What is Mamba?

Mamba is adding the reproducibility controls conda users have been asking of the solver.

The 2.9.0 release candidates introduce two user-facing controls: excluding builds newer than a given timestamp with --exclude-newer, and opting out of link script execution. Around them sit fixes with an operational bent, leaving permissions on shared package cache directories alone, explaining missing packages when string ids collide with solvables, and static linking corrections. The earlier alpha in this window is entirely bug fixes to noarch Python entry point linking and root package expansion.

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.

Mamba is adding the reproducibility controls conda users have been asking of the solver.

◆ Current state

The 2.9.0 release candidates introduce two user-facing controls: excluding builds newer than a given timestamp with --exclude-newer, and opting out of link script execution. Around them sit fixes with an operational bent, leaving permissions on shared package cache directories alone, explaining missing packages when string ids collide with solvables, and static linking corrections. The earlier alpha in this window is entirely bug fixes to noarch Python entry point linking and root package expansion.

◆ Where it's heading

Both new options point the same way: making an environment solve predictable and less trusting. A timestamp cutoff turns a solve into something reproducible after the fact, and disabling link scripts removes arbitrary code execution from installation. The bug fixes concentrate on shared and multi-user installs, which suggests the pressure is coming from environments where one package cache serves many users.

◆ Prediction

With a timestamp cutoff and a link-script opt-out both landing in the same release, the direction is toward solves that can be audited and repeated; further work most likely continues on the shared-cache and permissions handling these fixes keep touching.

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.
