build: update all crates to Rust 2024 edition

Largest change in the FFI crate.
With 2024 (but not 2021) edition unsafe code
inside unsafe functions should be marked separately
so we can mark exactly the code that is unsafe.
Some CFFI functions even have no unsafe code inside.

Most interesting change is that .strdup()
functions are not marked as unsafe anymore.
They are allocating memory and return raw pointers,
but there is nothing unsafe about it.
Only using the returned raw pointers is unsafe.
This way calls to .strdup() don't have to be marked
with unsafe{} blocks.

 # Changelog
 
+## [2.56.0] - 2026-07-21
+
+### API-Changes
+
+- [**breaking**] remove all oauth support and drop DC_LP_AUTH flags.
+  - removed oauth2 module, dc_get_oauth2_url FFI function, DC_LP_AUTH flags and configured/serverflags, and the oauth2 parameter/field from SMTP/IMAP clients, JSON-RPC interfaces, and CLI tools.
+
+also contains regenerated provider data after dropping oauth in the update script.
+
+### Features / Changes
+
+- do not set backup_time in exported databases.
+
+### Fixes
+
+- revert 207c2e6e4c1bec43204c3b8a46fcbbff67d54b3f because some users reported problems with it.
+
+### Miscellaneous Tasks
+
+- bump version to 2.56.0-dev.
+
+## [2.55.0] - 2026-07-20
+
+Minor release to fix CI because releasing 2.54.0 failed.
+
+### CI
+
+- Update Node version to 24.
+
+## [2.54.0] - 2026-07-20
+
+### API-Changes
+
+- [**breaking**] Deprecate `is_chatmail`.
+  - UIs should not behave differently for chatmail relays than for classical email servers; most usages of `is_chatmail` can be replaced by `force_encryption`.
+- [**breaking**] `delete_transport()` must not be used by UIs anymore. Instead, `set_transport_unpublished()` must be called when a user clicks on "Remove".
+- [**breaking**] `list_transports()` doesn't return unpublished relays anymore.
+  - UIs should use `list_transports()` rather than `list_transports_ex()`, because unpublished transports count as removed from the user point of view, and should not be shown in the relay list anymore.
+- deltachat-rpc-client: add `Account.set_transport_unpublished()`.
+- Add `MsgReadCountChanged` event.
+
+### Features / Changes
+
+- Implement support for populating and maintaining a list of default relays ([#8341](https://github.com/chatmail/core/pull/8341)).
+- Remove hidden relays automatically ([#8402](https://github.com/chatmail/core/pull/8402)).
+- Automatically remove oldest unpublished relay in order to make space when the user wants to add more; don't allow more than 5 relays overall ([#8428](https://github.com/chatmail/core/pull/8428)).
+- Add silent group changes messages as InNoticed, not InSeen.
+- Remove `?emailaddress` argument from autoconfig URL that is not using a dedicated domain.
+- Remove `imap::Session::sync_seen_flags()` ([#7742](https://github.com/chatmail/core/pull/7742)).
+- Use CAPABILITY response code if IMAP LOGIN command returns it.
+- Increase max idle timeout for iroh backup receiver to 60 seconds.
+
+### Fixes
+
+- Request MDNs for resent channel messages.
+- Make pre-messages w/o text want MDNs ([#8004](https://github.com/chatmail/core/pull/8004)).
+- Make truncated edited messages have HTML for receivers ([#8249](https://github.com/chatmail/core/pull/8249)).
+- Un-escape message footer marks in full messages (`get_html`) ([#8427](https://github.com/chatmail/core/pull/8427)).
+- Hide synced chat if we only know its visibility ([#8343](https://github.com/chatmail/core/pull/8343)).
+- Tombstone MDN before sending it ([#8252](https://github.com/chatmail/core/pull/8252)).
+- Recreate `imap_markseen` with `PRIMARY KEY` constraint.
+- Rerun the full securejoin protocol if the address was outdated ([#8358](https://github.com/chatmail/core/pull/8358)).
+- Return early from `receive_imf` to not tombstone Iroh-Node-Addr message if webxdc instance isn't found ([#8372](https://github.com/chatmail/core/pull/8372)).
+- Replace `last_added_location_id` with `last_added_location_timestamp`.
+- Do not put locations into pre-messages.
+- RUSTSEC-2026-0204 ([#8403](https://github.com/chatmail/core/pull/8403)).
+- Ensure public key signatures are not in the past compared to the public key.
+- Do not bubble up errors in IMAP candidate loop.
+- Do not log errors if full message is not available on any transport.
+- Apply reactions that arrived before the message at later time ([#8415](https://github.com/chatmail/core/pull/8415)).
+
+### Performance
+
+- Add timestamp to `msgs_index7` and speed up `Chatlist::try_load()` ([#7848](https://github.com/chatmail/core/pull/7848)).
+
+### CI
+
+- Update Rust to 1.97.1.
+- rrsync prepends the restricted upload path, we need to leave it out ([#8405](https://github.com/chatmail/core/pull/8405)).
+
+### Documentation
+
+- Update STYLE.md: macros should be used only when necessary ([#8410](https://github.com/chatmail/core/pull/8410)).
+- `create_group_chat_unencrypted()` may lead to chat split on the first device.
+
+### Refactor
+
+- Deprecate unused `SkipAutocrypt` param.
+- Remove commented out `RenderedEmail.envelope`.
+- Remove the ability to send messages with non-standard header protection.
+- Make `crate::pgp::symm_encrypt_message` non-async.
+- Move `ensure_secret_key_exists` into key.rs.
+- Improve comment ([#8366](https://github.com/chatmail/core/pull/8366)).
+- Remove `set_modseq()` function.
+- Remove unnecessary reference in format string.
+- Label the loop iterating over the candidates.
+- Remove `GROUP BY c.id` from chatlist queries.

