As we've passed the start of another quarter, several tests have been moved to the New category, meaning that they now are required for conformity assessment. These are: C455001, and B455002. Many tests have also moved from the Allowed Modification to Modified category.
New tests inserted between January 1, 2000 and April 1, 2000 will become required for conformity assessments on October 1, 2000. New tests inserted between October 1, 1999 and January 1, 2000 will become required for conformity assessments on July 1, 2000. New tests inserted between July 1, 1999 and October 1, 1999 will become required for conformity assessments on April 1, 2000. New tests added to the ACATS before July 1, 1999 are now required for conformity assessments. The effective dates of tests are marked in the lists.

Test numbers given are for the basic test. Categories are "Withdrawn" (the
test should not be processed for Ada conformity assessments); "Allowed
Modification" (either the original test or the modified one should be processed for
Ada conformity assessments); "Modified" (the modified test must be processed for
Ada conformity assessments); "New" (the test does not need to be processed for
Ada conformity assessments, but will be added to future baseline ACATS).
ACATS version labels are provided with all new and modified tests. Use this label to
retrieve the test from the ACATS VCS. See "How to get new and modified tests".
In citations, line numbers are given relative to the start of a test file in the format
of '@<line#,line#,...>'; if a test program comprises more than one file, then the
particular file will be indicated by "fn", where "n" is the
test-program name's file-designator numeral. E.g., "B38103E : @f1-31, ... "
denotes test file b38103e1.ada. In cases where there are two or more rationales for
different errors in a test program, these different rationales with their respective line
citations are listed on separate lines. References to the Ada 83 & Ada 95 standards
are given in the format:
These references are to the Ada 95 standard unless "Ada83" is specified.

The official home of the ACATS test suite is the ACAA web site. The site can be accessed from the
Compilers and Conformance section of the Ada IC web site (www.adaic.org). It also can be accessed directly at www.ada-auth.org/~acats - but note that this URL may change in the future.
The complete set of official new and modified tests is available in the Mod_2_2F Zip and Tar files on the ACAA web site.
Individual new and modified tests can be retrieved from the ACATS VCS. Simply navigate to the appropriate directory (folder), and select the test you want. Select the revision you want (usually the most recent) and it will be retrieved for you. Tests are stored in directories that correspond to the test's prefix. For instance, the test CD92001.A will be found in the CD directory. You can also browse the differences between versions of a test.
If you cannot get the files from the official site or you cannot get the files in a format appropriate for your processor, please contact your ACAL (AVF).
The baseline ACATS 2.2 is available in various formats on the ACAA web site.
