Clarizen vs ZenTao: at a glance
What is Clarizen?
Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.
The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.
What is ZenTao?
ZenTao posts a 22.0 beta with no notes in the feed.
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.

Clarizen

Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.
◆ Current state
The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.
◆ Where it's heading
Without substantive release content visible, product trajectory isn't observable from this feed. The continued AdaptiveWork branding reflects Planview's post-Clarizen-acquisition consolidation. Connect 2026 promotion suggests an upcoming customer event in late spring or summer.
◆ Prediction
Confident predictions aren't possible from this slice. A different ingestion target (per-version pages under success.planview.com/Planview_AdaptiveWork/00_AdaptiveWork_Release_Notes/...) would surface actual release content and let trajectory and prediction become real.
ZenTao
2.5PM
ZenTao posts a 22.0 beta with no notes in the feed.
◆ Current state
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.
◆ Where it's heading
A beta of a new major version suggests a larger release is in progress, but nothing in the feed says what it contains.
◆ Prediction
Unclear: the entry does not show what 22.0 changes or when a stable version will follow.
