+<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>

+<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

+<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>

+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>

+<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>

+</div></blockquote>
+</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>

+<li><p>Introduced <code class="docutils literal notranslate"><span class="pre">pj_has_inverse()</span></code> function to <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code>. Checks if an operation has an inverse. Use this instead of checking whether <code class="docutils literal notranslate"><span class="pre">P-&gt;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>
