What is Zellij?

Zellij is patching the shell-aware rewrite it shipped eight days ago.

Zellij 0.45.0 pushed the multiplexer past byte-shuttling: nested sessions became a supported workflow, the Kitty graphics protocol landed, and OSC 133 parsing gave it prompt-aware scrollback. 0.45.1 arrived eight days later to fix what that surface broke — SSH nested-session detection, OSC9 notifications misfiring against the OSC99 spec, and Kitty image clearing on stacked panes. The project is single-maintainer and funds itself through sponsorship.

What is Z-Wave JS?

Z-Wave JS v15.32.0 ships the findings of two full-codebase security reviews.

v15.32.0 is the result of two security and correctness reviews of the whole codebase. No major issues were found, but it hardens S2, ESPHome, Transport Service and config parsing, caps firmware file sizes, limits outstanding S0 nonces and makes every firmware update stage abortable. ESPHome encryption keys no longer need manual URL encoding, and the release adds seven device config changes.

Zellij is patching the shell-aware rewrite it shipped eight days ago.

◆ Current state

Zellij 0.45.0 pushed the multiplexer past byte-shuttling: nested sessions became a supported workflow, the Kitty graphics protocol landed, and OSC 133 parsing gave it prompt-aware scrollback. 0.45.1 arrived eight days later to fix what that surface broke — SSH nested-session detection, OSC9 notifications misfiring against the OSC99 spec, and Kitty image clearing on stacked panes. The project is single-maintainer and funds itself through sponsorship.

◆ Where it's heading

The arc runs from platform reach to terminal semantics. 0.44.0 took the multiplexer to native Windows; 0.45.0 taught it to read shell protocol rather than relay bytes. The 0.45.1 fixes cluster entirely on the protocol work, which is the expected cost of parsing escape sequences other tools emit loosely. Notably, 0.45.1 also adds escape hatches — scroll_mode_sync and explicit_theme_hue — suggesting the new defaults were more opinionated than some users wanted.

◆ Prediction

Expect 0.45.x to keep converging on OSC parsing edge cases, and expect the prompt-aware scrollback from OSC 133 to be built on next — command-level history or output capture is the obvious payoff for parsing prompt boundaries at all.

5.0

Z-Wave JS v15.32.0 ships the findings of two full-codebase security reviews.

◆ Current state

v15.32.0 is the result of two security and correctness reviews of the whole codebase. No major issues were found, but it hardens S2, ESPHome, Transport Service and config parsing, caps firmware file sizes, limits outstanding S0 nonces and makes every firmware update stage abortable. ESPHome encryption keys no longer need manual URL encoding, and the release adds seven device config changes.

◆ Where it's heading

After a run of endpoint-grouping and controller-migration releases, the project spent a cycle on defensive hardening rather than features. Device config work continues alongside, now including endpoint grouping for more shutters. The development MCP server getting path restrictions shows the review reached tooling too.

◆ Prediction

Expect a v15.32.x patch for regressions from the hardening, then a return to device config and endpoint grouping work.
