What is Casdoor?
Casdoor ships a version bump per commit, and the recent run is all tenancy hardening.
Casdoor tags a release on nearly every merge — ten versions between August 4 and August 10, most carrying a single commit. The recent run clusters on two threads: multi-tenant isolation (cross-organization webhook restrictions, organization checks on add APIs, Casbin group rules following user renames) and DingTalk integration repair. Individually each release is small; read together they are a sustained pass over organization boundaries.
What is Tailscale?
Tailnets become API-provisioned resources while Tailscale hardens SSH and thins the control plane.
Tailscale is in a steady release cadence on the 1.102 line, with the substantive work landing in 1.102.1 and the two releases after it carrying only fixes and library bumps. That release added a Services-oriented CLI surface (tailscale get, whoami, service list), Serve byte metrics for Tailscale Services, and constant-time node addition and removal that cuts CPU on large tailnets. Separately, an alpha tailnet creation API turns tailnets themselves into programmable objects, and the admin console has moved to its own subdomain. A 1.98.10 backport closed two Tailscale SSH vulnerabilities on the older branch.

Casdoor
5.0INFRA · APIS
Casdoor ships a version bump per commit, and the recent run is all tenancy hardening.
◆ Current state
Casdoor tags a release on nearly every merge — ten versions between August 4 and August 10, most carrying a single commit. The recent run clusters on two threads: multi-tenant isolation (cross-organization webhook restrictions, organization checks on add APIs, Casbin group rules following user renames) and DingTalk integration repair. Individually each release is small; read together they are a sustained pass over organization boundaries.
◆ Where it's heading
The organization is becoming the unit of configuration. Record retention days, default token format, master-password hashing and LDAP visibility all became per-organization concerns inside a single week. That is the shape of a project hardening for multi-tenant deployment rather than adding end-user features, and the cross-organization webhook restriction in the newest release is the clearest statement of it so far.
◆ Prediction
Expect the per-organization configuration surface to keep growing and more cross-organization access checks on the remaining endpoints, since the last week has moved steadily in that direction. The per-commit release cadence means this will arrive as another ten small versions rather than one milestone.
Tailscale
6.3INFRA · APIS
Tailnets become API-provisioned resources while Tailscale hardens SSH and thins the control plane.
◆ Current state
Tailscale is in a steady release cadence on the 1.102 line, with the substantive work landing in 1.102.1 and the two releases after it carrying only fixes and library bumps. That release added a Services-oriented CLI surface (tailscale get, whoami, service list), Serve byte metrics for Tailscale Services, and constant-time node addition and removal that cuts CPU on large tailnets. Separately, an alpha tailnet creation API turns tailnets themselves into programmable objects, and the admin console has moved to its own subdomain. A 1.98.10 backport closed two Tailscale SSH vulnerabilities on the older branch.
◆ Where it's heading
Two threads are running in parallel. The first is scaling the tailnet as infrastructure: constant-time node churn, an API for creating and deleting tailnets, and a growing CLI vocabulary around Tailscale Services all point at tailnets being provisioned and torn down programmatically rather than administered by hand. The second is tightening the identity edge, with SSH permission checks patched on both the current and previous branches and Funnel certificate renewal moved to TLS-ALPN-01. The version-numbered releases increasingly carry plumbing while the named features carry the direction.
◆ Prediction
The tailnet creation API graduating from alpha, with the per-tailnet lifecycle exposed through the same CLI and policy surface as nodes, is the natural next step. Continued Services-related CLI and metrics additions on the 1.102 line look likely given how much of 1.102.1 went that way.
