|
||
|
|
|
||
|
|
<p>We released ASDF 2.000 on May 31st 2010,
|
||
|
|
ASDF 3.0.0 on May 15th 2013,
|
||
|
|
ASDF 3.1.2 on May 6th 2014.
|
||
|
|
Releases of ASDF 2 and now ASDF 3 have since then been included
|
||
|
|
in all actively maintained CL implementations that used to bundle ASDF 1,
|
||
|
|
plus many implementations that previously did not.
|
||
|
|
ASDF has been made to work with all actively maintained CL
|
||
|
|
implementations and even a few implementations that are <em>not</em>
|
||
|
|
actively maintained.
|
||
|
|
</p>
|
||
|
|
<p>Furthermore, it is possible to upgrade from ASDF 1 to ASDF 2 or ASDF 3 on the fly
|
||
|
|
(though we recommend instead upgrading your implementation or replacing its ASDF module).
|
||
|
|
For this reason, we have stopped supporting ASDF 1 and ASDF 2.
|
||
|
|
If you are using ASDF 1 or ASDF 2 and are experiencing any kind of issues or limitations,
|
||
|
|
we recommend you upgrade to ASDF 3
|
||
|
|
— and we explain how to do that. See <a href="Loading-ASDF.html">Loading ASDF</a>.
|
||
|
|
</p>
|
||
|
|
<p>Note that in the context of compatibility requirements,
|
||
|
|
ASDF 2.27, released on Feb 1st 2013, and further releases up to 2.33,
|
||
|
|
count as pre-releases of ASDF 3, and define the <code>:asdf3</code> feature,
|
||
|
|
though the first stable release of ASDF 3 was release 3.0.1.
|
||
|
|
Significant new or improved functionality were added in ASDF 3.1;
|
||
|
|
the <code>:asdf3.1</code> feature is present in recent enough versions to detect this functionality;
|
||
|
|
the first stable release since then was ASDF 3.1.2.
|
||
|
|
New <code>*features*</code> are only added at major milestones,
|
||
|
|
and the next one will probably be <code>:asdf3.2</code>.
