Breaking changes

* **Postal:** Require Python 3.9 or later for Postal tracking webhook support.
  (Postal's signature verification uses the "cryptography" package, which is no
  longer reliably installable with Python 3.8.)
Fixes

* **Mailjet:** Avoid a Mailjet API error when sending an inline image without a
  filename. (Anymail now substitutes ``"attachment"`` for the missing filename.)
  (Thanks to `@chickahoona`_ for reporting the issue.)


Mailjet: Fix a JSON parsing error on Mailjet 429 "too many requests" API

responses. (Thanks to @rodrigondec_ for reporting the issue.)


Postmark: Fix a parsing error when Postmark indicates a sent message has

been delayed, which can occur if your message stream is paused or throttled or

when Postmark is experiencing service issues. These messages will now report

"queued" in the anymail_status (rather than throwing an error or reporting

"sent"). (Thanks to @jmduke_ for reporting the issue.)


Postmark: Fix an error in inbound handling with long email address display

names that include non-ASCII characters.


SendGrid: Improve handling of non-string values in merge_data when using

legacy templates or inline merge fields. To avoid a confusing SendGrid API error

message, Anymail now converts numeric merge data values to strings, but will raise

an AnymailSerializationError for other non-string data in SendGrid substitutions.

(SendGrid's newer dynamic transactional templates do not have this limitation.)

(Thanks to @PlusAsh_ for reporting the issue.)


Other




Officially support Django 5.2.


Resend: Remove Anymail's workaround for an earlier Resend API bug with
punctuation in address display names. Resend has fixed the bug.
