Specifies the version of the tag.

propertyVersion: TJvID3Version;
Description
Use Version to determine the version of the tag or translate the tag to a specific version. Supported versions are:
- ID3 tag version 2.2.0 (ive2_2).
- ID3 tag version 2.3.0 (ive2_3).
- ID3 tag version 2.4.0 (ive2_4).
Version 2.2.0 is obsolete, and tags should not be written as this version.
You can use the ReadVersionAs property to specify to what version the tag will be translated after the tag has been read. Use the WriteVersionAs property to specify as which version the tag will be written.
Some differences between version 2.3.0 and version 2.4.0 are:
- Only version 2.4.0 supports UTF-16BE and UTF-8 encoding for frames (See TJvID3Frame.Encoding).
- Version 2.4.0 tags can include a tag footer. (not implemented by TJvID3Controller).
- Unsynchronisation is done on frame level in version 2.4.0, instead of on tag level.
- Some frames are deprecated as of version 2.4.0, others are introduced in version 2.4.0. Bychanging property Version the tag controller automatically translates deprecated frames to newly introduced frames and vice versa. For example, if you change Version from ive2_4 to ive2_3, the tag controller, will remove fiInvolvedPeople2 and fiMusicianCreditList frames, and combine these into a new fiInvolvedPeople frame.
