What is Backlog?

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

What is OpenProject?

OpenProject settles into patch work after 17.7 shipped resource management.

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

Backlog vs OpenProject: editorial side-by-side

Backlog logo0.0

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

◆ Current state

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

◆ Where it's heading

The real work is concentrated on planning views — Gantt scale, chart grouping, issue filtering — and on closing gaps between the web app and the mobile clients. Several changes are explicitly gated to Premium and Platinum plans, so view sophistication is being used as tier differentiation. Nothing here suggests a change of direction; it is a mature tracker refining how work is visualised.

◆ Prediction

Given the run of chart and Gantt scale work, the next planning-view change is likely another axis of aggregation or filtering rather than a new surface. The scraped entries make cadence unreliable, so any stronger call would not be grounded.

O6.3

OpenProject settles into patch work after 17.7 shipped resource management.

◆ Current state

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

◆ Where it's heading

The release rhythm is a feature minor followed by a short tail of patches repairing the surface it just added, and this tail sits squarely in resource-management territory. Rate and non-working-day bugs are the predictable cost of shipping scheduling and cost tracking together. For self-hosted operators the advice does not change between these releases: take the patch.

◆ Prediction

Expect one or two more 17.7.x patches against the resource management surface before 17.8 opens a new feature line.
