Long-Term Service Branch (LTSB)

To ensure stable and manageable updates, 1E has introduced the Long-Term Service Branch (LTSB) policy for the 1E Client. Understanding the operational challenges posed by frequent updates, we have implemented an annual LTSB release with 18-month support. This approach is designed to help businesses maintain a secure and efficient environment with less frequent, but more substantial updates.

Structure and Support

Each LTSB version will receive 18 months of support. The next LTSB release will follow in May of each subsequent year.

To ensure maximum security and stability, hotfixes will be provided for the latest LTSB release. These hotfixes, thoroughly reviewed by us, will address critical stability and security issues (P1 and P2). While the LTSB will not receive additional feature updates after its initial release, new features will be included in the next LTSB release the following year. However, regular hotfixes will be issued monthly.

Aligning LTSB support with the Platform on-premises and subsequent SaaS releases creates a structured and predictable support model. This approach offers not just a product, but a lasting partnership, promising reliability, proactive maintenance, and smooth upgrade pathways. By adopting this LTSB framework, we can continue to deliver top-tier Digital Employee Experience (DEX) solutions while ensuring a consistent and supported ecosystem for all customers.

  • Software.GetAllInstallations SCALE method: The new Software.GetAllInstallations SCALE method provides visibility into all software installed on a device, including both machine-level and user-level installations. It also includes support for Windows Store apps.

  • macOS device responsiveness metrics: The 1E Client now includes initial support for responsiveness metrics on macOS devices. This data is available through SCALE by querying the $OperatingSystemPerformance table family. It will be exposed in the Experience Analytics application in a future release of the Platform.

  • $DeviceInformation_Live table: A new $DeviceInformation_Live table is now available. It provides historical device inventory data, including:

    • Operating system version

    • Battery health

    • Memory

    • Device model

    • Manufacturer

Microsoft Visual C++ runtime dependency:

The 1E Client now uses Microsoft Visual C/C++ Runtime Library (MSVCRT) version 14.42.34438.0.

If an older version is installed on a device, other services that depend on the runtime library may restart during 1E Client installation.

  • Inventory Insights: 1E Client 24.5 includes enhancements that provide additional details for Inventory Insights when used with Platform 24.5 or later.

  • Default port update: The 1E Client now uses port 443 by default, aligning with a SaaS-first strategy. This change improves security and network compatibility.

    • Applies to Windows, macOS, and Linux devices.

    • Updates to the Client Deployment Assistant (CDA) reflect this change.

    Before broad deployment, perform a silent test installation on a representative device.

  • Anonymous client certificates: Starting with 1E Client 24.1, you can use client certificates that do not include a fully qualified domain name (FQDN) in the subject name.

    The 1E Client selects any valid, locally trusted client certificate. During connection to the Platform, the certificate is validated to ensure the trust chain is verified by the Platform.
