This release introduces fully offline licensing for air-gapped and restricted-network deployments, augmenting the proprietary Chromium extension used for web automation with an industry-standard Selenium engine, and delivers a broad set of optimization and performance improvements across the platform. {% hint style="info" %} **Important: Migration deadline** Online (connected) licensing will reach **end of support on September 1st, 2026**. Before that date, all partners and customers must migrate to v26.3 and move to the new licensing model to avoid any interruption in service. The installation package can be located at **We recommend that Web automations built with the legacy Chromium extension tobe migrated to the new Selenium-based actions as part of the same upgrade**, since general Chromium-based browser policies are increasingly more and more restrictive, eventually leading to a very limited set of actions that will be supported in the future. {% endhint %} ## New features #### Offline Licensing for Air-Gapped Environments TAP now supports fully offline license activation and validation, removing the previous requirement for an outbound connection to the Tailent licensing service. This enables deployment within air-gapped enterprise networks, public sector and critical infrastructure environments, and any setting where external connectivity is restricted or prohibited. Licenses can now be issued, activated and renewed through portable license files, with local cryptographic validation and no dependency on external endpoints. Online licensing remains available until its end of support on September 1st, 2026 (see migration notice above). Generated licenses can also be bound to particular unique machine identifier, ensuring the TAP Framework can only run on specific designated machines #### Selenium integration **TAP Studio**'s web automation capabilities have been re-platformed onto Selenium, augmentingthe in-house Chromium extension previously used to drive browser automations. The move was driven largely by changes outside Tailent's control. Google's transition of Chrome to Manifest V3 rendered the classic TAP Chrome extension unsupported and imposed less flexible automation capabilities under the banner of enhanced security — for example, injected JavaScript execution is no longer permitted by the browser. Rather than remain tied to a single vendor's extension model and its shifting restrictions, TAP web automation now also features Selenium, a widely adopted, open-standard engine. This delivers broader browser and version compatibility, more reliable element identification, and a more stable, maintainable foundation for future web automation features that is not dependent on browser-specific extension policies. Existing web actions map onto a new set of Selenium-backed actions, including instance management, XPath-based element location, and element interaction (click, set text, read value). You can find more details here: #### General improvements and optimizations * General runtime optimizations that reduce memory footprint and improve execution throughput for long-running and high-volume automations. * Faster solution load and save times, particularly for large solutions with many workflows. * Reduced startup time for TAP Studio and the TAP Assistant. * Improved stability of the communication channel between the automation engine and browser instances under the new Selenium engine. * Additional logging and diagnostics around licensing and web automation to simplify troubleshooting in restricted environments. #### Resolved issues This release of TAP Studio comes with many fixes and corrections: * **Issue #503** - fixed issue where license validation would intermittently fail on machines without persistent internet connectivity. * **Issue #508** - fixed issue where certain web element identifiers created with the legacy Chromium extension would not resolve correctly. * **Issue #512** - fixed issue where large DOM pages could cause increased memory usage during web automation runs. * **Issue #517** - fixed issue where TAP Studio would occasionally hang when closing a browser automation instance. * **Issue #521** - fixed issue where solution load times degraded on solutions containing a large number of web actions.
