+
+- introduce per-contact profile images to send out 
+  own profile image heuristically, and fix sending
+  out of profile images in "in-prepare" groups. 
+  this also extends the Chat-spec that is maintained
+  in core to specify Chat-Group-Image and Chat-Group-Avatar
+  headers. thanks @r10s and @hpk42.
+
+- fix merging of protected headers from the encrypted
+  to the unencrypted parts, now not happening recursively
+  anymore.  thanks @hpk and @r10s
+
+- fix/optimize autocrypt gossip headers to only get 
+  sent when there are more than 2 people in a chat. 
+  thanks @link2xt
+
+- fix displayname to use the authenticated name 
+  when available (displayname as coming from contacts 
+  themselves). thanks @simon-laux
+
+- introduce preliminary support for offline autoconfig 
+  for nauta provider. thanks @hpk42 @r10s
+
+## 1.0.0-beta.15
+
+- fix #994 attachment appeared doubled in chats (and where actually
+  downloaded after smtp-send). @hpk42
+
+## 1.0.0-beta.14
+
+- fix packaging issue with our rust-email fork, now we are tracking
+  master again there. hpk42
+
+## 1.0.0-beta.13
+
+- fix #976 -- unicode-issues in display-name of email addresses. @hpk42
+
+- fix #985 group add/remove member bugs resulting in broken groups.  @hpk42
+
+- fix hanging IMAP connections -- we now detect with a 15second timeout
+  if we cannot terminate the IDLE IMAP protocol. @hpk42 @link2xt
+
+- fix incoming multipart/mixed containing html, to show up as
+  attachments again.  Fixes usage for simplebot which sends html
+  files for users to interact with the bot. @adbenitez @hpk42 
+
+- refinements to internal autocrypt-handling code, do not send
+  prefer-encrypt=nopreference as it is the default if no attribute
+  is present.  @linkxt 
+
+- simplify, modularize and rustify several parts 
+  of dc-core (general WIP). @link2xt @flub @hpk42 @r10s
+
+- use async-email/async-smtp to handle SMTP connections, might
+  fix connection/reconnection issues. @link2xt 
+
+- more tests and refinements for dealing with blobstorage @flub @hpk42 
+
+- use a dedicated build-server for CI testing of core PRs
+
+
+## 1.0.0-beta.12
+
+- fix python bindings to use core for copying attachments to blobdir
+  and fix core to actually do it. @hpk42
+
+## 1.0.0-beta.11
+
+- trigger reconnect more often on imap error states.  Should fix an 
+  issue observed when trying to empty a folder.  @hpk42
+
+- un-split qr tests: we fixed qr-securejoin protocol flakyness 
+  last weeks. @hpk42
+
+## 1.0.0-beta.10
+
+- fix grpid-determination from in-reply-to and references headers. @hpk42
+
+- only send Autocrypt-gossip headers on encrypted messages. @dignifiedquire
+
+- fix reply-to-encrypted message to also be encrypted. @hpk42
+
+- remove last unsafe code from dc_receive_imf :) @hpk42
+
+- add experimental new dc_chat_get_info_json FFI/API so that desktop devs
+  can play with using it. @jikstra
+
+- fix encoding of subjects and attachment-filenames @hpk42
+  @dignifiedquire . 
+
+## 1.0.0-beta.9
+
+- historic: we now use the mailparse crate and lettre-email to generate mime
+  messages.  This got rid of mmime completely, the C2rust generated port of the libetpan 
+  mime-parse -- IOW 22KLocs of cumbersome code removed! see 
+  https://github.com/deltachat/deltachat-core-rust/pull/904#issuecomment-561163330
+  many thanks @dignifiedquire for making everybody's life easier 
+  and @jonhoo (from rust-imap fame) for suggesting to use the mailparse crate :) 
+
+- lots of improvements and better error handling in many rust modules 
+  thanks @link2xt @flub @r10s, @hpk42 and @dignifiedquire 
+
+- @r10s introduced a new device chat which has an initial
+  welcome message.  See 
+  https://c.delta.chat/classdc__context__t.html#a1a2aad98bd23c1d21ee42374e241f389
+  for the main new FFI-API.
+
+- fix moving self-sent messages, thanks @r10s, @flub, @hpk42
+
+- fix flakyness/sometimes-failing verified/join-protocols, 
+  thanks @flub, @r10s, @hpk42
+
+- fix reply-to-encrypted message to keep encryption 
+
+- new DC_EVENT_SECUREJOIN_MEMBER_ADDED event 
+
+- many little fixes and rustifications (@link2xt, @flub, @hpk42)
+
+
+## 1.0.0-beta.8
+
+- now uses async-email/async-imap as the new base 
+  which makes imap-idle interruptible and thus fixes
+  several issues around the imap thread being in zombie state . 
+  thanks @dignifiedquire, @hpk42 and @link2xt. 
+
+- fixes imap-protocol parsing bugs that lead to infinitely
+  repeated crashing while trying to receive messages with
+  a subjec that contained non-utf8. thanks @link2xt
+
+- fixed logic to find encryption subkey -- previously 
+  delta chat would use the primary key for encryption
+  (which works with RSA but not ECC). thanks @link2xt
+
+- introduce a new device chat where core and UIs can 
+  add "device" messages.  Android uses it for an initial
+  welcome message. thanks @r10s
+
+- fix time smearing (when two message are virtually send
+  in the same second, there would be misbehaviour because
+  we didn't persist smeared time). thanks @r10s
+
+- fix double-dotted extensions like .html.zip or .tar.gz  
+  to not mangle them when creating blobfiles.  thanks @flub
+
+- fix backup/exports where the wrong sql file would be modified,
+  leading to problems when exporting twice.  thanks @hpk42
+
+- several other little fixes and improvements 
+
+
 ## 1.0.0-beta.7

