THIS PAGE IS UNDER CONSTRUCTION!
These release notes list the enhancements and other changes contained in Model 204 version 8.0, which is still in development. Until the commercial release of the software, Rocket reserves the right to add to, remove, or change anything described herein.

==Overview==
These release notes contain installation and features information for the Rocket Model 204 version 8.0 release. Before beginning your installation, please read through this information about product installation and changes.

==New in this release==

==Operating system and hardware requirements==

===Operating system requirements===

===Hardware requirements===

===Connect★ compatibility with Model 204===

==SOUL (User Language) enhancements==

==External Call Facility enhancements==

==System enhancements==

==Editor enhancements==

==AUDIT204 enhancements==

==Recovery enhancements==

==Security enhancements==

==Janus product enhancements==

===TLS 1.3 support===
Janus SSL ports now support TLS 1.3 (RFC 8446) for both client and server connections. TLS 1.3 provides improved security and performance over TLS 1.2, including a simplified handshake with fewer round trips, and the removal of legacy features such as renegotiation.

The following TLS 1.3 cipher suites are supported:
<ul>
<li><code>TLS_AES_128_GCM_SHA256</code></li>
<li><code>TLS_AES_256_GCM_SHA384</code></li>
</ul>

Key exchange is performed using X25519 (Curve25519 Elliptic Curve Diffie-Hellman, per RFC 7748). Certificate authentication uses RSA-PSS signatures.

Key derivation uses the HKDF-based key schedule defined in RFC 8446, replacing the PRF-based approach of earlier TLS versions.

TLS 1.3 is enabled by default on ports that allow TLS 1.2. To restrict a port to earlier protocol versions, use the existing <var>SSLVERSION</var> parameter on the <var>[[JANUS DEFINE]]</var> command.

===Imagine Transparency support===
A new facility called [[Imagine Transparency]] is now available to allow files in an <var class="product">Imagine</var> database to be accessed from <var class="product">Model 204</var> as if they were native files.

A new port type, [[JANUS_DEFINE#IMAGINET|IMAGINET]], is now available. It allows <var class="product">Model 204</var> files to be stored on an Imagine server rather than in operating system files. A new parameter is now available on the [[DEFINE DATASET command#IMAGINE|ALLOCATE]] command to indicate that a file is to be accessed via the <var>IMAGINET</var> port rather than from operating system files.

==Debugger enhancements==

==Performance enhancements==

===Hardware-accelerated deflate/inflate compression===
The SOUL compression functions (<var>Deflate</var>, <var>Inflate</var>, <var>Gzip</var>, <var>Gunzip</var>, <var>Zip</var>, and <var>Unzip</var>) now exploit the IBM z15 (and above) DFLTCC (Deflate Conversion Call) hardware instruction when available. This provides significant performance improvement for compression and decompression of longstrings without any application code changes.

Hardware acceleration is used automatically when the processor supports it. On processors without DFLTCC support, the existing software implementation continues to be used transparently.

The DFLTCC instruction handles both the deflate (compress) and inflate (expand) operations natively in hardware, including CRC-32 computation, providing throughput improvements that scale with data size.

Release notes for Model 204 version 7.9 (Beta)

Gwalter — Tue, 09 Jun 2026 19:04:16 GMT

Gwalter moved page Release notes for Model 204 version 7.9 (Beta) to Release notes for Model 204 version 7.9

New page

==Overview==
These release notes contain installation and features information for the Rocket Model 204 version 7.9 release.
Before beginning your installation, please read through this information about product installation and changes.

==New in this release==
===Regular expression engine enhancements===

The [[Regex processing|regular expression engine]] can now produce traces of regular expression processing to help debug and optimize regular expressions. There are new user parameters [[REGEXTR parameter|REGEXTR]] and [[MREGEXTR parameter|MREGEXTR]], as well as a new [[Regex_processing#Common_regex_options|"t" option]] on regex method and $function invocations to control this tracing.


The regular expression engine now supports [https://www.regular-expressions.info/backref.html back references]. The following illustrates the use of a back reference (\1 in the example) to display all lines in procedure FOO where the left side of an assignment also appears on the right side. Note that this example is somewhat simplistic in that it it doesn't account for continuation lines and might not be what one wants if the left side of an assignment is an object member or array element.

b

%i is float
%sl is object stringlist

%sl = new
$procopn("FOO", "FOOPROC")
%sl:appendOpenProcedure

%i = 1
repeat while %i le %sl:count
%i = %sl:regexLocate("(%[a-z._$]+) *=.*\1", %i, options="i")
if %i eq 0 then loop end; end if
print %ls(%i)
%i = %i + 1
end repeat

end

===New Regex class===

Regular expressions can now be compiled into [[Regex class|Regex objects]]. This can be useful in allowing the compilations of dynamically generated regular expressions to be reused without recompilation. There is a new system parameter, [[REGXSTBL parameter|REGXSTBL]] that controls how much STBL space is to be reserved for each <var>Regex</var> object.


===New HDRCTL setting for DAEMONS===

Prior to V7.9, daemons did not output header lines.
Starting with V7.9, HDRCTL may be set to 8 to force daemons to output header lines.

===New MSGCTLU command to allow message changes by non-managers===

Message behavior may now be changed by non-managers effecting the user's thread only.
For instance, anyone may now produce a snap on a specific message within their thread which does not affect anyone else.
See [[MSGCTLU_command|MSGCTLU]] command for more details.

==System Enhancements==
===EAV support for SIRTUNED===

==Debugger enhancements==
Enhancements have been made for debugging applications that use IMAGEs to all of Model 204 debuggers (Janus Debugger, Tn3270 Debugger and SoftSpy).

==Performance enhancements==
===Regex Rewrite===

The [[Regex processing|regular expression engine]] has been completely rewritten to make it significantly faster. Tests indicate simple regex is at least three times as fast as the earlier regular expression engine, and 10 times or more faster for more complex regular expressions. In addition, constant regular expressions are now compiled when the containing procedure is compiled to eliminate the runtime cost of regular expression compilation and to detect errors in regular expressions at SOUL compile-time lather than evaluation time.

===ATB Storage Usage Greatly Increased===
Many more M204 data structures can be placed in ATB storage with 7.9. Probably the most important of these is the Push Down List (PDL).

==New and changed messages==

See [[New and updated messages in Model 204 version 7.9|New and updated messages in Model 204 version 7.9]] for details.
