<p>Binary wheels are now provided for Linux on 64-bit ARM, intended for
Raspberry Pi. Installing <a class="reference internal" href="install_linux.html#linux-dep-apt"><span class="std std-ref">dependencies from system packages</span></a> is recommended.</p>

<section id="dependency-requirements">
<h4>Dependency requirements<a class="headerlink" href="#dependency-requirements" title="Link to this heading">¶</a></h4>
<p>Numpy 2.0 is now fully supported. Several deprecations and errors
using 2.0 were fixed.</p>
<p>Numpy and f2py are no longer required to build SpacePy. This change
will not be noticable to most users. Binary wheels are no longer tied
to numpy or Python version. SpacePy will now build on numpy 1.26 and
later on Python 3.12. Numpy is still required to run SpacePy.</p>
<p>Sphinx 4.0 is now required to build the documentation; this is not
a concern for most users.</p>
<p>Support for Python 3.6 has been removed due to inability to
test. Python 3.7 is the oldest supported Python; as a result, Astropy
2.0 is the oldest supported Astropy (if using Astropy).</p>

<h4>Deprecations and removals<a class="headerlink" href="#deprecations-and-removals" title="Link to this heading">¶</a></h4>
<p><a class="reference internal" href="autosummary/spacepy.toolbox.html#spacepy.toolbox.timeout_check_call" title="spacepy.toolbox.timeout_check_call"><code class="xref py py-obj docutils literal notranslate"><span class="pre">timeout_check_call</span></code></a> is deprecated as redundant to using

<p>The <code class="docutils literal notranslate"><span class="pre">spacepy.irbempy.irbempylib</span></code> module has been removed. This was
the old internal interface to the IRBEM library and was not intended
for public use.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">data_assimilation</span></code>, <code class="docutils literal notranslate"><span class="pre">radbelt</span></code>, and <code class="docutils literal notranslate"><span class="pre">spacepy_EnKF</span></code> modules
have been moved to the “sandbox”. These modules were undertested and
minimally documented. They may be restored in the future with
appropriate testing and docs.</p>

<h4>Other changes<a class="headerlink" href="#other-changes" title="Link to this heading">¶</a></h4>
<p>Operations on <a class="reference internal" href="autosummary/spacepy.datamodel.dmarray.html#spacepy.datamodel.dmarray" title="spacepy.datamodel.dmarray"><code class="xref py py-obj docutils literal notranslate"><span class="pre">dmarray</span></code></a> which return a scalar value
will now return a numpy <a class="reference external" href="https://numpy.org/doc/stable/glossary.html#term-array-scalar" title="(in NumPy v2.1)"><span class="xref std std-term">array scalar</span></a> rather than the base
Python type. This is consistent with the behavior of <a class="reference external" href="https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html#numpy.ndarray" title="(in NumPy v2.1)"><code class="xref py py-obj docutils literal notranslate"><span class="pre">ndarray</span></code></a>.
<a class="reference internal" href="autosummary/spacepy.datamodel.dmarray.html#spacepy.datamodel.dmarray" title="spacepy.datamodel.dmarray"><code class="xref py py-obj docutils literal notranslate"><span class="pre">dmarray</span></code></a> also supports assigning to its <code class="docutils literal notranslate"><span class="pre">dtype</span></code>
and <code class="docutils literal notranslate"><span class="pre">shape</span></code>. Together these changes should make <code class="docutils literal notranslate"><span class="pre">dmarray</span></code> a much
closer drop-in replacement for <a class="reference external" href="https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html#numpy.ndarray" title="(in NumPy v2.1)"><code class="xref py py-obj docutils literal notranslate"><span class="pre">ndarray</span></code></a>; in particular, these
address known issues with conversion to masked arrays and passing to
<a class="reference external" href="https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.pcolormesh.html#matplotlib.pyplot.pcolormesh" title="(in Matplotlib v3.9.2)"><code class="xref py py-obj docutils literal notranslate"><span class="pre">pcolormesh</span></code></a>.</p>
<p>Warnings issued by SpacePy are now associated with the line of the
calling code, not with the SpacePy code itself. The
<code class="docutils literal notranslate"><span class="pre">enable_deprecation_warning</span></code> <a class="reference internal" href="configuration.html"><span class="doc">configuration option</span></a>
has been removed and SpacePy does not force display of deprecation
warnings, as warnings issued by SpacePy cannot be distinguished from
other warnings. It is recommended to occasionally run Python code with
the <a class="reference external" href="https://docs.python.org/3/using/cmdline.html#cmdoption-W" title="(in Python v3.13)"><code class="xref std std-option docutils literal notranslate"><span class="pre">-Wd</span></code></a> option to enable deprecation warnings. See
<a class="reference external" href="https://docs.python.org/3/library/warnings.html#module-warnings" title="(in Python v3.13)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">warnings</span></code></a> for more details.</p>