 # Continuous Integration Scripts for Delta Chat
 
-Continuous Integration is run through CircleCI
-but is largely independent of it. 
+Continuous Integration, run through CircleCI and an own build machine.
+
+## Description of scripts 
+
+- `../.circleci/config.yml` describing the build jobs that are run
+  by Circle-CI
+
+- `remote_tests_python.sh` rsyncs to a build machine and runs
+  `run-python-test.sh` remotely on the build machine. 
+
+- `remote_tests_rust.sh` rsyncs to the build machine and runs
+  `run-rust-test.sh` remotely on the build machine. 
+
+- `doxygen/Dockerfile` specifies an image that contains
+  the doxygen tool which is used by `run-doxygen.sh` 
+  to generate C-docs which are then uploaded 
+  via `ci_upload.sh` to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
+  (and the master branch is linked to https://c.delta.chat proper). 
 
 
-## Generating docker containers for performing build step work 
+## Triggering runs on the build machine locally (fast!)
 
-All tests, docs and wheel building is run in docker containers:
+There is experimental support for triggering a remote Python or Rust test run 
+from your local checkout/branch. You will need to be authorized to login to 
+the build machine (ask your friendly sysadmin on #deltachat freenode) to type::
 
-- **coredeps/Dockerfile** specifies an image that contains all 
-  of Delta Chat's core dependencies as linkable libraries. 
-  It also serves to run python tests and build wheels 
-  (binary packages for Python). 
+    ci_scripts/manual_remote_tests.sh rust
+    ci_scripts/manual_remote_tests.sh python
 
-- **doxygen/Dockerfile** specifies an image that contains
-  the doxygen tool which is used to generate C-docs. 
+This will **rsync** your current checkout to the remote build machine 
+(no need to commit before) and then run either rust or python tests. 
 
