+
== MetricName and Remap fields are validated
13+
14+
Before this update, users could create a `FlowMetric` custom resource (CR) with an invalid metric name. Although the `FlowMetric` CR was successfully created, the underlying metric would fail silently without providing any error feedback to the user.
15+
16+
With this release, the `FlowMetric`, `metricName`, and `remap` fields are now validated before creation, so users are immediately notified if they enter an invalid name.
17+

19+
20+
[id="export-overview-topology-freeze_{context}"]
21+
== Improved html-to-image export performance
22+
23+
Before this update, performance issues in the underlying library caused the `html-to-image` export function to take a long time, leading to browser freezing.
24+
25+
With this release, the performance of the `html-to-image` library has been improved, reducing export wait times and eliminating browser freezing during image generation.
26+
27+

28+
29+
[id="improved-warning-messages-on-missing-privileged-mode-for-ebpf-features_{context}"]
30+
== Improved warnings for eBPF privileged mode
31+
32+
Before this update, when users selected `eBPF` features that require `privileged` mode, the features would often fail without clearly informing the user that `privileged` mode was missing or needed to be enabled.
33+
34+
With this release, a validation hook immediately warns the user if the configuration is inconsistent. This improves user understanding and prevents misconfiguration.
35+
36+
link:https://issues.redhat.com/browse/NETOBSERV-2268[NETOBSERV-2268]
37+
38+
[id="source-destination-subnet-labels-in-open-telemetry-exporter_{context}"]
39+
== Subnet labels added to OpenTelemetry exporter
40+
41+
Before this update, the `OpenTelemetry` metrics exporter was missing the network flow labels `SrcSubnetLabel` and `DstSubnetLabel`, causing them to show as empty.
42+
43+
With this release, these labels are now correctly provided by the exporter. They have also been renamed to `source.subnet.label` and `destination.subnet.label` for improved clarity and consistency with `OpenTelemetry` standards.
44+
45+
link:https://issues.redhat.com/browse/NETOBSERV-2405[NETOBSERV-2405]
46+
47+
[id="reduced-default-tolerations-for-network-observability-components_{context}"]
48+
== Reduced default tolerations for network observability components
49+
Before this update, a default toleration was set on all network observability components to allow them to be scheduled on any node, including those tainted with `NoSchedule`. This could potentially block cluster upgrades.
50+
51+
With this release, the default toleration is now only maintained for the `eBPF` agents and the `Flowlogs-Pipeline` when configured in `Direct` mode. The toleration has been removed from the {product-title} web console plugin and the `Flowlogs-Pipeline` when configured in `Kafka` mode.
52+
53+
Additionally, while tolerations were always configurable in the `FlowCollector` custom resource (CR), it was previously impossible to replace the tolerations with an empty list. It is now possible to replace the tolerations with an empty list.

[role="_abstract"]
9+
Review the following known issues and their recommended workarounds (where available) that might affect your use of the Network Observability Operator 1.10 release.
10+
11+
[id="eBPF-agent-compatibility-with-older-open-shift-versions_{context}"]
12+
== eBPF agent compatibility with older {product-title} versions
13+
The eBPF agent used in the Network Observability Command Line Interface (CLI) packet capture feature is incompatible with {product-title} versions 4.16 and older.
14+
15+
This limitation prevents the eBPF-based Packet Capture Agent (PCA) from functioning correctly on those older clusters.
16+
17+
To work around this problem, you must manually configure PCA to use an older, compatible eBPF agent container image. For more information, see the Red Hat Knowledgebase Solution link:https://access.redhat.com/solutions/7132671[eBPF agent compatibility with older Openshift versions in Network Observability CLI 1.10+].

= Network Observability Operator 1.10 new features and enhancements
7+
8+
[role="_abstract"]
9+
The Network Observability Operator 1.10 release enhances security, improves performance, and introduces new CLI UI tools for better network flow management.
10+
11+
[id="network-policy-updates_{context}"]
12+
== Network policy updates
13+
The Network Observability Operator now supports configuring both ingress and egress network policies to control pod traffic. This enhancement improves security.
14+
15+
By default, the `spec.NetworkPolicy.enable` specification is now set to `true`. This means that if you use Loki or Kafka, it is recommended that you deploy the Loki Operator and Kafka instances into dedicated namespaces. This ensures that the network policies can be configured correctly to allow communication between all components.
16+
//check if deploying Loki and Kafka in dedicated namespaces is included in the updated network policy, "Configuring network policy". Might need to add an IMPORTANT admonition to that section.
17+
18+
[id="network-observability-operator-cli-ui-updates_{context}"]
19+
== Network Observability Operator CLI UI updates
20+
This release brings the following new features and updates to the Network Observability Operator CLI (`oc netobserv`) user interface (UI):
21+
22+
*Table view enhancements*
23+
24+
* Customizable columns: Click *Manage Columns* to select which columns to display, and tailor the table to your needs.
25+
* Smart filtering: Live filters now include auto-suggestions, making it easier to select the right keys and values.
26+
* Packet preview: When capturing packets, click a row to inspect the `pcap` content directly.
27+
28+
*Terminal-based line charts enhancements*
29+
30+
* Metrics visualization: Real-time graphs are rendered directly in the CLI.
31+
* Panel selection: Choose from predefined views or customize views by using the *Manage Panels* pop-up menu to selectively view charts of specific metrics.
32+
33+
[id="network-observability-console-improvements_{context}"]
34+
== Network observability console improvements
35+
The network observability console plugin includes a new view to configure the `FlowCollector` custom resource (CR). From this view, you can complete the following tasks:
36+
37+
* Configure the `FlowCollector` CR.
38+
* Calculate your resource footprint.
39+
* Gain increased of issues such as configuration warnings or high metrics cardinality.
40+
41+
[id="network-observability-operator-performance-improvements_{context}"]
42+
== Performance improvements
43+
Network Observability Operator 1.10 has improved the performance and memory footprint of the Operator, especially visible on large clusters.
