<pořadí>14</pořadí>
<text xmlns="http://www.w3.org/1999/xhtml">
<p>
Releases before v1.0.0 are development and are not intended for production use.
Releases after v1.0.0 should follow the rules of <a href="http://semver.org/">Semantic versioning</a>.
</p>
<p>
Released versions are described on the <m:a href="download">download</m:a> page.
</p>
<h2>v0.17, v0.18, v0.19 etc.</h2>
<p>
Releases for discussion and verification of the format and API design.
</p>
<h3>Data types</h3>
<ul>
<li>fractions</li>
<li>arrays/streams of bytes (octets)</li>
<li>arrays of other types</li>
<li>arrays of other types with support for NULL values</li>
<li>nested relations</li>
<li>date and time</li>
<li>floating-point numbers (IEEE 754)</li>
<li>support NULL values (introduce bitmaps)</li>
<li>support long strings (chunked, similar to octet streams)</li>
<li>fixed size integers</li>
<li>precise BigDecimal</li>
<li>string in UTF-16</li>
<li>string in ASCII</li>
<li>string in ISO 8859-1</li>
<li>string in ISO 8859-2</li>
</ul>
<h3>Inputs</h3>
<p>Probably no new ones before v1.0.0.</p>
<h3>Transformations</h3>
<ul>
<li>relpipe-tr-streamlet: based on the same interface as used by --streamlet in relpipe-in-filesystem</li>
</ul>
<h3>Outputs</h3>
<p>Probably no new ones before v1.0.0.</p>
<h3>Other tasks</h3>
<ul>
<li>publish documentation of the stable API and file format</li>
<li>publish automated complex tests (specification vs. implementation compliance)</li>
<li>verify the format from the performance point of view</li>
<li>improve parsing (corrupted input may currently lead to huge memory allocations), more fuzzing</li>
<li>code clean-up and refactoring, move some reusable parts to common libraries</li>
<li>test the build with another compiler and tune the code</li>
<li>pkg-config: version numbers, debug vs. release</li>
<li>packaging for Guix SD and .deb and .rpm distributions, Snapcraft, Flatpak etc.</li>
</ul>
<h2>v1.0</h2>
<p>
First version for production use.
Brings no new features, just stabilized result of previous development.
Stable must be:
</p>
<ul>
<li>format specification</li>
<li>relpipe-lib-writer</li>
<li>relpipe-lib-reader</li>
<li>relpipe-in-cli</li>
<li>relpipe-out-tabular</li>
<li>relpipe-in-xml</li>
<li>relpipe-out-xml</li>
<li>relpipe-in-csv</li>
<li>relpipe-out-csv</li>
<li>relpipe-out-ods</li>
</ul>
<p>
Other parts might be released as stable later.
</p>
<p>
After this point, all components (the format specification, particular libraries and particular tools)
will be versioned independently and the compatibility matrix will be maintained.
</p>
<h2>Further versions</h2>
