<h2>8.2.0 Release Notes<a class="headerlink" href="#id37" title="Permalink to this headline">¶</a></h2>
<p><em>November 1st 2021</em></p>
<section id="announcements">
<h3>Announcements<a class="headerlink" href="#announcements" title="Permalink to this headline">¶</a></h3>
<p>From PROJ 9.0.0 and onwards CMake will be the only build system bundled
with the PROJ package. As a consequence support for Autotools builds will
stop when the 8.2 branch of PROJ reaches end of life. We encourage
everyone to adjust their build workflows as soon as possible and report
any discrepancies discovered between Autotools and CMake builds.</p>
<p>Details about the build system unification can be found in <a class="reference internal" href="community/rfc/rfc-7.html#rfc7"><span class="std std-ref">PROJ RFC 7: Drop Autotools, maintain CMake</span></a>.</p>
<p>Note also that the “CMake: revise handling of symbol export and static builds”
change mentioned below may require changes for users of the library on Windows.</p>

<p>This requires changes for users of static builds on Windows that do not use CMake
config files. The empty <code class="docutils literal notranslate"><span class="pre">PROJ_DLL=</span></code> definition must now be defined when building
against a static build of PROJ.
For users of dynamic builds on Windows, the <code class="docutils literal notranslate"><span class="pre">PROJ_MSVC_DLL_IMPORT</span></code> definition is
no longer needed.</p>

<h2>7.0.0 Release Notes<a class="headerlink" href="#id342" title="Permalink to this headline">¶</a></h2>
<p><em>March 1st 2020</em></p>
<p>The major feature in PROJ 7 is significantly improved handling of gridded
models. This was implemented in <a class="reference internal" href="community/rfc/rfc-4.html#rfc4"><span class="std std-ref">PROJ RFC 4: Remote access to grids and GeoTIFF grids</span></a>.
The main features of the RFC4 work is that PROJ now implements a new grid format,
Geodetic TIFF grids, for exchanging gridded transformation models. In addition
to the new grid format, PROJ can now also access grids online using a data
store in the cloud.</p>
<p>The grids that was previously available via the proj-datumgrid packages are now
available in two places:</p>
<blockquote>
<div><ol class="arabic simple">
<li><p>As a single combined data archive including all available resource files</p></li>
<li><p>From the cloud via <a class="reference external" href="https://cdn.proj.org">https://cdn.proj.org</a></p></li>
</ol>
</div></blockquote>
<p>In Addition, provided with PROJ is a utility called <strong class="program">projsync</strong> that can be used
download grids from the data store in the cloud.</p>
<p>The use of the new grid format and the data from the cloud requires that
PROJ is build against <code class="docutils literal notranslate"><span class="pre">libtiff</span></code> and <code class="docutils literal notranslate"><span class="pre">libcurl</span></code>. Both are optional dependencies
to PROJ but it is highly encouraged that the software is build against both.</p>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>PROJ 7 will be last major release version that includes the <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code>
header. The functionality in <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code> is deprecated and only supported in
maintenance mode. It is inferior to the functionality provided by functions
in the <code class="docutils literal notranslate"><span class="pre">proj.h</span></code> header and all projects still relying on <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code> are encouraged
to migrate to the new API in <code class="docutils literal notranslate"><span class="pre">proj.h</span></code>. See <a class="reference internal" href="development/migration.html#api-migration"><span class="std std-ref">Version 4 to 6 API Migration</span></a>.

