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 Fail2Ban?

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door

Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.

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.

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door

◆ Current state

Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.

◆ Where it's heading

The pattern is long silences broken by releases that mostly absorb external change — Python 3.12 and 3.13 compatibility in 1.1.0, a Dovecot filter regression in 1.0.2 — with the substance deferred to a ChangeLog the feed does not carry. What is different this time is the contributor list, which runs to a dozen first-time contributors, suggesting the delay was throughput rather than abandonment. The release also had to be re-cut: the first Debian package shipped with wrong paths from a missing systemd-dev build dependency and was pulled and replaced.

◆ Prediction

Given the beta-to-final gap just closed and the volume of first-time contributors merged into it, the useful thing to watch is whether the next release arrives in months rather than years; the entries do not indicate what it would contain.
