Changes in version 0.2.0 (2026-04-28)                  

Breaking changes

This release removes implicit file writes to the user's filespace in
order to comply with CRAN policy. Several functions now require
arguments that previously defaulted to a location derived from other
inputs. Update call sites to pass these arguments explicitly.

create_batch_api() and create_batch_job()

  - path is now required. The previous default of "." (the working
    directory) has been removed.
  - Before: create_batch_api() wrote plumber.R to getwd().
  - After: callers must supply an explicit path, e.g.
    create_batch_api("path/to/api_directory").
  - Also fixes a bug where a path containing . (for example
    "~/api_directory/plumber.R") was silently rewritten to
    "./plumber.R". The user-supplied path is now respected.

abba_slurm_submit_job(), abba_rslauncher_submit_job_local(), abba_rslauncher_submit_logrx_job_local()

  - log_path is now required. There is no longer a default that writes
    the log next to the submitted program.
  - Before: omitting log_path caused the log to be written to
    dirname(program_path).
  - After: callers must pass log_path explicitly, e.g.
    abba_slurm_submit_job("/path/to/script.R", log_path =
    "/path/to/logs").
  - When using abba_submit_batch() with a Workbench or SLURM submit
    function, pass log_path through the ... arguments, e.g.
    abba_submit_batch(progs, submit_func =
    abba_rslauncher_submit_job_local, log_path = "/path/to/logs").

abba_submit_batch() and abba_submit_batch_and_get_results()

  - cache_folder is now required whenever update_cache = TRUE or
    rerun_unchanged_programs = FALSE. The previous fallback that wrote a
    .abba_cache directory next to each program has been removed.
  - Before: caching silently wrote to dirname(program_path)/.abba_cache.
  - After: callers must supply cache_folder explicitly or set it via the
    abba.default_cache_folder option. A clear error is raised if caching
    is requested without a cache_folder.
  - When update_cache = FALSE and rerun_unchanged_programs = TRUE (the
    defaults), no cache writes occur and no cache_folder is required.

Internal

  - Cache helper functions (cache_match(), abba_save_file_cache()) now
    require cache_folder and error clearly when it is missing. This also
    stops an existing code path from writing a cache into the program's
    directory when the top-level call did not request caching.

Documentation

  - Package Title and Description now quote external software names
    ('Kubernetes', 'SLURM', 'Posit Workbench') per CRAN conventions.
  - Examples and vignettes updated to show explicit paths for
    create_batch_*, log_path, and cache_folder rather than defaults.
  - The standalone LICENSE file has been removed; License in DESCRIPTION
    is now Apache License (>= 2) without the file LICENSE pointer, which
    is the correct form when there are no additional restrictions.
