Changes between release 4.2.1 and 4.2.2 are listed in green.

Changes between release 4.2.2 and 4.2.3 are listed in teal.

We will officially stop supporting JDK 8 when it reached end of Full Support on November 30, 2026.
We will not immediately remove support via our preprocessing step that swaps code based on the JDK compiler, but we will no longer test with JDK 8.
In 2027, we plan to remove support for any JDK less than 17.

Java 17 Migration

OpenJDK End of Full Support is November 30, 2026. We anticipate our next release in this series to have JDK 17 code be the default, but have our preprocessing step that swaps code based on the JDK compiler continue to make the release JDK 8 compatible. We will stop testing with JDK 8 when Full Support expires. In 2027, we plan to remove support for any JDK version less than 17 unless we hear that support is still needed.

What Might Break (Changes in Behavior)

BaseFile/DataFile	-	DataFile constructors have been fixed so that when KeepCase is passed in as a flag, the constructor honors it. The bigger change in progress is that a bug in Java usage, where a quoted all upper case filename is automatically lower cased is being addressed by distiguishing between Java (including OS command usage) and traditional Midas usage (from a macro or nM> prompt). Due to limits in how NeXtMidas RESULTS are handled and the macro language, the legacy/correct behavior for traditional Midas usage is for all upper case file names that make it to this BaseFile (and its child classes) to be assumed to be all lower case. The new default for Java API usage (and OS usage) will be for file name casing to be honored.
CHECKAUTHORIZATION	-	PLEASE INFORM the NeXtMidas team if you are using this command. Usage to perform the actual queries is now limited due to REST attribute services going to a more complex query mechanism. Use this with caution! This command, especially the REST query based portion, may be deprecated in the near future, unless we hear it is still useful.
DATABASE (NMDB)	-	Upgrading to an hsqldb jar that does not have a vulnerability now has the result sets coming back first row first (rather than last). It also causes a divide by zero exception on queries such as: select distinct round(id/0.1,2) as ...., where select distinct round(id/1e-1,2) as ... still works. The code has been adjusted to support getCSV() returning values in legacy order. A static setter can be used to get the new natural behavior. IMPORTANT: Since the hsqldb jar is only used for automated testing, we are only including the JDK11+ version of the jar. We anticipate removing the jar all together when we start the 43x series, as having it bloats the baseline and increases the risk of releases having a CVE.
DATALIST/DataFile	-	listElements(double,int,String,int) has been updated to use different API which allows a scalar separator to be specified for listing type 1000 and default elements. The default scalar separator was ',', but as of NeXtMidas 4.1.2, it is '\|'. To change this delineator, use the static setter DataFile.setScalarSeparator(String).
LayerWMS	-	wms_coor_sys.xml has been updated to prefer the newer EPSG:4326 Coordinate Reference System over the older CRS:84.
MApplet	-	Applet support is being dropped from the 41x series, since Java has marked Applets as deprecated for removal. Though the direct dependencies have been removed in 4.1.0, extra code clean up will be done in future releases.
PLOT/ALL	-	PLOT/ALL of a 1000 file will automatically prescale the data, as the purpose of the /ALL switch was that all the data would be rendered within the plot bounds. Without this fix, some of the 1000 data can end up beyond plot bounds, without the user realizing it. The only reason this is listed in the What Might Break is that prescaling does add a small amount of overhead.
SSSLCONFIGURE/SSLUtilities	-	PEM file requirements: 1) .pem follows good security practices and only has one certificate chain 2) .pem has each of its certificate chains start with the private key (ex: private key, primary cert, intermediate certs, root cert) If multiple private keys are found and the preferred order (private key first) is not followed, the load of the .pem is aborted, as there is not a reliable means of handling key and certs being in any order. Even if the preferred order is followed, the user will be warned about multiple private keys.
SSLUtilities.verifyGroupProject and SSLUtilities.verifyUserAttribute	-	These methods were intended for use by CHECKAUTHORIZATION, rather than direct usage. As mentioned with the CHECKAUTHORIZATION command, these are beyond useful life as REST attribute services are going to a more complex query mechanism. Please let the NeXtMidas team know if you have an application where they are useful, as the plan is to deprecate these methods.
Time	-	Times greater than one day and less than or equal to one year have been displayed in 1950 time formats. As of 4.1.2, times greater than one day and less than or equal to one year are displayed in relative time formats, such as 'DDD:HH:mm:ss.SSS' for STD and ACQ times, as well as 'sec_in_year' for EPOCH times.