-To run tests locally you can pull existing images from "docker.io",
-the hub for sharing Docker images::
+# Outdated files (for later re-use)
 
-    docker pull deltachat/coredeps
-    docker pull deltachat/doxygen 
+`coredeps/Dockerfile` specifies an image that contains all 
+of Delta Chat's core dependencies. It used to run 
+python tests and build wheels (binary packages for Python)
 
-or you can build the docker images yourself locally
+You can build the docker images yourself locally
 to avoid the relatively large download:: 
  
     cd ci_scripts  # where all CI things are 
     docker build -t deltachat/coredeps docker-coredeps
     docker build -t deltachat/doxygen docker-doxygen 
-
-## ci_run.sh (main entrypoint called by circle-ci)
-
-Once you have the docker images available 
-you can run python testing, documentation generation 
-and building binary wheels:: 
-
-    sh DOCS=1 TESTS=1 ci_scripts/ci_run.sh 
-    
-## ci_upload.sh (uploading artifacts on success) 
-
-- python docs to `https://py.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
-
-- doxygen docs to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
-
-- python wheels to `https://m.devpi.net/dc/<BRANCH>`
-  so that you install fully self-contained wheels like this:
-  `pip install -U -i https://m.devpi.net/dc/<BRANCH> deltachat`
-

+- Alice and Bob are in a two-member group
+
+- Alice adds Carol, concurrently Bob adds Doris
+
+- Carol will see a three-member group (Alice, Bob, Carol),
+  Doris will see a different three-member group (Alice, Bob, Doris),
+  and only Alice and Bob will have all four members.
+
+Note that for verified groups any mitigation mechanism likely
+needs to make all clients to know who originally added a member.
+
+
+solution: memorize+attach (possible encrypted) chat-meta mime messages
+----------------------------------------------------------------------
+
+For reference, please see https://github.com/deltachat/deltachat-core-rust/blob/master/spec.md#add-and-remove-members how MemberAdded/Removed messages are shaped.
+
+
+- All Chat-Group-Member-Added/Removed messages are recorded in their
+  full raw (signed and encrypted) mime-format in the DB
+
+- If an incoming member-add/member-delete messages has a member list
+  which is, apart from the added/removed member, not consistent
+  with our own view, broadcast a "Chat-Group-Member-Correction" message to
+  all members, attaching the original added/removed mime-message for all mismatching
+  contacts.  If we have no relevant add/del information, don't send a
+  correction message out.
+
+- Upong receiving added/removed attachments we don't do the
+  check_consistency+correction message dance.
+  This avoids recursion problems and hard-to-reason-about chatter.
+
+Notes:
+
+- mechanism works for both encrypted and unencrypted add/del messages
+
+- we already have a "mime_headers" column in the DB for each incoming message.
+  We could extend it to also include the payload and store mime unconditionally
+  for member-added/removed messages.
+
+- multiple member-added/removed messages can be attached in a single
+  correction message
+
+- it is minimal on the number of overall messages to reach group consistency
+  (best-case: no extra messages, the ABCD case above: max two extra messages)
+
+- somewhat backward compatible: older clients will probably ignore
+  messages which are signed by someone who is not the outer From-address.
+
+- the correction-protocol also helps with dropped messages.  If a member
+  did not see a member-added/removed message, the next member add/removed
+  message in the group will likely heal group consistency for this member.
+
+- we can quite easily extend the mechanism to also provide the group-avatar or
+  other meta-information.
+
+Discussions of variants
+++++++++++++++++++++++++
+
+- instead of acting on MemberAdded/Removed message we could send
+  corrections for any received message that addresses inconsistent group members but
+  a) this would delay group-membership healing
+  b) could lead to a lot of members sending corrections
+
+- instead of broadcasting correction messages we could only send it to
+  the sender of the inconsistent member-added/removed message.
+  A receiver of such a correction message would then need to forward
+  the message to the members it thinks also have an inconsistent view.
+  This sounds complicated and error-prone.  Concretely, if Alice
+  receives Bob's "Member-added: Doris" message, then Alice
+  broadcasting the correction message with "Member-added: Carol"
+  would reach all four members, healing group consistency in one step.
+  If Bob meanwhile receives Alice's "Member-Added: Carol" message,
+  Bob would broadcast a correction message to all four members as well.
+  (Imagine a situation where Alice/Bob added Carol/Doris
+  while both being in an offline or bad-connection situation).
+
+
+solution2: repeat member-added/removed messages
+---------------------------------------------------
+
+Introduce a new Chat-Group-Member-Changed header and deprecate Chat-Group-Member-Added/Removed
+but keep sending out the old headers until the new protocol is sufficiently deployed.
+
+The new Chat-Group-Member-Changed header contains a Time-to-Live number (TTL)
+which controls repetition of the signed "add/del e-mail address" payload.
+
+Example::
+
+    Chat-Group-Member-Changed: TTL add "somedisplayname" someone@example.org
+        owEBYQGe/pANAwACAY47A6J5t3LWAcsxYgBeTQypYWRkICJzb21lZGlzcGxheW5h
+        bWUiIHNvbWVvbmVAZXhhbXBsZS5vcmcgCokBHAQAAQIABgUCXk0MqQAKCRCOOwOi
+        ebdy1hfRB/wJ74tgFQulicthcv9n+ZsqzwOtBKMEVIHqJCzzDB/Hg/2z8ogYoZNR
+        iUKKrv3Y1XuFvdKyOC+wC/unXAWKFHYzY6Tv6qDp6r+amt+ad+8Z02q53h9E55IP
+        FUBdq2rbS8hLGjQB+mVRowYrUACrOqGgNbXMZjQfuV7fSc7y813OsCQgi3tjstup
+        b+uduVzxCp3PChGhcZPs3iOGCnQvSB8VAaLGMWE2d7nTo/yMQ0Jx69x5qwfXogTk
+        mTt5rOJyrosbtf09TMKFzGgtqBcEqHLp3+mQpZQ+WHUKAbsRa8Jc9DOUOSKJ8SNM
+        clKdskprY+4LY0EBwLD3SQ7dPkTITCRD
+        =P6GG
+
+TTL is set to "2" on an initial Chat-Group-Member-Changed add/del message.
+Receivers will apply the add/del change to the group-membership,
+decrease the TTL by 1, and if TTL>0 re-sent the header.
+
+The "add|del e-mail address" payload is pgp-signed and repeated verbatim.
+This allows to propagate, in a cryptographically secured way,
+who added a member. This is particularly important for allowing
+to show in verified groups who added a member (planned).
+
+Disadvantage to solution 1:
+
+- requires to specify encoding and precise rules for what/how is signed.
+
+- causes O(N^2) extra messages
+
+- Not easily extendable for other things (without introducing a new
+  header / encoding)

