Java Web Start
Java Web Start has been deprecated as of Java 9, and has been removed in Java 11, the current long-term release. As of v5.x of netCDF-Java and the TDS, Web Start files and features have been removed. We continue to publish the current set of Java Web Start files (netCDFtools.jnlp and netCDFtoolsExtraJars.jnlp) for v4.6.x at least until the TDS has reached a stable v5.0 release. At some point in 2021 (post TDS 5 release), it is our plan to remove all netCDF-Java and TDS related Web Start files from Unidata servers, and the Web Start functionality provided by TDS v4.6 and prior will no longer work. Users will still be able to download ToolsUI and run the application locally, just not through the Web Start mechanism. In anticipation of this removal, the 4.6.x line of development for the TDS (starting with v4.6.17) will no longer generate viewer links to Unidata hosted Web Start viewers. The Godiva2 client will still be available as a Viewer for gridded datasets in v4.6.x of the TDS, and the ability to add custom viewers to the TDS will continue to work. While TDS v5 does not include Java Web Start based viewers, it does include the updated Godiva3 client, as well as a new Jupyter Notebook viewer service.

v4.6.15
netCDF-Java (maintenance) and the THREDDS Data Server (stable)
Version 4.6.15
This release addresses a critical bug in both the netCDF-Java library and the THREDDS Data Server. See the "Bug Fixes" section below for more details.
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.15 release was announced June 17th, 2019. These are stable releases and contain a variety updates to 3rd party libraries which include security updates, and as such, the development team recommends these upgrades to anyone using the CDM or TDS. Please see the special note below about this and future 4.6.x versions of netCDF-Java.
Notices
This release addresses a critical bug in both the netCDF-Java library and the THREDDS Data Server.
See the "Bug Fixes" section below for more details.
Special note about netCDF-Java
As of this release, the current stable version of netCDF-Java is v5.3.3 (the current stable version of the TDS is v4.6.14). The netCDF-Java code base is now located at https://github.com/Unidata/netcdf-java. This release, v4.6.15, is a maintenance release of the 4.6.x line of development. For netCDF-Java issues, please open an issue on the new repository. Bug fixes will be applied first to v5.x and, if possible, may be applied to v4.6.x. However, the code base has diverged quite a bit, and bug fixes to the 4.6.x line may be impractical. Security fixes, such as upgrading third-party dependencies with known open vulnerabilities, will continue to be applied to the 4.6.x branch in support of the stable version of the TDS. Upon the release of a stable TDS v5.0, such security fixes to the 4.6.x branch will continue to be addressed for at least six months.
Java Web Start
Java Web Start has been deprecated as of Java 9, and has been removed in Java 11, the Long-term Release post Java 8. As of v5 of netCDF-Java and the TDS, Web Start files and features have been removed. We will continue to publish the current set of Java Web Start files (netCDFtools.jnlp and netCDFtoolsExtraJars.jnlp) for v4.6.x at least until the TDS has reached a stable v5.0 release. Java 8 public updates are currently scheduled to end December 2020, at which point Java 11 will be the only LTS release available from the current major providers (OpenJDK and Oracle), although some vendors have committed to patching OpenJDK 8 until sometime later. As of January 2021, it is our plan to remove all netcdf-java and TDS Web Start files from Unidata servers, and Web Start functionality in TDS v4.6 and prior will no longer work. Users will still be able to download ToolsUI and run the application locally. In preparation for this, the next version of the TDS (v4.6.15) will allow server administrators to turn off links to the Web Start viewers found on many Dataset catalog pages. The Godiva2 client will still be available as a Viewer for gridded datasets in v4.6.x of the TDS. While TDS v5 does not include Java Web Start based viewers, it does include the updated Godiva3 client, as well as a new Jupyter Notebook viewer service.

- Backport of Unidata/netcdf-java#320, Unidata/tds#89, in which iteration over multi-file PointFeatureCollection's of type STATION could result in hundreds of locked file handles in the RandomAccessFile cache, all pointing to a single file on disk.
- Fixed critical bug in DiskCache2 which made the generation of unique file names timing sensitive.
The DiskCache2 bug is critical, and due to this, anyone using ucar.nc2.util.DiskCache2 from the netCDF-java library, or the NetcdfSubsetService in the TDS (which uses DiskCache2) should update immediately. THIS BUG MAY LEAD TO DATA CORRUPTION OR FILES WITH INCORRECT DATA AND/OR METADATA. For more information, please see DiskCache2 Issue in netCDF-Java Library.