New Features Added

Intel oneAPI 2021	-	As of 4.0.1, XBC and NeXtOpt have been tested with Intel oneAPI 2021. Intel oneAPI provides a free version of Intel that does not require a license to use it.
RHEL 8+	-	As of 4.2.0, NM_FORTRAN accepts 'gfc', 'gfc-gfortran', or 'gfortran' for the gfc FORTRAN compiler.
	-	NeXtMidas will autodetect which compiler to use based on the OS.
	-	The JDK 8 tools library is not and will not be FIPS compliant. NeXtMidas supports multiple options for working with JDK 8. In all cases our TLS is 1.2 and is FIPS compliant and the overall Linux setting remains FIPS compliant. One option is to compile NeXtMidas code with JDK 8 and to use a separate JDK 17+ for JAR signing and other actions that require using Java tools library. The default is to turn off FIPS for JAR signing and other direct Java tools usage. See the SecureRHEL8FIPS.html page in our User's Guide for more details.
	-	Earlier versions of NeXtMidas require softlinks to use the gfortran. In support of this, the script gfc-softlinks-rhel8plus.sh has been added to the 414 and 405 release packages.
LIBNXM / Reduced Footprint Build Options	-	A number of reduced footprint build options are available as of 4.1.3. See our User's Guide for more information (links below work when docs are built). NXM With Fewer 3rd-Party Dependencies NXM Without Large DAT Files Library NeXtMidas (LIBNXM)
JDK Compiler based code	-	Due to the need to continue to support JDK 8, while also supporting the most current JDK, we are beginning to support very limited pre-compile code swapping based on a .jdk, .jdk## convention. This is done automatically and keeps users from needing to manually uncomment or comment out code to get efficient or fully functional behavior. As of NeXtMidas 4.1.1, the only code affected is the CallStackUtil code and MulticastSocketOptions code. To get full and efficient JDK9+ behavior required following directions in CallStackUtil.java and uncommenting and commenting out code. Even so, this still left users with a log message with a stacktrace. Advanced details: The minimal code that needs to be swapped is now in CallStackUtilSwap.jdk08 and CallStackUtilSwap.jdk (and MulticastSocketOptions respectively). The .jdk08 indicates that version will be placed in CallStackUtilSwap.java (or MulticastSocketOptionsSwap.java) when compiled with java versions up to 8. The .jdk indicates that version will be copied to the java file for all JDK versions beyond the latest ## (in .jdk##). This should largely be transparent to the user, both with traditional NextMidas builds and with Gradle builds.
New Commands	-	CHECKTIMEKEYWORDS;SYS - Visualization tool for diagnosing issues with uSec or TC high precision time codes
	-	CONVERTARGB;SYS - Converts type 2000 data to ARGB (Alpha\|Red\|Green\|Blue) direct color format. A new /ALPHA0COLOR switch has been added which will force one color (generally the background - no signal present color) to be transparent. This allows multiple rasters to be displayed on single plot.
	-	POLYMAP;SYS - Supports creation and customization of Type 1999 files. These 1999 can be created from either ShapeFiles or GeoJSON files. Customization options include skipping or keeping specified polygons or replacing coordinates in specific geographic regions.
	-	SHAPEMAP;SYS - Supports creation of customized ShapeFiles. Individual polygons can be reshaped by replacing coordinates in a certain geographical areas with other coordinates.
	-	WEBVNCSERVER;WEBVNC - An HTTP/1.1 server that proxys a VNC session to a HTML Canvas using noVNC. Automatically starts a vncserver and websocket proxy for each client. Since NeXtMidas 4.1.1.
New Option Tree	-	minio - New MinIO Support for S3 Bucket Access Compile time dependency: minio jar (included) Run time dependencies: see minio_dependencies.txt S3 commands: S3GET, S3LS, S3PUT, S3RENAME, S3RM NXM command support (NOOP, FFT and STATUS)
Macro/Shell Enhancements	-	Startup Macros can now accept arguments *Example:* $ java -DNMSTARTUP.USER="nxm.sys.test.args_startup.mm HELLO THERE" -jar $NMROOT/jars/nxm-sys.jar
	-	Improved Macro ERROR checking and messages.
Libraries	-	DataFile - Better support for PLATINUM files. When PLATINUM files are used as input to a function (ex: FFT, not just STATUS/KEY) the default is now to use the NeXtMidas underlying libraries for PLAT2BLUE conversion to automatically convert PLATINUM Keywords to BLUE. A warning is issued when the PLATINUM file is missing keywords (as defined by the JICD 4.2 ICD). This default autoconversion of PLATINUM can be disabled globally or on a file by file bases. The previous behavior was to error out under these conditions.
	-	DataTypes New 'J' 12-bit packed Data Type was contributed by Jeff Schoen for 4.1.2 >12-bit is primarily designed for data transfer and storage DataFile.write requires writes to be at even byte boundaries (ex: transfer lengths that are multiples of 2 for SJ data) Most commands, including PLOT, FFT, and WAVEFORM, are supported, but some require extra care when working with SJ. (ex: DATALIST number of columns should be a multiple of 2) When an 'I' value is placed in a 'J', the top 12 bits are saved
Gradle Support	-	Support has been added to convert NeXtMidas to a gradle directory structure (full restructure or softlinks options) and to publish artifacts to Nexus. Please find instructions located at $NMROOT/gradle/README.txt
	-	Support has also been added to convert user option trees to a gradle directory structure (full restructure or softlinks options). Please find instructions located at $NMROOT/gradle/README.txt
