The structured lifecycle lets you explore and provide feedback on new capabilities as they mature. Every Aviatrix feature moves through GA, Preview, and Early Access (EA) stages before general release. Each stage gives you a defined level of support and stability, and an opportunity to try new capabilities and provide feedback before they mature. Every Aviatrix feature falls into one of three modes in the following table: | Feature Mode | Aviatrix Support | Stability | Enable Method | | ------------ | ----------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- | | **GA** | Full support:
• Standard Aviatrix support channels
• SLAs | • Stable APIs
• Stable behavior
• Stable configuration

Breaking changes follow standard deprecation policy | Automatic | | **Preview** | Standard Aviatrix support channels | Some APIs and capabilities may change between Preview and GA | • From the CoPilot UI
• From the feature flag toggle on the **Settings** page | | **EA** | Best-effort support:

Aviatrix creates a support plan for the feature after approval | Significant changes may occur on:
• APIs
• Capabilities
• Configuration

The EA build may require manual reconfiguration when it upgrades to Preview or GA | Contact your Aviatrix account team | ## General Availability (GA) Features GA features have passed Aviatrix's standard release validation and are fully supported and safe for deployment in production environments. All Aviatrix features are GA unless otherwise mentioned. ## Preview Features Preview features are functional, supported, and available to all Aviatrix users. They are in the final stages of development, with a high likelihood of becoming GA. Preview features are an opportunity for you to evaluate upcoming capabilities and share feedback that shapes the final product. ## Early Access (EA) Features EA features are in active development and available to a select group of Aviatrix users upon request. They let you influence the direction of a feature in its earliest stages. EA features are not guaranteed to advance to Preview or GA. ## Adopt Preview and EA Features Safely Not all preview features carry the same scope of impact on your environment. Some are read-only visibility features that you can enable anywhere. Others modify traffic behavior and are best tried on a single Gateway first. The [Feature Classification](#feature-classification) table classifies every Preview and EA feature so you can choose a safe starting scope for each one. ### Impact Scope Levels Read and understand the following legends before going to the [Feature Classification](#feature-classification) table. | Icon | Level | Meaning | | ---- | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | 🟢 | **Explore Freely** | This feature provides visibility, analytics, or recommendations. It does not modify your network configuration or traffic. Enable it in any environment. If the data looks off, use your best judgment and report it through the feedback channel described below. | | 🟡 | **Start Small** | This feature can modify traffic behavior or configuration, but you control exactly where it applies. Enable it on a single non-critical Gateway or VPC, observe, then expand when you are comfortable. See the following feature notes for guidance. | | 🟠 | **Test First** | This feature operates across a broader scope: a Transit domain, multiple Gateways, or a cloud-wide setting. Try it in a dedicated test environment or non-critical Transit domain before broader deployment. | | 🔴 | **Lab Recommended** | This feature involves fundamental infrastructure changes that affect your network globally and cannot be scoped to individual Gateways. Evaluate it in an isolated lab or test environment during the preview period, and report what you find. | ### Feature Classification Transit Gateways carry traffic for multiple VPCs and Transit domains. Any inline feature enabled on a Transit Gateway carries a broader impact scope than the same feature on a Spoke. The feature classifications assume that you follow the guidance to start on Spoke Gateways. If you enable a feature on a Transit Gateway, consider it as one level broader in scope. Several DCF features can be configured with policies in logging-only mode (no enforcement action). While logging mode is lower risk than enforcement, DCF still inserts into the data path when enabled. Logging mode is a good first step for observation, but it is not the same as no impact. The feature classifications account for this. The following table classifies every Preview and EA feature so you can adopt each one with confidence. For DCF features, **Stage** and **GA Version** mirror the per-version history maintained in the DCF Supported Capabilities table, which is the source of truth if the two ever disagree. This table adds Impact Scope and Minimum Safe Scope guidance that the capabilities table does not cover. | Feature | Stage | Impact Scope | Version Introduced | GA Version | Minimum Safe Scope | | ------------------------------ | -------------- | ------------------ | ------------------ | ---------- | --------------------------- | | DCF IPS/IDS | GA | 🟡 Start Small | 8.2 | 9.0 | Single Spoke Gateway | | DCF TLS Profiles | Preview | 🟡 Start Small | 8.2 | — | Single Spoke Gateway | | DCF on Site2Cloud | Preview | 🟡 Start Small | — | — | Single S2C connection | | DCF on PSF | Preview | 🟡 Start Small | — | — | Single PSF Gateway | | DCF SNI Verification | Preview | 🟡 Start Small | — | — | Single Spoke Gateway | | Intra-VPC Distributed Firewall | Preview | 🟡 Start Small | — | — | Single VPC | | Edge Policy Based Routing | Preview | 🟡 Start Small | — | — | Single Edge Gateway | | ActiveMesh V4 | Preview | 🔴 Lab Recommended | 9.0 | — | Global (no scoping) | | Serverless Security | Early Access | 🟡 Start Small | 8.2 | — | Single VPC | | Hostname SmartGroups | GA | 🟡 Start Small | 7.2 | 8.1 | Per SmartGroup / Per policy | | Kubernetes SmartGroups | Preview | 🟢 Explore Freely | — | — | Per SmartGroup | | Kubernetes Node SmartGroups | Preview | 🟢 Explore Freely | — | — | Per SmartGroup | | External Groups | Preview | 🟢 Explore Freely | — | — | Per SmartGroup | | Egress VPC Score | Preview | 🟢 Explore Freely | — | — | N/A | | Topology Builder | Preview | 🟢 Explore Freely | — | — | N/A | | Geoblocking | Locked Preview | — | — | — | Not yet available | **Version Introduced** is the first Controller version where the feature became available in its current stage. **GA Version** is the target or actual version where the feature graduates to GA. A dash indicates the value is not yet determined. ### Feedback Preview features are available for you to try, and your feedback directly shapes what becomes GA. If you have questions, encounter unexpected behavior, or want to share suggestions: * Preview features: supported through standard Aviatrix support channels. * Early Access features: contact your Aviatrix account team for dedicated support. * In CoPilot: use the feedback button on any preview feature page.
