+
+# Deprecation/Compatibility
+
+
+* {% jira 2287 %} JApi throws checked exceptions without declaring
+
+ Previously Daffodil did not declare some checked exceptions that could have
+ been thrown by some Daffodil API functions. Those are now declared, which
+ requires users of the API to explicitly catch these exceptions or mark them
as
+ thrown.
+
+* {% jira 2287 %} JApi throws checked exceptions without declaring
+
+ dfdl:outputValueCalc is now allowed on global/root elements
+
+* {% jira 2939 %} Remove UpMoveArray
+
+ DFDL expressions with an upward path step (`..`) to an array is deprecated
and
+ now results in a schema definition warning. Future versions of Daffodil may
+ remove support for this and result in a schema definition error.
+
+* {% jira 2324 %} Unparser choice branch selection not conformant to DFDL
standard
+
+ Per DFDL errata 5.60, the first branch that can be unparsed entirely without
+ any infoset events (i.e. made up of elements that are dfdl:outputValueCalc,
+ option branches, zero length arrays, or defaultable elements) in a choice is
+ selected, rather than prioritizing the first empty branch. Also, required
+ arrays are no longer treated as optional and hidden IVCs are only permissible
+ in choices.
+
+* {% jira 2855 %} Scoping different when using dfdlx:repType vs type
+
+ When resolving default properties, Daffodil now gives precedence to innermost
+ referenced schema components rather than the outermost, as described by
section
+ 8.1.4 of the DFDL specification. If this new logic results in a different
+ property value than previous versions of Daffodil then a schema definition
+ warning is issued.
+
+* {% jira 2957 %} dfdl:decimalSigned="no" bugs with negative values and data
representations
+
+ Daffodil now errors when dfdl:decimalSigned=no or dfdl:decimalSigned is
+ not applicable (as in the case of BCD numbers, which are always positive),
but
+ an attempt is made to parse to/unparse a negative number
+
+* {% jira 2768 %} SAX unparse can lead to a hanging thread if the XMLReader
stops sending events
+
+ The DaffodilUnhandledSAXException, which can be thrown when unparsing using
the
+ SAX API and usually indicates a Daffodil bug, is changed from a SAXException
to
+ a RuntimeException. It is no longer a checked exception and does not need to
be
+ caught. It should usually be handled just like any other unchecked
+ RuntimeException.
+
+ When unparsing using the SAX API, `DaffodilUnparseContentHandler.finish()`
+ should be called after `xmlReader.parse(...)` returns, regardless of success,
+ to ensure all resources are cleaned up. For example:
+
+ ```java
+ DaffodilUnparseContentHandler contentHandler =
dp.newContentHandlerInstance(...);
+ xmlReader.setContentHandler(contentHandler);
+ try {
+ xmlReader.parse(...);
+ } catch (...) {
+ ...
+ } finally {
+ contentHandler.finish();
+ }
+ ```

+ Update to Daffodil 4.1.0, support for cross building
+
+source-dist:
+ - "apache-daffodil-sbt-1.6.0-src.zip"
+---
+
+This is a minor release of the Apache Daffodil SBT Plugin.
+
+See the [GitHub page](https://github.com/apache/daffodil-sbt) for details to
enable and configure.
+
+# New Features
+
+* Add support for Daffodil 4.1.0
+* The default value of the `daffodilVersion` setting is changed to `4.1.0`
+* Add support for creating cross daffodil version projects
+* Add new `daffodilPlugin` and `daffodilBin` ModuleID enrichments, used for
+ specifying dependencies to a Daffodil plugin or a saved parser
+* Simplify setting scalaVersion, it now always uses the latest available Scala
+ version compatible with the Daffodil version
+
+# Bug Fixes
+
+* Ensure plugins are built with the same JVM compatibility required by the
+ Daffodil version
+
+# Deprecation/Compatibility
+
+* We now recommend the use of the more modern SBT project definition
+ syntax and the `.daffodilProject()` function. This adds a number of
+ enhancements that follow best practices, and includes improved support
+ for building/testing/etc. with multiple Daffodil versions. When using
+ this function, existing settings can be used except for
+ `daffodilProjectVersionInfos`, which is ignored if specified.
+
+* Plugins artifacts no longer contain the Scala cross version. They are now
+ built with a classifier specific to the version of daffodil they are built
+ with (e.g. `-daffodilXYZ`) similar to saved parsers.
