# Release Notes

## v4.0.0 - February 14, 2018

eXist-db v4.0.0 has just been released. This is a major release, which contains, API changes, several new features and bug fixes.

### Features Added fn:unparsed-text, fn:unparsed-text-lines and fn:unparsed-text-available functions. Implemented HTML ASCII Case Insensitive Collation for XPath 3.1. Replaced ASCIIFoldingFilter with ICUFoldingFilter in NoDiacriticsAnalyzer for better language search support. New User Manager application shipped for the Dashboard. Updated Cache Extension Module: Now implements an LRU policy with both TTL and size options. New functions: cache:names(), cache:keys($name), and cache:destroy($name). Scheduled task option unschedule-on-exception is now exposed in conf.xml. Each thread that eXist creates is now explicitly named for easier identification. Bash Scripts now use /bin/env to locate bash. Updated third-party dependencies: Apache Commons Configuration 2 2.2 Apache Commons IO 2.6 Caffeine 2.6.1 EasyMock 3.5.1 Eclipse AspectJ 1.9.0.RC2 Eclipse Jetty 9.4.8.v20171121 IBM ICU4j 60.2 Jackson 2.9.3 Java 8 Functional Utilities 1.12 Log4J 2.10.0 XMLUnit 2.5.1 * YAJSW 12.11
## Performance Improvements * Cache Extension Module rewritten to use Caffeine.
### Bug Fixes Corrected concurrent access to Document Metadata, previously incorrect due to lazy-loading and incorrect locking. DocumentSets now always unlock all locks that they acquired. Fixed a number of issues with xs:base64Binary and xs:hexBinary returned from XQuery execution in various API's. Fixed a regression with XQuery Update insert into an empty element. Fixed a bug in the EXPath HTTP Client with connection pooling. Fixed a bad thread synchronization in JMX. Corrected invalid type empty() to empty-sequence(). Fixed overzealous locking in XML:DB Local API copy operations. Fix to Namespace handling on in-memory DOM nodes. Fixed a NullPointerException in fn:id. Fixed comparison issue with empty sequences. Fixed broker leak in Image Extension Module. Math Extension Module functions now correctly report their namespace prefix. Improved function signatures types: map to `map()` array to `array()` function to `function()` Fixed the XQuery Error Codes of several atomic value comparison operators. Improved warning and error messages during EXPath Package deployment. Many file path related fixes for building and running on Microsoft Windows platforms. Removed last Java Endorsed Library paths to support Java 9. Updated the Java AppBundler (which is used for staring eXist), to provide better Java 9 support. Build labels are now correctly calculated when building from an installed (not-git) product. * IntelliJ IDEA project files now support correct ApectJ tools.
### Apps The bundled applications of the Documentation, eXide, and Monex have all been updated to the latest versions. A new UserManager application is also shipped, which replaces the previous in-built UserManager of the Dashboard.
### API Changes Legacy XQuery draft syntax empty() has been removed. You should now use the spec. compliant syntax empty-sequence(). The previously numeric type was renamed to xs:numeric. numeric is now marked as legacy. The legacy Atom module (org.exist.atom) has been removed. Sending an invalid XQuery to the RESTServer now correctly returns HTTP 400 Bad Request, instead of HTTP 202 Accepted. XMLDB API interfaces have been renamed to be more consistent (e.g. EXistXQueryService) Locks are now re-acquired by a Transaction rather than ownership transferred.

### Backwards Compatibility

  • eXist-db v4.0.0 is backwards binary-compatible as far as v3.0, but not with earlier versions. Users who are upgrading should always consult the Upgrading Guide in the documentation.
  • NOTE: The version of Dashboard that was installed with eXist-db 3.6.1 (or earlier) is incompatible with eXist-db 4.0.0. If you plan to migrate your entire database to eXist-db 4.0.0, you MUST take one of the following steps to allow Dashboard to work after the upgrade:
    1. If you have not yet installed eXist-db 4.0.0, open Dashboard > Package Manager, and upgrade Dashboard to 0.4.10, or run this script in eXide or the Java Admin Client: repo:install-and-deploy("http://exist-db.org/apps/dashboard", "http://demo.exist-db.org/exist/apps/public-repo/modules/find.xql"). Then you may safely install eXist-db 4.0.0 and use Dashboard.
    2. If you install eXist-db 4.0.0 before upgrading Dashboard, run this script in eXide or the Java Admin Client: repo:install-and-deploy("http://exist-db.org/apps/dashboard", "http://demo.exist-db.org/exist/apps/public-repo/modules/find.xql"). Then you may use Dashboard.
### Downloading This Version * eXist-db v4.0.0 is available for download from GitHub. * Docker images for are available from EvolvedBinary's DockerHub. * Maven artifacts are available from our mvn-repo. * Mac users of the Homebrew package repository may acquire eXist 4.0.0 directly from there.
