What's New

Newer release adds OpenTelemetry tracing, shared daemon providers, and safer lockfile management, removing the experimental pkgx backend.

Breaking Changes

Experimental `pkgx:` backend has been removed.
Locked tools no longer switch backends automatically.
TOML inline commands replace file tasks.
`mise generate tool-stub --lock` requires a project config.
Dotfiles `include`/`exclude` require current mise on every machine.

New Features

OpenTelemetry export for tasks (experimental).
Shared daemon providers for PostgreSQL, CockroachDB, and NATS.
`mise backends switch` command for manual migration.
Declarative dotfile removal via `mode = 'absent'`.
`mise search` checks package registries.

Improvements

Safer lockfiles with `mise lock --bump` version confirmation.
Declarative cleanup via `remove_empty` templates and permissions-only entries.
Windows user service fixes for shell metacharacters.
.miserc.local.toml for per-checkout early configuration.
`mise ls` supports backend filtering with `-b` flag.

Bug Fixes

Windows user service fixes for shell metacharacters.
