In the descriptions below, $DYALOG is used to refer to the directory in which Dyalog APL is installed. This will vary depending
on which version of Dyalog APL you have installed, and on which operating system. If you have more than one version of Dyalog APL
installed then you will have to repeat the process for each applicable version.
Typical examples of the installation directory include:
C:\Program Files\Dyalog\Dyalog APL-64 13.2 Unicode
C:\Program Files (x86)\Dyalog\Dyalog APL 13.1 Classic
C:\Program Files\Dyalog\Dyalog APL 12.1 Unicode

20th August 2013
These fixes apply to 13.2 UNICODE only.
1.1.0.87 contains a number of enhancements and fixes over previous versions, including:
To install the patch, download the 32-bit or 64-bit zip file as appropriate. Unzip into a temporary directory and then copy the .dll and help directory into the Dyalog installation directory.
Note: Dyalog only supports the Array Editor with the Unicode edition of Dyalog APL 13.2 onwards for Windows. Visit www.davidliebtag.com for support for Classic editions and for other APL dialects. Note also that it may be necessary to unblock the new $DYALOG\help\dlaedit.chm file before you can see its contents. To do this, right click on the file in Windows Explorer and select Properties; the bottom-most button on the General tab will be "Unblock" if this has not already been done.
27th June 2013
These fixes apply to 13.2 only.
006199 An ambiguous match occurs while performing ⍒ or ⍋ on an array of GNU MP BigInts
This fix requires .NET support files with version 18249 or higher; these can be found at the bottom of this page.
20th June 2013