+
+- Add JSON-RPC APIs for location streaming.
+- [**breaking**] Remove unused config `smtp_certificate_checks`.
+- Deprecate old server config keys that were replaced by `add_or_update_transport()`.
+- [**breaking**] remove `dc_delete_all_locations`.

+### Features / Changes
+
+- [**breaking**] Remove `mvbox_move` and `only_fetch_mvbox` configs. Transports have `folder` configuration to watch the folder other than `INBOX` as a replacement for `only_fetch_mvbox`. Non-chatmail transports no longer watch mvbox, each transport watches exactly one folder now.

+- Remove key fingerprint from `Context.get_info()`.
+- Mask local part of email addresses in `used_transport_settings`.
+
+### Fixes
+

+- Don't resort re-sent message to the bottom ([#8145](https://github.com/chatmail/core/pull/8145)).
+- Ensure that message being sent is added to the bottom ([#8027](https://github.com/chatmail/core/pull/8027)).
+- Don't receive message if a deletion request was received before ([#8143](https://github.com/chatmail/core/pull/8143)).
+- Emit `MsgsChanged`, not `IncomingMsg`, for messages only having special parts ([#8157](https://github.com/chatmail/core/pull/8157)).
+- Generate new pre-message `Message-ID` when forwarding.
+- use correct dir converting plaintext to HTML ([#8248](https://github.com/chatmail/core/pull/8248)).
+- hide connectivity HTML quota if not supported.
+- Delete pre-messages on the server for single-device chatmail transports ([#8240](https://github.com/chatmail/core/pull/8240)).

+
+- Flipped Exif orientations ([#8057](https://github.com/chatmail/core/pull/8057)).
+
+### Fixes
+

-
-Changes to the UIs
-------------------
-
-- The secondary self addresses (see below) are shown in the UI, but not editable.
-
-- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)
-
-Changes in the core
--------------------
-
-- [x] We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
-
-- [x] If the user does a reconfigure and changes the email address, the previous address is added as a secondary self address.
-
-  - don't forget to deduplicate secondary self addresses in case the user switches back and forth between addresses).
-
-  - The key stays the same.
-
-- [x] No changes for 1:1 chats, there simply is a new one. (This works since, contrary to group messages, messages sent to a 1:1 chat are not assigned to the group chat but always to the 1:1 chat with the sender. So it's not a problem that the new messages might be put into the old chat if they are a reply to a message there.)
-
-- [ ] When sending a message: If any of the secondary self addrs is in the chat's member list, remove it locally (because we just transitioned away from it). We add a log message for this (alternatively, a system message in the chat would be more visible).
-
-- [x] ([#3385](https://github.com/deltachat/deltachat-core-rust/pull/3385)) When receiving a message: If the key exists, but belongs to another address (we may want to benchmark this)
-  AND there is a `Chat-Version` header\
-  AND the message is signed correctly
-  AND the From address is (also) in the encrypted (and therefore signed) headers <sup>[[1]](#myfootnote1)</sup>\
-  AND the message timestamp is newer than the contact's `lastseen` (to prevent changing the address back when messages arrive out of order) (this condition is not that important since we will have eventual consistency even without it):
-
-  Replace the contact in _all_ groups, possibly deduplicate the members list, and add a system message to all of these chats.
-  
-  - Note that we can't simply compare the keys byte-by-byte, since the UID may have changed, or the sender may have rotated the key and signed the new key with the old one.
-
-<a name="myfootnote1">[1]</a>: Without this check, an attacker could replay a message from Alice to Bob. Then Bob's device would do an AEAP transition from Alice's to the attacker's address, allowing for easier phishing.
-
-<details>
-<summary>More details about this</summary>
-Suppose Alice sends a message to Evil (or to a group with both Evil and Bob). Evil then forwards the message to Bob, changing the From and To headers (and if necessary Message-Id) and replacing `addr=alice@example.org;` in the autocrypt header with `addr=evil@example.org;`.
-
-Then Bob's device sees that there is a message which is signed by Alice's key and comes from Evil's address and would do the AEAP transition, i.e. replace Alice with Evil in all groups and show a message "Alice changed their address from alice@example.org to evil@example.org". Disadvantages for Evil are that Bob's message will be shown on Alice's device, possibly creating confusion/suspicion, and that the usual "Setup changed for..." message will be shown the next time Evil sends a message (because Evil doesn't know Alice's private key).
-
-Possible mitigations:
-- if we make the AEAP device message sth. like "Automatically removed alice@example.org and added evil@example.org", then this will create more suspicion, making the phishing harder (we didn't talk about what what the wording should be at all yet).
-- Add something similar to replay protection to our Autocrypt implementation. This could be done e.g. by adding a second `From` header to the protected headers. If it's present, the receiver then requires it to be the same as the outer `From`, and if it's not present, we don't do AEAP --> **That's what we implemented**
-
-Note that usually a mail is signed by a key that has a UID matching the from address.
-
-  That's not mandatory for Autocrypt (and in fact, we just keep the old UID when changing the self address, so with AEAP the UID will actually be different than the from address sometimes)

