April 2026 release notes

May 1, 2026 2 min read

A round-up of what shipped in April. Highlights: a redesigned timeline view, formula custom fields, and Slack message-action support.

New: Formula custom fields

Custom fields can now compute their value from other fields on the same task. Spreadsheet-style syntax — simple math, conditionals, date arithmetic, and string operations.

# Effort score from priority and estimate
PRIORITY_WEIGHT * ESTIMATE

# Days overdue
IF(STATUS != "done", TODAY() - DUE_DATE, 0)

# Composite display
CONCAT(ASSIGNEE, " — ", STATUS, " (", PRIORITY, ")")

Formulas re-evaluate when source fields change. Documented in task fields.

Improved: Timeline view

Major redesign. Faster rendering for projects with 500+ tasks (10x improvement on the worst cases), better dependency arrow routing, snap-to-grid for cleaner alignment. Critical path now highlights with a subtle red gradient instead of solid color.

New: Slack message actions

Right-click any Slack message and choose Lattica → Create task. The message becomes a new task with the original Slack thread linked back. Replies in the Slack thread continue to sync.

New: Bulk export of attachments

Workspace exports now bundle attachments as actual files in the export zip, not just URLs. Good for archival and migration scenarios.

Improved: Search ranking

The search modal now weights recency and your interaction history. Tasks you’ve opened recently surface first. Recent comments are searched alongside titles and descriptions.

Fixed

  • Recurring tasks across daylight-saving boundaries no longer skip a day in the Pacific timezone.
  • Bulk-edit on board view respected the wrong column when filters were active.
  • Mobile app crashed on iPad when rotating during quick-capture (rare).
  • Webhooks for task.due_soon were firing 23 hours early instead of 24 — now exactly 24h.
  • Custom field labels with emoji rendered as ? in PDF exports.
  • Markdown tables in task descriptions overflowed the side panel; they now scroll horizontally.

Deprecations

The legacy /v0 API is retired May 31, 2026 — it has been deprecated since November 2024. If you’re still on it, upgrade to /v1 using the migration guide in the API documentation. /v0 requests will start returning 410 Gone after the cutoff.

Coming next

In testing for May: workspace-level themes, AI summary on long tasks, and a cleaner mobile board view. If you want early access, opt in from Account → Beta features.
