Changes in version 0.5.0 (2024-06-12)                  

  - proj_trans() is no longer supported with list input, and returns
    matrix output.

  - PROJ >= 6 is now a hard dependency (#42)

  - Deprecate ok_proj6() (#42)

  - Add {wk} transformer api (#44, #46, #48, #50)

  - Replace proj_trans() with S3 generic (#56)

                 Changes in version 0.4.5 (2023-12-01)                  

  - New function proj_version().

  - reinstated proj function!

  - ok_proj6() is now meaningful again.

  - Deprecated old proj_trans_generic().

                 Changes in version 0.3.1 (2020-08-31)                  

  - New function 'proj_crs_text()' to convert from one CRS text format
    to another.

  - No set up on load now, all handled by libproj. Package should always
    function, always with version 7 or above.

  - FIXME: (should deprecate) Removed ok_proj6()

  - Now importing libproj, to provide cross platform access to PROJ
    version 7 and above and for configuration of metadata files.

  - Incorporated fixes and improvements from Dewey Dunnington.

                        Changes in version 0.2.0                        

  - Now using Github Actions to test linux, windows, macos. Many thanks
    to James Balamuta for guidance on how to do this.

  - The internal C functionality calling the PROJ library now uses .Call
    rather than .C. The .C function PROJ_proj_trans_generic() is now not
    used and will be removed.

  - On load behaviour has changed, on Windows and MacOS a check is made
    for a local copy of the proj/ PROJ data directory with metadata
    files. If this is present, the path to that folder is set using the
    underlying PROJ library function proj_context_set_search_paths().

This is only relevant to Windows and MacOS static builds, these are
self-contained, the R package contains the PROJ library and everything
it needs. Generally in other installations (brew on MacOS, apt install,
or from source builds on Linux) the PROJ library self-configures and
knows where to find this directory.

This is automatic for source builds on Windows which download pre-built
binaries and data from https://github.com/rwinlib, and so will be using
a given PROJ version.

On MacOS, this only occurs if configure options --with-data-copy=yes and
--with-proj-data=DIR are used. This is done manually on CRAN by admins.
The current version used can be found at
https://mac.r-project.org/libs-4/.

  - Need proj version 6.1.0 or above, and a configuration fix on MacOS
    for libsqlite thanks to Brian Ripley, and CRAN.

  - Fixed bug not returning transformed z or t.

  - Windows: update to proj 6.3.1

                 Changes in version 0.1.6 (2020-04-15)                  

  - We now use the PROJ::proj_trans internally, and just loop over
    vectors. (so proj_trans_generic is a misnomer, technically).

  - Prevent error on out of bounds values from proj_trans_generic(). We
    get Inf.

                 Changes in version 0.1.5 (2020-03-29)                  

  - Attempt to fix errors on CRAN, add missing test for functionality
    with required lib-proj version and use more generic initialization
    string.

  - New function [proj_create()] to generate CRS formats from various
    input types.

                 Changes in version 0.1.0 (2020-01-07)                  

  - Removed CPP variable from configure thanks to CRAN.

  - Sorted out .C registration.

  - Now set data directory for installed share files, thanks to Jeroen
    Ooms for the nudge in the right direction with the R API.

  - Cleaned up CI testing, so we get tested on versions 5, 6, and 7 of
    PROJ on travis.

  - Removed proj_trans(), only function is proj_trans_generic() more
    closely aligned to the API of PROJ itself (=> 6).

  - Included PROJ library tooling for Windows, thanks to Jeroen Ooms.

                     Changes in version 0.0.1.9001                      

  - Remove Rcpp.

                        Changes in version 0.0.1                        

  - R function proj_trans() gains a quiet argument to control output of
    warnings about missing values.

  - New C functions R_proj_trans_FWD() and R_proj_trans_INV() using the
    base R API. Interface is matrix in, matrix out always with three
    columns out as per reproj.

  - First working code with Rcpp function proj_trans_cpp().
