Changes in version 0.3.0 (2026-08-30)                  

  - Restricted package to syntactically valid R package names. It now
    names only the package that owns the managed local copies;
    underscores, hyphens, and other identifiers are rejected.
  - Added a fixed stow subdirectory beneath each package-specific user
    data directory. Existing copies stored directly in the package
    directory are not discovered at the new location and may need to be
    downloaded again.
  - Replaced prior storage terminology with managed local copy
    terminology to reflect that files are stored as durable package data
    for reliable offline use.

                        Changes in version 0.2.0                        

  - Prevented pruning and removal from following symlinked directories
    or resolving managed-local-copy symlinks to targets outside the
    selected directory.
  - Added stow_prune() for package-aware removal of aged, superseded
    ETag variants and orphaned stow temporary/backup files. Conservative
    defaults retain the non-ETag copy, the newest ETag fallback, recent
    files, and recovery backups whose destination is missing; dry runs
    and explicit additional protections are supported.
  - Added stow_remove() for explicit, URL-scoped removal of the current
    managed local copy and all of its ETag variants without removing
    unrelated files.

                        Changes in version 0.1.0                        

  - Initially accepted identifiers broader than valid R package names.
  - Switched URL-directory and ETag filename keys from 32-bit to 64-bit
    xxHash values to make accidental filename collisions negligible.
  - Defaulted the package argument of stow(), stow_path(), and
    stow_info() to "stow" for direct use while retaining separate
    package directories.
  - Added stow() for ETag-aware downloads, offline lookup, optional
    validation, and staged updates.
  - Added stow_path() and stow_info() for locating and inspecting
    durable local copies in platform-appropriate user data locations.
