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.

What is Vikunja?

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

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.

V0.0

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

◆ Current state

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

◆ Where it's heading

The arc moves from feature-completion (S3 storage, drag-and-drop project moves, hover previews in late 2025) toward platform credibility — closing security gaps a self-hosted task tool needs to clear before serious team adoption. The rapid version-number jump from v1.0.0-rc4 to v2.2.1 in two months suggests v1.0 shipped and the team tagged a v2 line aimed at addressing accumulated authz debt. Expect the next several releases to keep the security-first posture rather than return to a feature push.

◆ Prediction

The next release will likely continue closing remaining authz edges (more IDOR audits, additional credential-stripping in API responses) and bundle a translations and dependency sweep. A user-facing feature push probably waits until the security work plateaus.