<p>This release marks the end of all support for Python 2. SpacePy now
requires Python 3.6 or later. Minimum supported versions for other
dependencies were also increased; see <a class="reference internal" href="#release-0-5-0-deps"><span class="std std-ref">Dependency requirements</span></a> for details.</p>
<p>The SpacePy team now delivers binary wheels for all supported Python
versions (3.6-3.12) for 64-bit Windows, Linux, and Mac. Most users
will not need to build SpacePy; see <a class="reference internal" href="install.html"><span class="doc">Installing SpacePy</span></a> for details.</p>
<p>Due to changes in f2py, SpacePy 0.5.0 will not build on Python 3.12
with numpy 1.26 or later. It will, however, run fine. The SpacePy team
provides binary wheels for Mac and Windows. Users who wish to build
from source on Python 3.12 should first install numpy (which will
likely be built from source):</p>

<p>Not all dependencies are required for all functionality; see
<a class="reference internal" href="dependencies.html"><span class="doc">SpacePy Dependencies</span></a> for full details, including what functionality is
lost if a dependency is not installed.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">setup.py</span></code> based install process is no longer supported; as such,
<code class="docutils literal notranslate"><span class="pre">pip</span></code> and <code class="docutils literal notranslate"><span class="pre">setuptools</span></code> are now required. <code class="docutils literal notranslate"><span class="pre">wheel</span></code> is required if
building from source. The vast majority of modern Python distributions
already have these requirements.</p>
<p>Installing from <code class="docutils literal notranslate"><span class="pre">pip</span></code> normally installs all necessary dependencies.</p>
<p>The minimum supported version of all dependencies was updated in
SpacePy 0.5.0. Minimum versions are:</p>
<blockquote>
<div><ul class="simple">
<li><p>CPython 3.6</p></li>
<li><p>AstroPy 1.0</p></li>
<li><p>CDF 3.5</p></li>
<li><p>dateutil 2.1</p></li>
<li><p>h5py 2.10</p></li>
<li><p>matplotlib 3.1</p></li>
<li><p>numpy 1.15.1</p></li>
<li><p>scipy 1.0</p></li>
</ul>
</div></blockquote>
<p>The only supported compiler is the GNU gfortran compiler, aka
“gnu95”. Support for the older g77 compiler, as well as the Portland
Group and Intel compilers, has been removed.</p>

<h4>Other changes<a class="headerlink" href="#id40" title="Link to this heading">¶</a></h4>
<p>Data sources for leapsecond files and <a class="reference internal" href="autosummary/spacepy.omni.html#module-spacepy.omni" title="spacepy.omni"><code class="xref py py-mod docutils literal notranslate"><span class="pre">omni</span></code></a> Qin-Denton
files have been updated to provide current sources. If present,
entries in the <a class="reference internal" href="configuration.html"><span class="doc">configuration file</span></a> will still be
used instead. A (configurable) warning is issued for out-of-date leapsecond
files.</p>
<p>The representation of leap second intervals in time systems which
cannot directly represent them has been changed. Formerly times such
as 2008-12-31T23:59:60 were represented in e.g. UTC datetime as the
the beginning of the next day, e.g. 2009-01-01T00:00:00. They are
now represented by the last possible moment of the same day, e.g.
2008-12-31T23:59:59.999999. Fractional leapsecond counts are now rounded
to the integer instead of truncated; this rounding is applied to the total
TAI - UTC quantity not the individual increments of leap seconds. E.g
successive 0.2, 0.2, 0.2 leap seconds will result in 0, 0, and 1 new
leap seconds.</p>
<p>Similarly, leap seconds are now included in the fractional day
calculation of MJD, so MJD values around a leap second may be different
than in previous versions of SpacePy.</p>
<p>Most time systems are now converted to/from TAI rather than using
datetime. This may cause small differences with previous versions of
SpacePy, on order of a double precision. RDT and JD are particularly
affected for dates in the modern era. Time conversions around
leapseconds may also be different; in many cases they were undefined
in previous versions.</p>
