The Synopsis documents are the design documents used to guide Perl 6 language, compiler, and test development. As design documents, they're frequently subjected to the rigors of cross-examination through implementation and use in practice. In other words, they may change slightly or radically, but the expectation is that they are ``very close`` to the final shape of Perl 6.
In the past the Synopses have often been referred to as "the formal Perl 6 specification" and "specs", but this usage is being deprecated in favor of treating tests from the "roast" test suite as official specifications. This is consistent with Synopsis 1, which says "Perl 6 is anything that passes the official test suite." [Read more...]
Note that documents marked DRAFT are really just that. They are often written by random people, and may be speculative as much or more than "official specification".
The documents here mostly correspond with the chapters in the Camel Book, that is, "Programming Perl, 3rd Edition". However, a few chapters of that book will no longer be relevant, and those numbers will be resused for other things. At the moment, this refers to section 7, whose synopsis is "Iterators", but whose Exegesis is about the module Form.pm. Apocalypses and Exegeses were only written for some of the early sections; the later sections have no corresponding apocalypse/exegesis.
Most changes to these specifications have been discussed on the
perl6-language mailing list or the
#perl6 FreeNode channel on IRC.
Additionally, Larry Wall has created an implementation of the parser
for Perl 6 (but it doesn't do any of the backend stuff), and that is usually
regarded as authoritative.
While the Apocalypses and Exegeses are linked here for reference, note that they are historical documents, whereas the Synopses are kept more up-to-date and are the primary recommended reference.

The few draft PODs here should probably be cleaned up into Spec-like formats and moved to Perl6::Spec space.
The Differences document is stored in
in the mu repository,
if you'd like to make updates to it. Your changes will
automatically appear on feather in less than 1 hour.

The HTML version of Synopses contains code snippets from the official
test suite. In other words, the .t files from the test suite are
divided into pieces and inserted after corresponding paragraph of
the Synopses. The job is done by the Perl 5 script util/smartlinks.pl
living in the mu repository. It runs once every hour, and is triggered by the file
docs/feather/script/update-syn in the mu repository. It runs as user
pugscode on feather1.
