Add NOTICE and inst/NOTICE

• Add files NOTICE and inst/NOTICE to more explicitly credit code included from other open source projects. (Previously drake only took a decentralized approach: comments in the source to indicate the project, package, and GitHub link (if available) to any code borrowed.)

Level separation

New features

• Add a new level_separation argument to vis_drake_graph() and render_drake_graph() to control the aspect ratio of visNetwork graphs (#1303, @matthewstrasiotto, @matthiasgomolka, @robitalec).

Nomenclature

Version 7.12.7

• Deprecate caching = "master" in favor of caching = "main".

Safeguards and worker logs

Bug fixes

• Sanitize empty symbols in language columns (#1299, @odaniel1).
• Handle cases where NROW() throws an error (#1300, julian-tagell on Stack Overflow).
• Prohibit dynamic branching over non-branching dynamic files (#1302, @djbirke).

• Expose the log_worker argument of clustermq::workers() to make() and drake_config() (#1305, @billdenney, @mschubert).
• Set as.is to TRUE in utils::type.convert() (#1309, @bbolker).

CRAN hotfix

Fixes a documentation-related warning in the last submission (7.12.3).

Lockfile bugfix and better-looking graphs

Version 7.12.3

Bug fixes

• cached_planned() and cached_unplanned() now work with non-standard cache locations (#1268, @plebejer).
• Set use_cache to FALSE more often (#1257, @plebejer).
• Use namespaced function calls in mtcars example instead of loading packages.
• Replace the iris dataset with the airquality dataset in all documentation, examples, and tests (#1271).
• Assign functions created with code_to_function() to the proper environment (#1275, @robitalec).
• Store tracebacks as character vectors and restrict the contents of error objects to try to prevent accidental storage of large data from the environment (#1276, @billdenney).
• Strongly depend on tidyselect (#1274, @dernst).
• Avoid txtq lockfiles (#1232, #1239, #1280, @danwwilson, @pydupont, @mattwarkentin).

New features

• Add a new drake_script() function to write _drake.R files for r_make() (#1282).

Enhancements

• Deprecate expose_imports() in favor of make(envir = getNamespace("yourPackage") (#1286, @mvarewyck).
• Suppress the message recommending r_make() if getOption("drake_r_make_message") is FALSE (#1238, @januz).
• Improve the appearance of the visNetwork graph by using the hierarchical layout with visEdges(smooth = list(type = "cubicBezier", forceDirection = TRUE)) (#1289, @mstr3336).

Important reproducibility bugfix for dynamic branching

Bug fixes

• Invalidate old sub-targets when finalizing a dynamic target (@richardbayes). Solves a major reproducibility bug (#1260).
• Prevent splice_inner() from dropping formal arguments shared by c() (#1262, @bart1).

Fully custom target names in static branching

Version 7.12.1

Bug fixes

• Repair subtarget_hashes.cross() for crosses on a single grouping variable.
• Repair dynamic group() used with specialized formats (#1236, @adamaltmejd).
• Enforce tidyselect >= 1.0.0.

New features

• Allow user-defined target names in static branching with the .names argument (#1240, @maciejmotyka, @januz).

Enhancements

• Do not analyze dependencies of calls to drake_plan() (#1237, @januz).
• Error message for locked cache gives paste-able error message in Windows (#1243, @billdenney).
• Prevent stack traces from accidentally storing large amounts of data (#1253, @sclewis23).

Mostly bug fixes and guard rails

Version 7.12.0

Bug fixes

• Ensure up-to-date sub-targets are skipped even if the dynamic parent does not get a chance to finalize (#1209, #1211, @psadil, @kendonB).
• Restrict static transforms so they only use the upstream part of the plan (#1199, #1200, @bart1).
• Correctly match the names and values of dynamic cross() sub-targets (#1204, @psadil). Expansion order is the same, but names are correctly matched now.
• Stop trying to remove file_out() files in clean(), even when garbage_collection is TRUE (#521, @the-Hull).
• Fix keep_going = TRUE for formatted targets (#1206).
• Use the correct variable names in logger helper (progress_bar instead of progress) so that drake works without the progress package (#1208, @mbaccou).
• Avoid conflict between formats and upstream dynamic targets (#1210, @psadil).
• Always compute trigger metadata up front because recovery keys need it.
• Deprecate and remove hasty mode and custom parallel backends (#1222).
• Compartmentalize fixed runtime parameters in config$settings (#965).

New features

• Add new functions drake_done() and drake_cancelled() (#1205).

Speedups

• Avoid reading build times of dynamic sub-targets in drake_graph_info() (#1207).

Enhancements

• Show an empty progress bar just before targets start to build when verbose is 2 (#1203, @kendonB).
• Deprecate the jobs argument of clean().
• Show an informative error message for empty dynamic grouping variables (#1212, @kendonB).
• Throw error messages if users supply dynamic targets to drake_build() or drake_debug() (#1214, @kendonB).
• Log the sub-target name and index of the failing sub-target in the metadata of the sub-target and its parent (#1214, @kendonB).
• Shorten the call stack in error metadata.
• Deprecate and remove custom schedulers (#1222).
• Deprecate hasty_build (#1222).
• Migrate constant runtime parameters to config$settings (#965).
• Warn the user if file_in()/file_out()/knitr_in() files are not literal strings (#1229).
• Prohibit file_out() and knitr_in() in imported functions (#1229).
• Prohibit knitr_in() in dynamic branching (#1229).
• Improve the help file of target().
• Deprecate and rename progress functions to avoid potential name conflicts (progress() => drake_progress(), running() => drake_running(), failed() => drake_failed()) (#1205).
