# Changes in 1.5

## Changes that Could Break Older Environments:

- The coordinates inside the Ivy file have been changed to match those of the POM.
- The Apache Compress Antlib now requires Apache Commons Compress 1.14 or later for 7z, DEFLATE, LZ4 and write support for LZMA and Snappy. XZ for Java 1.6 or later is required for write support for LZMA. Brotli dec 0.1.2 or later is required for Brotli support. As a side effect the Compress Antlib now requires Java 7 at runtime as this is required by Commons Compress 1.14.
