What is KeeWeb?

KeePass-compatible password manager frozen mid-patch-run since 2021.

KeeWeb is a browser and desktop client for KeePass KDBX files, and this release history captures one week in May 2021 plus a final release that July. The work is almost entirely reactive: browser extension connection failures, KDBX3 files with large attachments or compression disabled, macOS tray and quit behavior, old Chromium compatibility. The last release added Microsoft Teams storage and a OneDrive tenant override, and every release note ends with a donation appeal.

What is Nebula?

Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.

Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.

KeePass-compatible password manager frozen mid-patch-run since 2021.

◆ Current state

KeeWeb is a browser and desktop client for KeePass KDBX files, and this release history captures one week in May 2021 plus a final release that July. The work is almost entirely reactive: browser extension connection failures, KDBX3 files with large attachments or compression disabled, macOS tray and quit behavior, old Chromium compatibility. The last release added Microsoft Teams storage and a OneDrive tenant override, and every release note ends with a donation appeal.

◆ Where it's heading

The pattern in this window is a v1.18.x line under stress — six patch releases in ten weeks, most fixing the browser-extension integration and cloud storage backends rather than the core credential handling. Cloud storage was the direction it was still moving in: OneDrive tenant control and Teams storage were the last additions. Nothing has shipped since July 2021.

◆ Prediction

These entries give no indication of resumed development; anyone relying on KeeWeb should assume the browser extension and cloud storage integrations are unmaintained against the services they connect to.

Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.

◆ Current state

Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.

◆ Where it's heading

The project has moved from single-IPv4-per-node assumptions toward a genuinely flexible addressing model, and the security fixes since v1.10.0 map directly onto that change — the new certificate features widened what the code has to validate. v1.11.0 shifts attention to the operational surface instead: structured logging, corrected firewall reject-versus-drop semantics, and Windows WFP filters installed by default.

◆ Prediction

The stated plan to assert low-s signature form when validating certificates is the concrete next step visible in these entries; expect it to land as a breaking validation change in a future release.
