		<description><![CDATA[The development of the current generation of Logtalk, 2.x, began on January of 1998. At that time, the ISO Prolog Standard (Part 1: General Core) was only three years old. Thus, accepting and dealing with the lack of compliance of most Prolog compilers with the standard was a sensible choice.
Back to the present. The ISO [...]]]></description>

		<description><![CDATA[Currently, there are two approved ISO Prolog standards: ISO/IEC 13211-1: General core (first edition published in 1995-06-01; an errata was published recently) and ISO/IEC 13211-1: Modules (first edition published in 2000-06-01). There are also five standardization proposals being discussed: Core Revision, Definite Clause Grammars (DCGs), Globals, Threads, and Portable Operating-System Interface (POSI).

		<description><![CDATA[Recent Logtalk releases include a shell script, logtalk_select, which allows easy switching between installed Logtalk versions. It&#8217;s an experimental script, loosely based on the python_select script, with two major limitations: it doesn&#8217;t update the Logtalk user folder and it&#8217;s POSIX-only. Nevertheless, it&#8217;s useful whenever you want to test your application with a new Logtalk release. [...]]]></description>

In recent years, I found myself responsible for four different draft proposals: Core Revision, DCGs, Threads, and POSI (Portable Operating-System Interface). My fault really. With the exception of the DCGs proposal, all the other proposals are born from my initiative. Recently I have been unable [...]]]></description>
