TL;DR: New Gantt is now the default experience for all users. Along with this milestone, we've shipped the enhanced Critical Path, which includes Total Float & Free Float visibility, as well as PDF Export with a more streamlined sharing experience. Classic Gantt remains accessible during the transition.
Hi Community! 👋
We are excited to share that New Gantt is now the default Gantt experience for all! 🎉
Our team has been hard at work bringing fresh updates to Gantt over the past several months - not just reaching parity with Classic Gantt, but building an even better experience for your project planning.
If you've been following along, you've seen this journey unfold step by step through our previous updates:
Today, we're bringing it all together. Let's take a closer look at what's new! 🙌
New Gantt as the Default Experience
New Gantt is now what all users will see when they open a Gantt chart. It's built on a stronger, more modern foundation - delivering improved performance, better scalability, modernized visuals, and a smoother planning experience overall.
Here's a quick look at what's already included:
- Support for New Table View
- New filters and groupings
- Improved performance and scalability
- Modernized visuals and updated timeline rendering
- Public Links & Public Snapshots
- Fiscal Year support
- Manual ordering and other sorting methods
- New task bar sizing and milestone visuals
- Details Tooltips
- Default Density Mode support
- PDF Export
- Critical Path with Float visibility
Can you still switch back? Yes. Classic Gantt remains accessible while we complete the final planned improvements
Key Differences - Classic vs New Gantt Experience
If you're transitioning from Classic Gantt, here are a few changes in how things work:
Feature | Classic Gantt | New Gantt |
|---|
Column settings | Gear ⚙ icon | Use the Fields button in the toolbar |
Left panel resize | Full collapse only | Drag to resize the table panel to any width, or collapse it fully |
Sharing & export | PDF via three-dot menu; snapshots via globe icon | The Globe icon is now the home for everything - public link, public snapshots, and PDF export all in one place |
Subitems expand/collapse | Subitems panel | Use the Subitems button in the toolbar - options include projects & tasks structure, single list, collapse all, and expand all |
Roll-ups | Manual - right-click and choose Item or Branch roll-up each time | Automatic - set once per level (item, sub-item, or parent). No manual trigger needed |
Roll-Ups: From Manual to Automatic
One of the biggest changes in New Gantt is how date propagation works.
Classic Gantt used manual roll-ups - you had to right-click an item each time and choose between Item roll-up (project dates update based on direct children only) or Branch roll-up (subtask dates update first, then tasks, then project).
New Gantt uses automatic roll-ups - set once per level and you're done. Options include:
- Item level - uses its own dates
- Sub-item level - subtasks drive parent task dates
- Parent level - full chain upward
No manual trigger needed on each change. If you previously relied on manual roll-ups, the new version is much simpler - just configure the level once and let Gantt handle the rest.
For more details on how automatic rollups work you can check out the Help Center article.
Critical Path in New Gantt
Critical Path is now available in the New Gantt chart, giving you the same core functionality you relied on in Classic Gantt - now in a faster, more modern experience.
Coming soon, Critical Path will also handle weekends for default work schedules and milestones with greater accuracy, delivering more confidence in real planning scenarios.
Enhanced Critical Path with Float Visibility
This is a brand-new capability, unique to the New Gantt experience!
Critical Path helps you understand what drives your project's finish date and where schedule risk exists.
Previously, you could see which tasks were marked as critical, but the red chain could sometimes be hard to interpret. More importantly, there was no way to understand how much scheduling flexibility existed or why a specific task was considered critical. That's where Float visibility comes in.
That changes with this update. Here's what's possible:
- Total Float and Free Float are now visible directly in New Gantt
- Float values appear both as table columns and directly on the Gantt canvas
- Critical Path calculations are now more reliable in common planning scenarios involving dependencies, weekends, and project end dates
- Negative Float visibility helps teams identify when projects or successor tasks are already behind schedule
- Teams can now better understand why tasks are critical and where scheduling buffer exists
Why Does Float Matter?
Float is a standard project management concept used to understand scheduling flexibility and project risk:
- Total Float - shows how much a task can move before impacting the overall project finish date
- Free Float - shows how much a task can move before impacting successor tasks
This helps teams better understand which work is truly critical, where buffer time exists in the schedule, and when delays are starting to create risk.
These improvements are especially valuable for PMOs, manufacturing teams, and enterprise project teams managing complex, dependency-heavy schedules where understanding scheduling risk and project timing is critical.
ℹ️ Please note that these enhancements are available only in the New Gantt chart.

PDF Export in New Gantt
You can now export your Gantt charts to PDF directly from the new experience.
Previously, PDF Export was located under the three-dot menu. It's now available under the Globe/Public Sharing icon in the toolbar - alongside Public Links and Public Snapshots - keeping all sharing and export options in one convenient place.
This brings PDF Export to parity with Classic Gantt. Work on further PDF improvements, including layout and quality enhancements, is already in progress and will follow in upcoming updates.

What's Coming Next
We're not stopping here! Here's what's on the roadmap:
- Critical Path support for custom work schedules and days off
- Critical Path filtering capabilities
- Start Constraints support
- Further PDF layout and quality improvements
- Additional parity and workflow improvements
Classic Gantt will remain available while these remaining features are added.