+
+simplify/streamline mark-seen/delete/move/send-mdn job handling
+---------------------------------------------------------------
+
+Idea: Introduce a new "msgwork" sql table that looks very
+much like the jobs table but has a primary key "msgid"
+and no job id and no foreign-id anymore. This opens up
+bulk-processing by looking at the whole table and combining
+flag-setting to reduce imap-roundtrips and select-folder calls.
+
+Concretely, these IMAP jobs:
+
+    DeleteMsgOnImap
+    MarkseenMsgOnImap
+    MoveMsg
+
+Would be replaced by a few per-message columns in the new msgwork table:
+
+- needs_mark_seen: (bool) message shall be marked as seen on imap
+- needs_to_move: (bool) message should be moved to mvbox_folder
+- deletion_time: (target_time or 0) message shall be deleted at specified time
+- needs_send_mdn: (bool) MDN shall be sent
+
+The various places that currently add the (replaced) jobs
+would now add/modify the respective message record in the message-work table.
+
+Looking at a single message-work entry conceptually looks like this::
+
+    if msg.server_uid==0:
+        return RetryLater  # nothing can be done without server_uid
+
+    if msg.deletion_time > current_time:
+        imap.mark_delete(msg)  # might trigger early exit with a RetryLater/Failed
+        clear(needs_deletion)
+        clear(mark_seen)
+
+    if needs_mark_seen:
+        imap.mark_seen(msg)    # might trigger early exit with a RetryLater/Failed
+        clear(needs_mark_seen)
+
+    if needs_send_mdn:
+        schedule_smtp_send_mdn(msg)
+        clear(needs_send_mdn)
+
+    if any_flag_set():
+        retrylater
+    # remove msgwork entry from table
+
+
+Notes/Questions:
+
+- it's unclear how much we need per-message retry-time tracking/backoff
+
+- drafting bulk processing algo is useful before
+  going for the implementation, i.e. including select_folder calls etc.
+
+- maybe it's better to not have bools for the flags but
+
+  0 (no change)
+  1 (set the imap flag)
+  2 (clear the imap flag)
+
+  and design such that we can cover all imap flags.
+
+- It might not be neccessary to keep needs_send_mdn state in this table
+  if this can be decided rather when we succeed with mark_seen/mark_delete.

