What is Kanboard?

Six straight releases of security hardening, now reaching the API's own response shape

Kanboard is a stable, self-hosted PHP kanban board whose release stream is now almost entirely security work. Version 1.2.54 continues that pattern and pushes it further than most: API procedures no longer return private user fields, and changing a password invalidates every existing session and remember-me token. Feature development is close to dormant; the maintenance effort is going into closing whole categories of vulnerability rather than adding surface.

What is Productboard?

Productboard v2 makes entity types per-workspace, breaking fixed-enum clients in favor of extensibility

Productboard's v2 API has been on a steady expansion path through summer: fulltext search for notes, company source metadata, team and tag filtering, custom field presence filters. These entries fill v1 parity gaps. The September 22 EntityType change is the first real breaking move — shifting from a fixed enum to an open string that varies by workspace. Clients that assumed a fixed set of entity types now need to query the workspace's entity configuration to get the authoritative list.

Kanboard vs Productboard: editorial side-by-side

K2.5

Six straight releases of security hardening, now reaching the API's own response shape

◆ Current state

Kanboard is a stable, self-hosted PHP kanban board whose release stream is now almost entirely security work. Version 1.2.54 continues that pattern and pushes it further than most: API procedures no longer return private user fields, and changing a password invalidates every existing session and remember-me token. Feature development is close to dormant; the maintenance effort is going into closing whole categories of vulnerability rather than adding surface.

◆ Where it's heading

The arc from 1.2.49 through 1.2.54 is a systematic audit that works outward from one surface to the next — LDAP escaping, SSRF, deserialization, CSRF, comment visibility, bulk-operation ownership, and now API response shape and session lifetime. Each release also tightens the deployment story, from trusted-proxy configuration to an nginx config that only lets front controllers execute PHP. New user-facing features arrive rarely and small: opt-in full-text search, RTL support, richer API links.

◆ Prediction

Expect the audit to keep moving through remaining surfaces, with more permission checks in API procedures and continued PHP-version and base-image maintenance. Nothing in these entries points to a new feature direction.

P6.3

Productboard v2 makes entity types per-workspace, breaking fixed-enum clients in favor of extensibility

◆ Current state

Productboard's v2 API has been on a steady expansion path through summer: fulltext search for notes, company source metadata, team and tag filtering, custom field presence filters. These entries fill v1 parity gaps. The September 22 EntityType change is the first real breaking move — shifting from a fixed enum to an open string that varies by workspace. Clients that assumed a fixed set of entity types now need to query the workspace's entity configuration to get the authoritative list.

◆ Where it's heading

The EntityType shift is the foundation for workspace-specific schema customization in v2. The pattern across the June–September entries is: close v1 parity gaps, then add extensibility hooks. The beta customer score endpoint signals that Productboard is adding analytics surfaces on top of the data model, not just read/write operations.

◆ Prediction

The beta customer score endpoint will likely reach GA in a subsequent release as usage accumulates from enabled workspaces. Dynamic entity types will likely unlock workspace-specific filtering and field configuration in later API releases.