-</details>
-
-### Notes:
-  
-- We treat protected and non-protected chats the same
-- We leave the aeap transition statement away since it seems not to be needed, makes things harder on the sending side, wastes some network traffic, and is worse for privacy (since more people know what old addresses you had).
-- As soon as we encrypt read receipts, sending a read receipt will be enough to tell a lot of people that you transitioned
-- AEAP will make the problem of inconsistent group state worse, both because it doesn't work if the message is unencrypted (even if the design allowed it, it would be problematic security-wise) and because some chat partners may have gotten the transition and some not. We should do something against this at some point in the future, like asking the user whether they want to add/remove the members to restore consistent group state.
-
-#### Downsides of this design:
-- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
-
-#### Upsides:
-- With this approach, it's easy to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
-- Faster transition: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.
-
-### Alternatives and old discussions/plans:
-
-- Change the contact instead of rewriting the group member lists. This seems to call for more trouble since we will end up with multiple contacts having the same email address.
-
-- If needed, we could add a header a) indicating that the sender did an address transition or b) listing all the secondary (old) addresses.  For now, there is no big enough benefit to warrant introducing another header and its processing on the receiver side (including all the necessary checks and handling of error cases). Instead, we only check for the `Chat-Version` header to prevent accidental transitions when an MUA user sends a message from another email address with the same key.
-
-- The condition for a transition temporarily was:
-
-  > When receiving a message: If we are going to assign a message to a chat, but the sender is not a member of this chat\
-  > AND the signing key is the same as the direct (non-gossiped) key of one of the chat members\
-  > AND ...
-
-  However, this would mean that in 1:1 messages can't trigger a transition, since we don't assign private messages to the parent chat, but always to the 1:1 chat with the sender.
-  
-<details>
-<summary>Some previous state of the discussion, which temporarily lived in an issue description</summary>
-Summarizing the discussions from https://github.com/deltachat/deltachat-core-rust/pull/2896, mostly quoting @hpk42:
-
-1. (DONE) At the time of configure we push the current primary to become a secondary. 
-
-2. When a message is sent out to a chat, and the message is encrypted, and we have secondary addresses, then we 
-  a) add a protected "AEAP-Replacement" header that contains all secondary addresses 
-  b) if any of the secondary addresses is in the chat's member list, we remove it and leave a system message that we did so
-3. When an encrypted message with a replacement header is received, replace the e-mail address of all secondary contacts (if they exist) with the new primary and drop a sysmessage in all chats the secondary is member off.  This might (in edge cases) result in chats that have two or more contacts with the same e-mail address.  We might ignore this for a first release and just log a warning.  Let's maybe not get hung up on this case before everything else works. 
-
-Notes: 
-- for now we will send out aeap replacement headers forever, there is no termination condition other than lack of secondary addresses.  I think that's fine for now.  Later on we might introduce options to remove secondary addresses but i wouldn't do this for a first release/PR. 
-- the design is resilient against changing e-mail providers from A to B to C and then back to A, with partially updated chats and diverging views from recipients/contacts on this transition.  In the end, you will have a primary and some secondaries, and when you start sending out messages everybody will eventually synchronize when they receive the current state of primaries/secondaries. 
-- of course on incoming message for need to check for each stated secondary address in the replacement header that it uses the same signature as the signature we verified as valid with the incoming message  **-->  Also we have to somehow make sure that the signing key was not just gossiped from some random other person in some group.**
-- there are no extra flags/columns in the database needed (i hope) 
-
-#### Downsides of the chosen approach:
-- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
-- There will be multiple contacts with the same address in the database. We will have to do something against this at some point.
-
-The most obvious alternative would be to create a new contact with the new address and replace the old contact in the groups.
-
-#### Upsides:
-- With this approach, it's easier to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
-- (Also, less important: Slightly faster transition: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.)
-- It's easier to implement (if too many problems turn up, we can still switch to another approach and didn't waste that much development time.)

-- The user is responsible that messages to the old address arrive at the new address, for example by configuring the old provider to forward all emails to the new one.

-Notes during implementing
-========================
-
-- As far as I understand the code, unencrypted messages are unsigned. So, the transition only works if both sides have the other side's key.
