Summary

Dyalog has found defects in some of the code which has been optimised in 18.0. As a result of this Dyalog has decided to recommend that if you have not already upgraded to 18.0 and you do not urgently need the new features of 18.0 then you should skip 18.0 and wait for the subsequent release. Dyalog has therefore extended the support for 17.1 by an extra release cycle (typically a year). Given this extension we have also decided to release new installation images for 17.1 so that users can pick up all the fixes that have been applied to 17.1 thus far, both for the interpreter and all other parts of the product. More details can be found in the Dyalog blog at www.dyalog.com/blog/.

Issue 4 contains all the fixes and enhancements that have been made thus far to 17.1. Of particular note:

Documentation

We recommend that you read both the Release Notes and the dyalog_readme.

The Conga User Guide Supplement has now been merged into the main Guide; it is no longer included in 17.1 releases. The new Guide includes details of the changes to the Conga workspace. In particular you should use HttpCommand rather than the now-removed Samples.HTTPGet.
For example:
      )xload conga
      ]load HttpCommand
      html←(HttpCommand.Get'http://www.dyalog.com').Data
