# MAS specification changelog
|
|
|
|
## v0.2 (draft)
|
|
|
|
New features, opt-in per statute with `"mas_version": "0.2"`
|
|
(mail-address-semantics MAS-WP-0005; proposals SCP-6 and SCP-7 in
|
|
`docs/spec-change-proposals.md`).
|
|
|
|
- **Stand-ins (SCP-6), §6.3.** `--` for `=` and `---` for `!`, fixed by
|
|
the spec and switched on by `alternate_syntax.resource` and
|
|
`alternate_syntax.interaction`. Matching order: interaction first,
|
|
then resource. No stand-in for `+`.
|
|
- **Destination transforms (SCP-6), §12.1 and §12.2.** There is a closed
|
|
set of five generator transforms. The canonical form is preferred, and
|
|
the generator refuses when the statute does not permit a needed
|
|
transform. An informative section covers integrations, with IONOS and
|
|
Google Groups as examples.
|
|
- **Resource-identifier case (SCP-7), §8.**
|
|
`equivalence.resource_id_case: exact | insensitive`.
|
|
- **Length, §13.** The length is re-checked after transforms.
|
|
|
|
- **SCP-1, quoted equivalence.** A quoted local-part whose content is a
|
|
valid canonical MAS local-part (no quoted-pairs) is equivalent to the
|
|
unquoted form. Receivers treat them identically; generators emit the
|
|
unquoted form; canonical parsers still reject the quoted form (§4).
|
|
Fixture p1-040 note updated.
|
|
|
|
## v0.1.1 (errata)
|
|
|
|
Errata from the reference experiment and the live provider test
|
|
(mail-address-semantics MAS-WP-0002/0003). Proposals and evidence:
|
|
`docs/spec-change-proposals.md` in the implementation repository.
|
|
|
|
- **SCP-2, resource types are lower-case.** `resource-type` is now
|
|
lower-case words of `a-z`/`0-9` joined by single `-` or `_` (§6.1,
|
|
grammar, statute schema `resource_types` key pattern). `Ticket=PR42`,
|
|
`my--type=X` and `type-=X` are no longer canonical. New fixtures: p1-042
|
|
to p1-045.
|
|
|
|
- **SCP-3, type intake.** Address registry entries may carry
|
|
`intake_for: TYPE` (statute schema). This explicitly makes a function
|
|
address the intake for a declared resource type (§7). An opaque target
|
|
equal to a type name has no intake semantics without it.
|
|
|
|
- **SCP-5, intake auto-reply bounds.** New §14 item 10: auto-replies to
|
|
intake or interaction addresses SHOULD require an authenticated sender,
|
|
MUST be volume-bounded, and MUST NOT go to automated mail.
|
|
- **SCP-7, case-robust identifiers (recommendation).** §6.2: generators
|
|
SHOULD use identifiers whose meaning does not depend on case, and
|
|
receivers SHOULD match them case-insensitively. The statute field
|
|
`resource_id_case` is deferred to v0.2.