	-	Support for pulling some dependencies and relying on local jar files for others, as well as pulling only the dependencies needed when opting for LIBNXM mode or another reduced footprint option.
Midas versus Java usage detection	-	Support for detecting Midas versus Java usage is being phased in. The immediate need was for the casing for file names passed in in quotes via Java API to be honored, rather than having all upper case names automatically converted to all lower case names. There are other scenarios users have been experiencing where traditional Midas behavior conflicts with Java behavior. With many users running primarily as a Java Application, it is important for Java usage to be compatible with other Java code. For the 41x/42x series legacy behavior will continue to be the default. Starting with the 43x series auto-detection of Java versus Midas usage will be the default. NeXtMidas usage coming from a macro, nM>, or single-shot mode (nm ....) will be auto-detected as traditional Midas usage, where running a Java application from a main will be considered Java usage. As of 4.1.4 users can opt in to Java usage via the environmental variable NM_JAVA_MODE being set to "ON" or by setting needJavaBehavior() on their Midas instance.
Existing Commands	-	The list below contains NeXtMidas commands. Each command is listed with the new feature that has been added at the request of the user.
	-	CONVERT BLUE2JSON - Basic BLUE2JSON (similiar to BLUE2XML) support was added in NeXtMidas 4.1.1. Additionally, BLUE2JSON can have an OPTIONS={keyword_conversion_table} specified that allows mapping of the keywords to a nested JSON output. A limited number of conversion options (other than direct mappings) are also available. The options are similiar to those supported by KWCONV. Both of these are in a functional Beta stage. See the CONVERT explain file and FileUtil.java for more details. XML2TAB now has some support for handling dots in keys. The Table created is a provisional Table, with the +AllowDotsInKeys flag set. A warning is issued when the XML contained '.'s in keys and this type of Table is created. It is strongly recommended that the '.'s in the Table keys be replaced before serialization, otherwise the current default substitute in this case is ''. The nested key get via the key1.key2.key3 syntax does not work on these +AllowDotsInKeys Tables, but they are restricted to the access methods used by Java Maps.
	-	GCONTROL New TVAL .... /fmt="HH:MM:SS.SSSS" The HMS format now supports fractional seconds, where the number of fractional seconds is specified by the number of 'S' characters beyond the decimal place. See gcontrol.exp
	-	IF AEXISTS - Any type (file or directory) exists
	-	FEATURE *New* Both plot/MPlot Features and LayerDrawable Features can be placed in groups. The Features menu now uses a tree type display, placing Features under their Feature Group name.
	-	FFT *New* The /CMAG switch can be used to apply /MAG, /PSD, and /LOG to cross spectrum output.
	-	MACRO *New* Macro error reporting is greatly improved: lists all conditional block closing errors, gives line number and command, handles includes better.
	-	PANEL *Auto Grid* - Support of uneven layouts
	-	PLOT New IQ plot readouts now include radius (4.2.1) *LayerGeo* - Horizon at Altitude support New LayerWMS GWC=true This WMS option enables GeoWebCache friendly settings, to allow cached results to be returned. (4.1.0) New WMS layer transitions can now be customized, allowing base layers to be automatically set based on the visible area of the map (zoom level). (4.1.0) New LayerWMS ByNameCRSs= is a shorter means of giving preference to a Coordinate Reference System (4.1.0) New LayerWMS RequestVersion This WMS option must be set before the URL is specified. LayerWMS defaults to preferring the latest WMS version supported (i.e. 1.3.0). This option allows an easy override to force a preference for version 1.1.1. (4.0.0) New Layer2D /CUTS switch allows a cross-section "cut" on piped data. (4.1.2) New LayerT5 ellipsoids can now be plotted as a wire cage. (4.1.3) New LayerT5 highlight and visibility filter support based on a Java Map containing key (field name) / value (Java Predicate) map. (4.1.3) New READOUTS include radius on IQ plots(4.1.4) New Time axis READOUTS will default to DateString, rather than Scientific E9 times. This is intended to make the readout human readable. To get old behavior add -DateString to remove this READOUT option (4.1.4) New LayerGeoJSON This new Layer adds support for plotting GeoJSON files with file extension .geojson (4.1.4) New PLOT/ALL of 1000 files now have automatic prescaling of data. Those with 256000 or less will consider all the data in the prescale, and thus ensure all data points are visible. Those with more elements will have a random sampling of there elements to help ensure that the data points show within plot bounds. (4.1.4) *LayerShape* - Country/Shape Name Labels - See PLOT EXPLAIN file. New Point3D.getLinePointsInAOI API allows LayerT5/Point3D line segments to be selected via a dragbox. This does not require the actual points being included in the dragbox area, but just that the line connecting them cross the AOI.
	-	QUERY *Capability Restored To:* Display full signatures and show inherited and interface methods in separate section.
	-	RMIF /STATEM enables state machine based message handling for NXM to NXM or NXM to M2K communication. rmif.for was not updated, so this switch should not be used for NXM to XM communication.
	-	STATISTICS Support for REALMIN, REALMAX, IMAGMIN, and IMAGMAX with complex input.

