• Support the ability to parse objects with extended tags (more than one byte). #65
• Simplify by converting ASN1Length to Dart records

• Make a number of fields final that should not be changed.
• Add types to a few members.
• Remove nullability from a field fields.
• Require Dart 3.0

• Fix null assertion when accessing valueBytes before encodedBytes.

• Reverted parsing of APPLICATION tags to the older behaviour. If the constructed bit is set, the tag is parsed as an ASN1Sequence. The recent updates broke LDAP ASN1 parsing.

• Adds classes to handle non primitive classes: ASN1Application,ASN1ContextSpecific, ASN1Private.
• This is a potential change in behavior for consumers that expect some of these classes to be parsed as primitive or sequence types. See [README.md]
• The encodeApplicationTagsAsObject option on ASN1Parser has been dropped as it is now the default. Consumers should reparse bytes they know to be a sequence, etc.

• Fix #62. Allow context specific tags to be cast to an asn1 sequence.

• Fix #57

• Fix #61. Adds a flag to the parser encodeApplicationTagsAsObject that will force APPLICATION objects to be encoded as ASN1Objects, skipping any attempt to create sequences.

• fix: Use the correct value for unusedBits in ASN1BitString.fromBytes

• Add optional flag whether to relax parsing, off by default, for backwards-compatibility

• Add ASN1BMPString support

• Better toString() for ASN1ObjectIdentifier

• Add ASN1NumericString support

• Bumped to 1.0.0 as this is now null safe
• Code cleanup