009580: If you cut some text from the beginning of the line, editor syntax colouring can go wrong
009581: Colours dialog box: background colour of the dfn guard doesn't change when you change Control Structure background colour
These fixes require new dyares*.dll files. Please download the zipfile appropriate to your edition of Dyalog APL:
To install, download the zip file appropriate to your edition of APL. Unzip the contents of the zip file (one file only) into a temporary directory, and then copy the dyares*.dll file into your Dyalog installation directory ($DYALOG).
24th April 2013
These fixes apply to 13.2 UNICODE only.
It is necessary only to update the 64 bit version of the Array Editor; however the 32 bit version is included for completeness' sake.
To install the patch, download the 32-bit or 64-bit zip file as appropriate. Unzip into a temporary directory and then copy the .dll and help
directory into the Dyalog installation directory.
Note: Dyalog only supports the Array Editor with the Unicode edition of Dyalog APL 13.2 for Windows. Visit www.davidliebtag.com for support for Classic editions and for other APL dialects.
19th March 2013
These fixes appear in 13.2 only. Unless therwise directed by Dyalog, it is most unlikely that this enhancement will be of use.
The latest .NET DLLs can be found at the bottom of this page.
15th February 2013
These fixes apply to 13.2 UNICODE only.
To install the patch, download the 32-bit or 64-bit zip file as appropriate. Unzip into a temporary directory and then copy the .dll and help
directory into the Dyalog installation directory.
Note: Dyalog only supports the Array Editor with the Unicode edition of Dyalog APL 13.2 for Windows. Visit www.davidliebtag.com for support for Classic editions and for other APL dialects.
14th January 2013
These fixes appear in 13.1 only.
The latest .NET DLLs can be found at the bottom of this page.
12th September 2012
This is Conga version 2.3. It adds support for Integrated Windows Authentication (IWA) and a number of minor bug fixes. Conga 2.3 will
be issued with Dyalog APL 13.2, but will work with Versions 13.0 onwards; it is possible to use Conga 2.3 with Dyalog APL Version 12.1 - please
contact support for more information. Conga 2.3 is also available for Linux and AIX - please contact support for more information.
To install, download the appropriate zip file for the version of Dyalog APL which you are using and extract the contents of the zip file into the Dyalog installation directory. Note: because the name of the dlls etc includes the Conga version number you should copy the DRC namespace from the included workspace so that you pick up the correct dlls.
10th September 2012
Note that .NET 4.5 comes as part of Visual Studio 2012.
Note also that the fix for 8668 does not appear in 12.1 since DECF support was added in 13.0 onwards.
The latest .NET DLLs can be found at the bottom of this page.
22nd May 2012
This enhancement allows the user to select whether, when in Classic Edit/Trace mode, the session window can appear ontop of open edit/trace
windows or not. This applies to Version 13.0 onwards.
This option is associated with the SessionOnTop string value in the Dyalog key in the Registry; it is possible therefore to use regedit to
add this value to the Registry. However, if you would rather use the Configure box to do so, you will need to download and install the
appropriate version of dyares*.dll.
To install this fix, download the appropriate dyares*dll file into a temporary directory and then replace the existing dyares*dll in $DYALOG.
We strongly recommend that you take a copy of the existing dyares*dll file beforehand.
These dyares*.dll files should only be used in conjunction with interpreters with an SVN greater than 13.0.13294 or 13.1.13294 as appropriate.
20th March 2012
This issue affects only 64-bit versions of Dyalog APL running under Windows.
Symptoms include APL hanging, or syserror 28s. It has only been reported in environments in which APs were restarted very
frequently, although the issue could arise in any 64-bit APL under Windows.
If you have compiled and linked your own APs, then you will need to relink with the new libraries which are in xfsrc.
To install this fix, download the appropriate zip file, and then extract the contents into the xflib and xfsrc directories under $DYALOG.
24th February 2012
It is not possible to use a Signature that contains an array of exported objects in a function exported to a .NET assembly.
The fix for this requires new .NET interface files, which are on the DSS web pages. This is for 12.1 and 13.0; the version number in both cases is 12170.
The latest .NET DLLs can be found at the bottom of this page.
18th January 2012
Running .NET functions in multiple APL threads could generate a memory leak
The fix for this requires new .NET interface files, which are on the DSS web pages. This is for 12.1 and 13.0; the version number in both cases is 11558.
The latest .NET DLLs can be found at the bottom of this page.
29th November 2011
APL functions used as .NET delegates do not correctly return valuetypes
The fix for this requires new .NET interface files, which are on the DSS web pages. This is for 12.1 and 13.0; the version number in both cases is 11154.
The latest .NET DLLs can be found at the bottom of this page.
25th October 2011
The use of some .NET delegate types could generate an ArgumentException (Duplicate dynamic module name within an assembly.)
The fix for this requires new .NET interface files, which are on the DSS web pages. This is for 12.1 and 13.0; the version number in both cases is 10845.
The latest .NET DLLs can be found at the bottom of this page.
20th July 2011
In certain circumstances when APL functions which are .NET callbacks are on the stack, running )SI can result in a syserror.
The fix for this requires new .NET interface files, which are on the DSS web pages. This is for 12.1 and 13.0; the version number in both cases is 9921.
The latest .NET DLLs can be found at the bottom of this page.
10th July 2011
In V10.1 and prior of Dyalog APL it was possible to put the dyalog DLL in the same directory as an
exported In-process server; this functionality was removed in 11.0. This functionality has been
restored to 12.1 and 13.0, but to be effective does require a new dllstub.dll. There is no need to
download this file if you are not proposing to create In-process servers.
To install, download the appropriate zip file from the list below, unzip the dllstub.dll file from
the zip file, and copy it into $DYALOG (the directory where your interpreter resides). You must re-export
your In-process server for this change to be effective.
22nd May 2011
If you patch 12.1 to 12.1.1.9220 or 13.0 to 13.0.9220 or greater, then you MUST apply these .NET interface patches;
failure to do so will result in all .NET-related APL code failing.
007273: The :Base keyword does not invoke the base constructor on the correct thread.
007274: The :For keyword does not create a .NET enumerator on the correct thread.
The latest .NET DLLs can be found at the bottom of this page.
Note that this is the first .NET update for V13.0; the update process differs from that for 12.1, and will be further
enhanced in future V13.0 .NET interface patches.
11th April 2011
007048: Accessing the .NET framework from a thread who's parent thread has ended could occasionally crash the interpreter

This latest set of .NET interface files has just this one fix over and above what was previously posted.
The latest .NET DLLs can be found at the bottom of this page.
15th November 2010
The latest set of .NET interface files have no additional fixes above what was included in the set posted
on 1st November 2010. This is a packaging fix, to include the .NET bridge file for APs.
If you have already installed the interface files dated 1st November, there is no benefit to installing this set.
The latest .NET DLLs can be found at the bottom of this page.
1st November 2010
This latest set of .NET interface files includes fixes for the following issues:
006424: Odd results when looking at certain .NET string arrays
006452: The UNICODE interpreter does not convert .NET arrays of System.Char of rank >=2 correctly
006446: Returning the incorrect type from a function exported in a .NET assembly could generate a System.ExecutionEngineException
006496: The DyalogProvider class (for ASP.NET) incorrectly uses the word "virtual" instead of the keyword "overridable"
The latest .NET DLLs can be found at the bottom of this page.
8th October 2010 (updated)
006419: It is now possible to cut the stack back when tracing a .NET callback or function called by .NET.
To achieve this APL flags an exception to .NET, expecting that .NET will in turn flag an exception once .NET has
finished its own exception handling.
[update] The fix for this enhancement requires a change to both the .NET dlls, and to the APL interpreter;
you must have the .NET dlls from 8th October or later installed, as well as an interpreter with a version number
of at least 12.1.1.6709.
006420: The value passed to a property setter function had incorrect shape when called from .NET.