<h2>6.0.0 Release Notes<a class="headerlink" href="#id491" title="Permalink to this headline">¶</a></h2>
<p><em>March 1st 2019</em></p>
<p>PROJ 6 has undergone extensive changes to increase its functional scope from a
cartographic projection engine with so-called “early-binding” geodetic datum
transformation capabilities to a more complete library supporting coordinate
transformations and coordinate reference systems.</p>
<p>As a foundation for other enhancements, PROJ now includes a C++ implementation
of the modelisation propopsed by the ISO-19111:2019 standard / OGC Abstract
Specification Topic 2: “Referencing By Coordinates”, for geodetic reference
frames (datums), coordinate reference systems and coordinate operations.
Construction and query of those geodetic objects is available through a new C++
API, and also accessible for the most part from bindings in the C API.</p>
<p>Those geodetic objects can be imported and exported from and into the OGC
Well-Known Text format (WKT) in its different variants: ESRI WKT, GDAL WKT 1,
WKT2:2015 (ISO 19162:2015) and WKT2:2018 (ISO 19162:2018). Import and export of
CRS objects from and into PROJ strings is also supported. This functionality
was previously available in the GDAL software library (except WKT2 support
which is a new feature), and is now an integral part of PROJ.</p>
<p>A unified database of geodetic objects, coordinate reference systems and their
metadata, and coordinate operations between those CRS is now available in a
SQLite3 database file, proj.db. This includes definitions imported from the
IOGP EPSG dataset (v9.6.0 release), the IGNF (French national mapping agency)
geodetic registry and the ESRI projection engine database. PROJ is now the
reference software in the “OSGeo C stack” for this CRS and coordinate operation
database, whereas previously this functionality was spread over PROJ, GDAL and
libgeotiff, and used CSV or other adhoc text-based formats.</p>
<p>Late-binding coordinate operation capabilities, that takes metadata such as
area of use and accuracy into account, has been added. This can avoid in a
number of situations the past requirement of using WGS84 as a pivot system,
which could cause unneeded accuracy loss, or was not doable at all sometimes
when transformation to WGS84 was not available. Those late-binding capabilities
are now used by the proj_create_crs_to_crs() function and the cs2cs utility.</p>
<p>A new command line utility, projinfo, has been added to query information about
a geodetic object of the database, import and export geodetic objects from/into
WKT and PROJ strings, and display coordinate operations available between two
CRSs.</p>

<h2>PROJ 5.0.0<a class="headerlink" href="#proj-5-0-0" title="Permalink to this headline">¶</a></h2>
<p><em>February 1st 2018</em></p>
<p>This version of PROJ introduces some significant extensions and
improvements to (primarily) the geodetic functionality of the system.</p>
<p>The main driver for introducing the new features is the emergence of
dynamic reference frames, the increasing use of high accuracy GNSS,
and the related growing demand for accurate coordinate
transformations. While older versions of PROJ included some geodetic
functionality, the new framework lays the foundation for turning PROJ
into a generic geospatial coordinate transformation engine.</p>
<p>The core of the library is still the well established projection code.
The new functionality is primarily exposed in a new programming
interface and a new command line utility, <a class="reference internal" href="apps/cct.html#cct"><span class="std std-ref">cct</span></a>
(for “Coordinate Conversion and Transformation”). The old programming interface is
still available and can - to some extent - use the new geodetic
transformation features.</p>
<p>The internal architecture has also seen many changes and much
improvement. So far, these improvements respect the existing
programming interface. But the process has revealed a need to simplify
and reduce the code base, in order to support sustained active
development.</p>
<p><strong>Therefore we have scheduled regular releases over the coming years</strong>
<strong>which will gradually remove the old programming interface.</strong></p>
<p><strong>This will cause breaking changes with the next two major version</strong>
<strong>releases, which will affect all projects that depend on PROJ</strong>
<strong>(cf. section “deprecations” below).</strong></p>
<p>The decision to break the existing API has not been easy, but has
ultimately been deemed necessary to ensure the long term survival of
the project. Not only by improving the maintainability immensely, but
also by extending the potential user (and hence developer) community.</p>
<p>The end goal is to deliver a generic coordinate transformation
software package with a clean and concise code base appealing to
both users and developers.</p>

<p>For the first time in more than 25 years the major version number of
the software is changed. The decision to do this is based on the many
new features and new API. While backwards compatibility remains -
except in a few rare corner cases - the addition of a new and improved
programming interface warrants a new major release.</p>
<p>The new major version number unfortunately leaves the project in a bit
of a conundrum regarding the name. For the majority of the life-time
of the product it has been known as PROJ.4, but since we have now
reached version 5 the name is no longer aligned with the version
number.</p>
<p>Hence we have decided to decouple the name from the version number and
from this version and onwards the product will simply be called PROJ.</p>
<p>In recognition of the history of the software we are keeping PROJ.4 as
the <em>name of the organizing project</em>. The same project team also
produces the datum-grid package.</p>
<p>In summary:</p>
<ul class="simple">
<li><p>The PROJ.4 project provides the product PROJ, which is now at
version 5.0.0.</p></li>
<li><p>The foundational component of PROJ is the library libproj.</p></li>
<li><p>Other PROJ components include the application proj, which provides
a command line interface to libproj.</p></li>
<li><p>The PROJ.4 project also distributes the datum-grid package,
which at the time of writing is at version 1.6.0.</p></li>
</ul>

