Description

• With the last release we enabled ML preloading by default. ML preloading disables viewport-based preloading.
• The ML based preloading can fail, e.g. for malformed configs, invalid models...
• In those cases we want to fall back to vp-based preloading.

New features

• If ML preloading fails, fall back to VP preloading

• if that fails, try again

Changed features

• n/a

Removed features

• appName config option
• visualizationStyles config option - was not in use and feature is not longer planned ‏

Description

Tests are still flaky in four instances:

• failure cause preload limit
• failure cause preload limit
• preload on hover (unit)
• preload on hover (e2e)

Also, sometimes the entire pipeline can fail because we source the anybadge script from a remote git that has its own availability problems. We need to copy that to local.

New features

n/a

Changed features

• added safeguards to test to increase stability
• source anybadge locally

Added support for proper handling of target="_blank" links in PrerenderService with separate speculation rules.

Description

Enhanced the PrerenderService to separately track and handle links with target="_blank" attributes. The implementation now creates distinct speculation rules with appropriate target_hint for blank links, ensuring they open in new tabs as expected while still benefiting from prerendering.

New features

• Added support for target="_blank" links in PrerenderService
• Created separate speculation rules for blank target links with target_hint="_blank"
• Maintained separate URL tracking for regular and blank target links
• Added comprehensive test coverage for blank link handling

Changed features

• Modified speculation rule generation to include target_hint based on link type
• Updated URL tracking to prevent mixing regular and blank target URLs

Removed features

None ‏
