With v46 Hot, shell-dep hot-swap --bin rg atomically replaces the binary pointer in your environment’s PATH cache. The change is visible to the very next line in your script.
The gains come primarily from the hot cache and parallel hot-swap verification. 🔥 Error: “Hot cache temperature too low” This happens if your /dev/shm is full or your system doesn’t support shared memory. Fix: shell dep version 46 hot
The core team has run v46 Hot in production at companies like ScaleCore and DataSiphon for six weeks. The cache subsystem is stable, and the hot swap logic has been fuzz-tested extensively. With v46 Hot, shell-dep hot-swap --bin rg atomically
export SHELL_DEP_HOT_CACHE_DIR=/tmp/shell-dep-hot This means the binary’s signature is older than the max_sig_age (default 30 days). It still works, but you’ll see a warning. To silence, increase the age limit in .shell-dep.toml : 🔥 Error: “Hot cache temperature too low” This
introduces a daemon-less shared memory cache. The first time you run a command, it builds a hot manifest in /dev/shm (or a Windows equivalent). Subsequent runs are almost instantaneous.
Released to the public registry earlier this quarter, shell-dep v46 (dubbed “Hot” by its core maintainers due to its aggressive caching layer and real-time resolution engine) is already being hailed as the most significant upgrade to shell-based dependency management in over two years. If you are still running v45 or—heaven forbid—v44, you are leaving performance, security, and readability on the table.