Known Third-Party Bugs and Limitations

The following are known third-party bugs and limitations that may cause problems for NeXtMidas users.

RHEL 10 Monospaced text height change	-	The underlying Font used for Monospaced now has a text height of 17, rather than the previous 15. NeXtMidas defaults to Monospaced for text. This especially affects panel graphics and the laying out of the graphical controls in Pane0.
JDK 17.0.1 libsvml.so name conflict (JDK-8276025)	-	JDK 17.0.2 has fixed a 17.0.1 issue caused by Java adding a library with a name conflict with a common native library. 17.0.1 causes the XBC option tree build to fail with an UnsatisfiedLinkError.
OpenJDK 8 versions earlier than 1.8.0_312 are not supported	-	To avoid deprecation warnings about too weak of a signing certificate, the NeXtMidas self-sign certificates were updated to a standard that is not supported in earlier JDK 8 versions
Reflective Access JDK 9+ (warning) JDK17+ (error)	-	Warnings are thrown for illegal access using reflection in Java 9 and up and errors in JDK17 and up. When running from When the running via the NeXtMidas start script, the jvm options shown below are included and there are no warnings or errors. To bypass the warning/error, add this to the jvm runtime options: --add-opens java.logging/java.util.logging=ALL-UNNAMED --add-opens java.base/java.security=ALL-UNNAMED For more information please visit Oracle JDK 14 Documentation
RHEL 8 GCC 8.5.0	-	We have put in a workaround in rmif.for for a bug in the GCC FORTRAN compiler that comes with RHEL 8. This allows our NeXtOpt code to build and run, but please let us know if you experience any further issues building and running with this compiler. Fritz Reese has narrowed down this bug and states: The compiler crash (ICE) is triggered by STRUCTURE /PACKETSTRUCT/ having 8 fields followed by a UNION. When –fdec is combined with –finit-derived and –finit-local-zero, some code in the compiler creates a bad initializer for instances of PACKETSTRUCT which leads to invalid memory access. It turns out this happens because the routine that adds an element to the field initializer vector for unions uses an insidious macro which apparently modifies the vector pointer on resize; the default size of this vector is 8 elements, so upon adding the 9th field initializer the vector is resized by allocating a new vector, copying the elements over, freeing the old vector, and reassigning the pointer variable. Since the union routine took the vector pointer as an argument (by value), the caller’s vector pointer wasn’t updated after the resize, and therefore the caller’s idea of the vector was a pointer to freed memory. Chaos ensues later at random points in the compiler which deal with this initializer vector during optimization, finalization, etc... Unfortunately, because of the nature of this bug, subtle changes in how the compiler visits the initializer trees and how other memory is allocated can mask the bug, so there’s no guaranteed workaround other than to ensure there’s no union which is after the 2*8^n-th field (9th, 17th, etc…) in a structure.
VNC	-	It has been noted by users that NeXtMidas will not function in a VNC session if the -depth option is set to 32. 32 is an invalid color depth, valid -depth option settings are 8, 16, and 24. We recommend the default -depth setting of 16.