v4.6.14
netCDF-Java and the THREDDS Data Server
Version 4.6.14
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.14 release was announced July 29th, 2019. These are stable releases and contain a variety updates to 3rd party libraries which include security updates, and as such, the development team recommends these upgrades to anyone using the CDM or TDS. Please see the special note below about this and future 4.6.x versions of netCDF-Java.
The THREDDS Data Server (TDS) is 100% Java, open source, and runs as a Tomcat web server application. TDS data serving capabilities are built on top of Unidata's netCDF-Java / CDM library. The CDM data model combines the NetCDF-3, DAP2, and HDF5 data models into what is called the Common Data Model (CDM). It has a pluggable "I/O Service Provider" architecture that allows it to read various file formats into the CDM, including NetCDF, HDF5, GRIB, NEXRAD levels 2 and 3, and others, as well as datasets served through the OPeNDAP protocol. The TDS then builds data services on top of the CDM.
Notices
Special note about netCDF-Java
As of this release, the current stable version of netCDF-Java is v5.0.0 (the current stable version of the TDS is v4.6.14). The netCDF-Java code base is now located at https://github.com/Unidata/netcdf-java. This release, v4.6.14, is a maintenance release of the 4.6.x line of development. For netCDF-Java issues, please open an issue on the new repository. Bug fixes will be applied first to v5.x and, if possible, may be applied to v4.6.x. However, the code base has diverged quite a bit, and bug fixes to the 4.6.x line may be impractical. Security fixes, such as upgrading third-party dependencies with known open vulnerabilities, will continue to be applied to the 4.6.x branch in support of the stable version of the TDS. Upon the release of a stable TDS v5.0, such security fixes to the 4.6.x branch will continue to be addressed for at least six months.
Java Web Start
Java Web Start has been deprecated as of Java 9, and has been removed in Java 11, the Long-term Release post Java 8. As of v5 of netCDF-Java and the TDS, Web Start files and features have been removed. We will continue to publish the current set of Java Web Start files (netCDFtools.jnlp and netCDFtoolsExtraJars.jnlp) for v4.6.x at least until the TDS has reached a stable v5.0 release. Java 8 public updates are currently scheduled to end December 2020, at which point Java 11 will be the only LTS release available from the current major providers (OpenJDK and Oracle), although some vendors have committed to patching OpenJDK 8 until sometime later. As of January 2021, it is our plan to remove all netcdf-java and TDS Web Start files from Unidata servers, and Web Start functionality in TDS v4.6 and prior will no longer work. Users will still be able to download ToolsUI and run the application locally. In preparation for this, the next version of the TDS (v4.6.15) will allow server administrators to turn off links to the Web Start viewers found on many Dataset catalog pages. The Godiva2 client will still be available as a Viewer for gridded datasets in v4.6.x of the TDS. While TDS v5 does not include Java Web Start based viewers, it does include the updated Godiva3 client, as well as a new Jupyter Notebook viewer service.

v4.6.13
netCDF-Java and the THREDDS Data Server
Version 4.6.13
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.13 were released on February 12th, 2019. These are stable releases and contain a variety updates to 3rd party libraries which include security updates, and as such, the development team recommends these upgrades to anyone using the CDM or TDS.
The THREDDS Data Server (TDS) is 100% Java, open source, and runs as a Tomcat web server application. TDS data serving capabilities are built on top of Unidata's netCDF-Java / CDM library.

Special note about Tomcat
Starting with versions 7.0.73, 8.0.39, and 8.5.7, Tomcat's Standard HTTP Connectors (NIO, NIO2, and APR/native) have started to reject certain characters in query strings when unencoded (HTTP Response Status Code 400). This issue has been discussed on GitHub issue 1144, as well as on the THREDDS mailing list. This impacts the TDS, as square brackets in query strings are rejected (critical for OPeNDAP and cdmremote requests, for example). From the Tomcat docs:
The HTTP/1.1 specification requires that certain characters are %nn encoded when used in URI query strings. Unfortunately, many user agents including all the major browsers are not compliant with this specification and use these characters in unencoded form.
If your server needs to support unencoded characters in requests strings, and you are running Tomcat through one of the standard Connectors, then you can consider using the relaxedQueryChars attribute on the Connector, found in $CATALINA_HOME/conf/server.xml. For more information, see https://tomcat.apache.org/tomcat-8.5-doc/config/http.html#Standard_Implementation.
