RKTools 7.7 is commercially available in July, 2017.
<p>
The main features in this release are summarized below and described in greater detail in the [[Release notes for RKTools V7.7]].</p>
 
===Web interface===
<p>
New in version 7.7 is [[RKWeb]], an easy-to-use web interface for managing the entire Model 204 environment. The RKWeb tools framework provides a highly productive web interface to common Model&nbsp;204 functionality.</p>
<p>
RKWeb is mobile-ready and provides a task-based UI for SOUL application development. Using RKWeb utilities, you can:</p>
<ul>
<li>Build applications</li>
<li>Manage SOUL code, passwords, groups, and SSL Certificates</li>
<li>Monitor performance</li>
</ul>
<p>
RKWeb also includes a journal scanner, command interface, and readers for [[SirTune]] reports and [[SirFact]] dumps.</p>
 
===Ease of installation===
<p>
As of version 7.7, all code for all Rocket-provided, SOUL-based products and utilities resides in the M204PROC file. This includes all the [[Dictionary/204 overview|Dictionary/204]] components (SUBSYSMGMT, FILEMGMT, etc.), all the [[SQL Server overview|SQL Server]] support code, and all code for the former UL/SPF products such as [[SirPro]], [[SirMon]], and [[SirScan]].</p>
 
===Security===
<p>
In version 7.7, JANSSL ([[Janus Network Security]]) is integrated with the other components in the RKWeb interface. Its operation is the same as before, and it is available without RKWeb from a Janus port as before. </p>
<p>
V7.7 JANSSL also includes support for SHA2 SSL Certificates, including SHA384.</p>
 
===Integration of Dictionary/204===
<p>
As of version 7.7, Dictionary/204 is integrated into RKTools, and it is accessible through both the RKTools and RKWeb interfaces, as well as from the Model 204 command line as before.</p>
 
===SQL Server utilities===
<p>
As of RKTools 7.7, the RKWeb interface makes available the [[SQL catalog#Using the SQL catalog|SQL Server]] Table Specification facility (TSF) and the catalog reporting utility (CCACATREPT).</p>
 
===Downloading instructions===
<p>
To download RKTools version 7.7:</p>
<ol>

==Janus/TN3270 Debugger Build 66 and 67==
<div class="mw-collapsible-content">
On July 5, 2017, Build 67 of the Janus/TN3270 Debugger Client was released. 
On April 3, 2017, Build 66 was released.
 
When Build 66 is used with Model&nbsp;204 version 7.7, you can configure automatic creation of a new Client log file on a daily basis to prevent excessive growth of the log. You can also turn logging off.
 
Build 67 lets you specify how many days worth of previous Client logs to retain. The new daily log is always named <code>log.txt</code>; the names of previous daily logs include their creation dates.
 
Build 67 also lets you relocate and optionally rename the installed default locations of the Debugger Client Help file, its PDF-file representation, or both.
 
See the Debugger <var class="book">[[Media:JdebugrNew.pdf|User's Guide]]</var> for details (Builds 66 and 67 in the "Release Notes" chapter).