Known Issues

StateVector	-	The CubicHermite (the default in NeXtMidas 3.2) and QuinticHermite (optional in NeXtMidas 3.3) interpolation options do not appear to be working properly, particularly at the first and second derivative. At this time it has not been confirmed if the issue is due to a bug in the interpolator or just the results from using bad test data (i.e. sv1.prm which came from X-Midas). This affects both the StateVector library and the SVINTERP function in CONVERT which uses it. The suggested work-around is to use the Linear interpolation option until this issue is resolved.
CALL	-	A SUBROUTINE does not have limited scope, scope is the same as procedure.
CONVERT	-	Tables created by the XML2TBL function may appear to "drop entries" when dereferenced. Since XML2TBL is deprecated, this will not be fixed, use the XML2TAB in place of XML2TBL.
GCONTROL	-	Some controls do not support headless mode.
LIST2	-	The table for a /LEGACY select message may contain "extra" fields.
	-	Row/cell selection is undefined when listing a pipe.
	-	Type 2000 files with very large frame size may not load properly.
NeXtOpt	-	NeXtMidas commands run from inside an X-Midas macro (specifically when using PIPE or XPIPE) may exit prematurely. For example a NeXtMidas intrinsic run from the INITIALENTRY of a controls section can cause the pipe to stop prematurely.
	-	May get warnings about problems mapping to the messages section if the X-Midas message queue is not up.
XBC	-	XBC does not support running two copies of the same command simultaneously.
	-	Do NOT use "-check all" with the Intel compliers because some of the legacy fortran libraries make assumptions that are incompatible with "-check all" causing unnecessary aborts (SEGFAULT).

Bugs Fixed

All NeXtMidas issues and enhancements are tracked using a bug tracker/database. GForge DR number is included for all customer-submitted bugs. GForge entries are listed "n/a" for bugs that are duplicates or internal use.

Deprecated Functionality

The following functionality has been deprecated and will be removed from future versions:

Command	Deprecated Item	Replacement	Deprecated Since
PLOT	ZOOM and DRAGBOX messages accessed with msg.data(0), msg.data(1), etc.	Use msg.data.xmin, msg.data.xmax, etc.	2.3.0
STATISTICS	IMEAN=	MEAN= (contains real and imaginary values, see explain file)	2.3.0
CONVERT	The XML2TBL and TBL2XML functions.	Use XML2TAB and TAB2XML.	2.5.0
UPDATE	Command dictionary entries without '*' denoting minimum allowable abbreviation.	Include a '*' at the end of the command name in the dictionary if no abbreviation is allowed, otherwise note abbreviation as desired.	2.5.0
TextFile	Automatic enabling of NOABORT flag.	Use NOABORT or FORCEABORT flags as required.	2.5.0
TextFile	Automatic conversion of INOUT flag to OUTPUT when file not found.	Use INOUT or OUTPUT flags as required.	2.5.0
Results	Use of A: with results.	Use S:, behavior of A: will change in future releases.	2.5.2
DataFile	Use of CREATOR= main header keyword.	Use IO= and VER= keywords.	2.5.3
public fields in baseline classes	All public fields in classes in option trees (SYS, DSP, UCL, etc.) included in the baseline (e.g. nxm.sys.lib.BaseFile, nxm.sys.lib.DataFile, nxm.sys.lib.Shell, etc.) have always been meant for read-only and/or internal use only. Some fields may transition to protected or private in favor of the get/set methods as early as 3.9.0.	Use appropriate public get/set methods.	3.5.1
PLOT	All public fields in nxm.sys.prim.plot, nxm.sys.libg.MPlot, nxm.sys.libg.Layer* (e.g. Layer1D, Layer2D, etc.) have always been meant for internal use only. Most will transition to protected access but will still be for internal use only.	Use appropriate public get/set methods.	3.5.1
As of release 2.2.0 LIST is considered to be an "End of Life" primitive. The LIST primitive is scheduled for replacement by LIST2 in future releases.
See $NMROOT/htdocs/api/sys/deprecated-list.html for a list of deprecated library methods.

Deprecated functionality will continue to function for one year or two stable releases after first being marked as deprecated, but its use may result in a deprecation warning (either at compile time or run time). After one year, any deprecated functionality is subject to removal.