Re: 006113: UCS-4/UTF-32 characters are truncated when being passed across the .NET interface
The original fix did not cover all cases of data being passed across the interface; this fix
completes the coverage.
The latest .NET DLLs can be found at the bottom of this page.
25th June 2010
The packages listed here supercede all previous V12.1 .NET DLLs and AP support, and include
all fixes that have been included in previous packages. Once installed it will not be necessary to
install any previous packages detailed on this page.
The .NET DLLs include a number of bug fixes related to exporting .NET assemblies, and includes
a fix for 006113: UCS-4/UTF-32 characters are truncated when being passed across the .NET interface. Note that there is
a further fix for this bug here
The .NET DLLs can be found at the bottom of this page.
The AP zip files includes the entire contents of the xflib and xfsrc directories; these zip files therefore
supercede all previous V12.1 AP fixes.

27th January 2010
Re: 005583: 12.1 Windows 64 bit APLs: apld.lib asserts when trying to run recompiled APs
There was a problem with the AP interface for V12.1 64-bit APLs for Windows which prevented APs compiled by users from running.
The fix for this includes a change to the AP interface in both the interpreter and the APs. It is therefore necessary to
ensure that either both the interpreter and any AP (including those supplied by Dyalog) are dated 2010-01-18 or later, or
that both the interpreter and any AP are both dated 2010-01-11 or earlier. You will need to rebuild all APs after having installed
the new apld.lib and apl.lib which are included in the appropriate zip file.
The following two zip files include recompiled qfsck.exe, strand.exe, xutils.exe, and apld.lib and apl.lib. To install, download the appropriate zip file, and extract the files into $DYALOG/xflib and $DYALOG/xfsrc.
27th October 2009
All 64-bit versions of Dyalog APL from V11.0 onwards have been enhanced so that they support mapped variables. Additionally
the util workspace has been updated so that the functions ∆MPUT and ∆MAPPEND support 64-bit variables.
Note: mapped variables can only be accessed using the same interpreter that created the mapped file. That is, they can only be accessed
with interpreters that have the same width (32- or 64-bit) and the same chip type (little- or big-endian); classic and unicode interpreters
that have the same width and chip type can access each other's mapped files, provided that those files do not contain character arrays.
If it is necessary to convert the contents of mapped files containing APL variables from one type of interpreter to another, then it will be
necessary to use component files, DWSOUT/DWSIN or some similar method.
Dyalog may remove or relax these limitations in future releases.
To use mapped variables in a 64-bit interpreter, you will need to download util.dws (those using *nix-based interpreters may wish to rename the file as "util"). Additionally you will need to use a 64-bit interpreter created or patched on or after 27th July 2009. Interpreters created before this date will return a NONCE ERROR.
8th February 2009
From February 2009, the DSS pages will be hosted at dss.dyalog.com. Eventually,
www.dyalog.dk will no longer host DSS pages and you will need to use new patch workspaces:
20th May 2009
#4616 is a problem for 32 bit auxiliary processors with V12.0 only. There is a memory leak when releasing any array of doubles of
odd rank; Dyalog recommends that you recompile all APs in order to avoid potential problems.
#3895 and #4233 fix issues with ss in the Unicode versions only
It is not therefore strictly necessary to install the 64 bit classic version; the executables and source files etc are included for completeness. These fixes also include those for #3680, mentioned below.
To install:
Download the appropriate zip file, and extract the contents of both the xflib and xfrsc folders into the folders of the same name
in $DYALOG.
28th October 2008
Updated executables, to go in the xflib folder:
Updated C files which should go into the xfsrc subdirectory:
6th June 2008
Three "stub" files shipped with version 12.0.1 contain references to the incorrect DLL names.
If you get an error message referring to DLL's with names containing "111", you need to download
updated stub files and place them BOTH in $DYALOG and in the $DYALOG\bin folder.
Note that the stub files shipped in the 12.0.3 release (which is the one that has been available for download since August 2008) are NOT in error; this
applies only to the stub files shipped with the 12.0.1 release.
Download updated stub dlls (Last updated 04 June 2008):
28th February 2008
This download contains version 5.0.2.17 of SQAPL for Dyalog APL 11.0 32-bit; later versions of the interpreter include this SQAPL version already.

This mechanism replaces the files held in the GAC and in $DYALOG\bin directory. If you
have taken copies of these files, then you will need to replace these copies too.
In some circumstances it may be necessary to delete older versions from the GAC; if you are unable to delete these files
because they are in use, you will first need to delete the appropriate entries for bridge files, dyalognet files and dyalogprovider
files in HKEY_CLASSES_ROOT\Installer\Assemblies\Global.
