- <p>This document describes the changes made to the asn1 system
- from version to version. The intention of this document is to
- list all incompatibilities as well as all enhancements and
- bug-fixes for every release of the asn1 application. Each release of asn1
- thus constitutes one section in this document. The title of each
- section is the version number of asn1.</p>

- <p>When compiling an asn1 source that reference a type in

- other source to resolve the reference. It also tests
- whether the other source has been updated since the
- asn1db file was generated. This last test was to brutal
- in that it exits compilation when no source was found,
- even though a asn1db file existed. Changed behavior from
- a brutal exit to a warning.</p>

- <p>When a component in a SEQUENCE is a CHOICE (or reference to a CHOICE)
- and the SEQUENCE's component and one of the alternatives in the CHOICE
- have identical names, an error may occur if one doesn't use the
- 'optimized' versions of the compiler. In the older versions (<c>ber, ber_bin, per, per_bin</c>) one could optionally apply a value of a
- component as <c>{ComponentName,Value}</c>, and the generated code
- chooses the second element of the tuple. However, a value of a CHOICE
- must be applied as a tuple: <c>{AlternativeName,Value}</c>. Thus,
- in the rare case described above and if the value to the SEQUENCE's
- component is not in a tuple notation the
- <c>{AlternativeName,Value}</c> will be peeled off in the SEQUENCE
- and the value fed to the CHOICE will only be the <c>Value</c>
- part of <c>{AlternativeName,Value}</c>, and the encoder crashes.
- The best way to avoid this is to use the optimized version of the
- compiler where the unnecessary tuple notation
- <c>{ComponentName,Value}</c> no longer is allowed. Since it isn't
- possible to solve this bug in the compiler.</p>

- <p>The ber_bin option is not officially supported in this version (will be
- in a later version) but is provided for those who want to try it.

- Exactly how performance differs between this binary approach and the