-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses

-   as of the date such litigation is filed.
-
-4. Redistribution. You may reproduce and distribute copies of the
-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or

-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution

-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.

-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,

-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the

-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-Installing bindings from source
-===============================
+Running tests
+=============
 
-If you can't use "binary" method above then you need to compile
-to core deltachat library::
-
-    git clone https://github.com/deltachat/deltachat-core-rust
-    cd deltachat-core-rust
-    cd python
-
-If you don't have one active, create and activate a python "virtualenv":
-
-    python virtualenv venv  # or python -m venv
-    source venv/bin/activate
-
-Afterwards ``which python`` tells you that it comes out of the "venv"
-directory that contains all python install artifacts. Let's first
-install test tools::
-
-    pip install pytest pytest-timeout pytest-rerunfailures requests
-
-then cargo-build and install the deltachat bindings::
-
-    python install_python_bindings.py
-
-The bindings will be installed in release mode but with debug symbols.
-The release mode is necessary because some tests generate RSA keys
-which is prohibitively slow in debug mode.
-
-After successful binding installation you can finally run the tests::
+After successful binding installation you can install a few more
+Python packages before running the tests::
 
+    python -m pip install pytest pytest-xdist pytest-timeout pytest-rerunfailures requests
     pytest -v tests
 
-.. note::
+This will run all "offline" tests and skip all functional
+end-to-end tests that require accounts on real e-mail servers.
 
-    Some tests are sometimes failing/hanging because of
-    https://github.com/deltachat/deltachat-core-rust/issues/331
-    and
-    https://github.com/deltachat/deltachat-core-rust/issues/326
+.. _livetests:
+
+running "live" tests with temporary accounts
+---------------------------------------------
+
+If you want to run live functional tests you can set ``DCC_NEW_TMP_EMAIL``::
+
+    export DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=1h_4w4r8h7y9nmcdsy
+
+With this, pytest runs create ephemeral e-mail accounts on the http://testrun.org server.
+These accounts exists for one 1hour and then are removed completely.
+One hour is enough to invoke pytest and run all offline and online tests:
+
+    pytest
+
+    # or if you have installed pytest-xdist for parallel test execution
+    pytest -n6
+
+Each test run creates new accounts.

-If you want to run "liveconfig" functional tests you can set

+Installing bindings from source (Updated: July 2020)
+=========================================================
 
-- a particular https-url that you can ask for from the delta
-  chat devs.
+Install Rust and Cargo first.
+The easiest is probably to use `rustup <https://rustup.rs/>`_.
 
-- or the path of a file that contains two lines, each describing
-  via "addr=... mail_pw=..." a test account login that will
-  be used for the live tests.
+Bootstrap Rust and Cargo by using rustup::
 
-With ``DCC_PY_LIVECONFIG`` set pytest invocations will use real
-e-mail accounts and run through all functional "liveconfig" tests.
+   curl https://sh.rustup.rs -sSf | sh
 
+Then clone the deltachat-core-rust repo::
+
+   git clone https://github.com/deltachat/deltachat-core-rust
+   cd deltachat-core-rust
+
+To install the Delta Chat Python bindings make sure you have Python3 installed.
+E.g. on Debian-based systems `apt install python3 python3-pip
+python3-venv` should give you a usable python installation.
+
+Ensure you are in the deltachat-core-rust/python directory, create the
+virtual environment and activate it in your shell::
+
+   cd python
+   python3 -m venv venv  # or: virtualenv venv
+   source venv/bin/activate
+
+You should now be able to build the python bindings using the supplied script::
+
+   python install_python_bindings.py
+
+The core compilation and bindings building might take a while,
+depending on the speed of your machine.
+The bindings will be installed in release mode but with debug symbols.
+The release mode is currently necessary because some tests generate RSA keys
+which is prohibitively slow in non-release mode.
