What is Casdoor?

Casdoor is spending its release cadence moving auth checks from the client to the server

Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.

What is simDAG?

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

Casdoor is spending its release cadence moving auth checks from the client to the server

◆ Current state

Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.

◆ Where it's heading

Read together, these commits describe one job: closing the gap between what the console enforces and what the backend enforces. Several of them move a check that previously lived in the UI into the server, which is the work of a project being deployed into environments that audit it. New authentication providers and integrations have thinned relative to this hardening pass.

◆ Prediction

The next releases most likely continue the same sweep - remaining endpoints where an admin or user request is trusted more than the server verifies - rather than adding a new identity provider.

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

◆ Current state

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

◆ Where it's heading

The package has been widening what a simulation can represent rather than deepening any one node. Networks arrived in 0.4.0 so individuals could depend on each other, discrete-event simulation in continuous time arrived in 0.5.0 as an alternative to the discrete-time engine, and 1.0.0 connected the two by letting continuous hazards feed the event-driven path. Alongside that, node types keep accumulating for outcome families the framework could not previously generate.

◆ Prediction

Expect the node library to keep expanding into outcome types the discrete-event engine can now support, though the recent releases suggest upstream dependency churn will keep consuming release slots.
