Upgrade and Compatibility Information

Package Compatibility

Package internal files: All generated package internal files are backwards compatible starting from XDCtools 3.20. So, packages created using XDCtools 3.20 or later can be consumed using this release. Because of the addition of the new target type CString, packages created with this release that contain non-metaonly modules can not be used with earlier XDCtools releases. This includes the xdc.runtime package. See XDCtools Internal Version Numbers for additional details.

Package-specific APIs: Each package has a compatibility key defined in its package.xdc specification file. No package compatibility keys were changed in this release.

Please note that the package compatibility keys are independent of XDCtools product release numbers (described in Versioning below). Package compatibility keys:

  1. Enable tooling to identify incompatibilities between components, and
  2. Convey end-user requirements when re-integrating specific components.

Package compatibility keys are composed of 4 comma-delimited numbers - M, S, R, P - where:

Versioning

All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, release candidates, etc.). Pre-releases are denoted with a suffix (e.g. 3.15.01.51-eng) and should not be used in a production environment.

This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.

To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. xdctools_3_15_00_50.

Subsequent releases of patch upgrades will be identified by the patch number, ex. XDCtools 3.15.01.67 with directory xdctools_3_15_01_67. Typically, these patches only include critical bug fixes.

Please note that version numbers and compatibility keys are NOT the same. For an explanation of compatibility keys, please refer to the 'Upgrade and Compatibility Information' section.
