    o (2.99.1) Soft failure for if HEAD does not work. Will still download and
    add to cache without caching information. Additionally fix bug so config can
    be passed down to HEAD call from bfcneedsupdate, bfcadd, and bfcrpath.

    o (2.99.4) Fix bug to pass proxy down to HEAD call

NEW FEATURE

    o (2.99.2) Add progress argument to bfcadd/bfcdownload to control if a
    progress bar is displayed during an interactive session

CHANGES IN VERSION 2.7
----------------------

USER VISIBLE CHANGE

    o (2.7.1) Remove rappdirs officially from package after deprecating
    functionality and moving to using default R tools caching location.

BUG FIX

CHANGES IN VERSION 2.5
----------------------

ENHANCEMENT

    o (2.5.2) Add option to override unique identifer when adding files to the

ENHANCEMENT

    o (2.3.4) Add instructions for a shared cache across multiple users of a system
    o (2.3.2) Add direct SQL calls for certain retrieval functions to speed up

    function tha utilized the underlying .sql_get_field, .get_all_rids or
    .get_all_web_rids.
    o (2.3.1) Add @LTLA solution for making bfcrpath thread safe

CHANGES IN VERSION 2.1
----------------------

MAJOR UPDATES

    o (2.1.1) Change caching location warning/deprecation to an ERROR in
    preparation for removal of dependency next release.

CHANGES IN VERSION 1.99
----------------------

MAJOR UPDATES

    o (1.99.0) The default caching location has changed. Instead of
    rappdirs::user_cache_dir using tools::R_user_dir. To avoid conflicting
    caches, a user will have to manage an old cache location before
    proceeding. Information for handling an old cache location is provided in
    the vignette.
    o (1.99.0) Another major change, a default caching location is automatically
    created in a non interactive session instead of using a temporary
    location. In an interactive session, a user is still prompted for
    permission.
    o (1.99.0) An enviornment variable may be set system wide or user wide to
    control the default caching location: BFC_CACHE. Note: do not use R
    variables or command line export to set this variable. It must be set system
    wide or user wide for reproducibility in future R sessions or else it must
    be specified upon ever usage. It must be set before calling
    library(BiocFileCache) to take effect.
    o (1.99.0) Fixes partial argument matching error in SQL function SQLExecute
    o (1.15.1) Added file locking for thread-safe SQL operations. Thanks for the PR @LTLA

BUG FIX

    o (1.99.6) cleanbfc() incorrect format string; see
    https://github.com/Bioconductor/BiocFileCache/issues/31

CHANGES IN VERSION 1.11
----------------------

BUG FIX

    o (1.11.5) Update dplyr functions for dplyr_1.0.0 release 
    o (1.11.2) Fixes run of examples. Different result manual vs interactive so
    have conditional that will allow complete example if run by user rather than
    run automatically through the checks. 

NEW FEATURES

    o (1.11.1) Add makeCachedActiveBinding(). Allows data to be cached during
    ActiveBinding call. Avoids callback function executing data retrieval
    everytime.

    o (1.11.3) Only asks for / reports use of temporary cache once per
    session. https://github.com/Bioconductor/TENxBrainData/issues/7

CHANGES IN VERSION 1.7
----------------------

BUG FIX

    o (1.7.10) Fix date comparison to use as.POSIXlt instead of as.Date. This
    catches the rare edge case if a remote resource is updated twice in a day
    and a download happened in between the two.
    o (1.7.9) Make creation of database atomic commits
    o (1.7.8) Make adding resource to database atomic commits
    o (1.7.4) Limit where possible opening database in RW mode. Use read-only
    mode whereever possible to avoid database locking
    o (1.7.2) Fix bug in multi path addition through bfcadd/bfcrpaths. The
    function was assuming all files had same rtype and action. Now can
    vectorize
    o (1.7.1) Fix man documentation example. Interactive vs non interactive
    session

CHANGES IN VERSION 1.5
----------------------

BUG FIX

    o (v. 1.5.2) bfcrpath() more robust when adding regular expression
      rnames.

USER-VISIBLE CHANGES

    o (v. 1.5.4) bfcpath() implementation change. Only displays rpath and can
    work with multiple rids. bfcpath only for rpath access while bfcrpath is the
    option to get or add.

----------------------

NEW FEATURES

    o (v. 1.3.35) Save a post download processed file to cache.

    determine if local version of file is current
    o (v. 1.3.16) importbfc to load output of exportbfc