<h3>Updates<a class="headerlink" href="#id590" title="Permalink to this headline">¶</a></h3>
<ul>
<li><p>Introduced new API in <code class="docutils literal notranslate"><span class="pre">proj.h</span></code>.</p>
<blockquote>
<div><ul class="simple">
<li><p>The new API is orthogonal to the existing <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code> API and the internally used <code class="docutils literal notranslate"><span class="pre">projects.h</span></code> API.</p></li>
<li><p>The new API adds the ability to transform spatiotemporal (4D) coordinates.</p></li>
<li><p>Functions in the new API use the <code class="docutils literal notranslate"><span class="pre">proj_</span></code> namespace.</p></li>
<li><p>Data types in the new API use the <code class="docutils literal notranslate"><span class="pre">PJ_</span></code> namespace.</p></li>
</ul>
</div></blockquote>
</li>
<li><p>Introduced the concept of “transformation pipelines” that makes possible to do complex geodetic transformations of coordinates by daisy chaining simple coordinate operations.</p></li>
<li><p>Introduced <a class="reference internal" href="apps/cct.html#cct"><span class="std std-ref">cct</span></a>, the Coordinate Conversion and Transformation application.</p></li>
<li><p>Introduced <a class="reference internal" href="apps/gie.html#gie"><span class="std std-ref">gie</span></a>, the Geospatial Integrity Investigation Environment.</p>
<ul class="simple">
<li><p>Selftest invoked by <code class="docutils literal notranslate"><span class="pre">-C</span></code> flag in <a class="reference internal" href="apps/proj.html#proj"><span class="std std-ref">proj</span></a> has been removed</p></li>
<li><p>Ported approx. 1300 built-in selftests to <a class="reference internal" href="apps/gie.html#gie"><span class="std std-ref">gie</span></a> format</p></li>
<li><p>Ported approx. 1000 tests from the gigs test framework</p></li>
<li><p>Added approx. 200 new tests</p></li>
</ul>
</li>
<li><p>Adopted terminology from the OGC/ISO-19100 geospatial standards series. Key definitions are:</p>
<blockquote>
<div><ul class="simple">
<li><p>At the most generic level, a <em>coordinate operation</em> is a change of coordinates, based on a one-to-one relationship, from one coordinate reference system to another.</p></li>
<li><p>A <em>transformation</em> is a coordinate operation in which the two coordinate reference systems are based on different datums, e.g. a change from a global reference frame to a regional frame.</p></li>
<li><p>A <em>conversion</em> is a coordinate operation in which both coordinate reference systems are based on the same datum, e.g. change of units of coordinates.</p></li>
<li><p>A <em>projection</em> is a coordinate conversion from an ellipsoidal coordinate system to a plane. Although projections are simply conversions according to the standard, they are treated as separate entities in PROJ as they make up the vast majority of operations in the library.</p></li>

</li>
<li><p>New “free format” option for operation definitions, which permits separating tokens by whitespace when specifying key/value- pairs, e.g. <code class="docutils literal notranslate"><span class="pre">proj</span> <span class="pre">=</span> <span class="pre">merc</span> <span class="pre">lat_0</span> <span class="pre">=</span> <span class="pre">45</span></code>.</p></li>

<li><p>Added ITRF2000, ITRF2008 and ITRF2014 init-files with ITRF transformation parameters, including plate motion model parameters.</p></li>
<li><p>Added ellipsoid parameters for GSK2011, PZ90 and “danish”. The latter is similar to the already supported andrae ellipsoid, but has a slightly different semimajor axis.</p></li>

Checks if an operation has an inverse. Use this instead of checking whether <code class="docutils literal notranslate"><span class="pre">P->inv</span></code> exists, since that can no longer be relied on.</p></li>
<li><p>ABI version number updated to 13:0:0.</p></li>
<li><p>Removed support for Windows CE.</p></li>
<li><p>Removed the VB6 COM interface.</p></li>
