hi all,
Rust-core is getting more and more stable and is now part of recurring development 
releases for Desktop, Android and iOS.  Our overall release is tracked in
this github project: 
https://github.com/orgs/deltachat/projects/15
Dev releases are generally published to the respective github-releases pages.
https://github.com/deltachat/deltachat-desktop/releases
https://github.com/deltachat/deltachat-android/releases
https://github.com/deltachat/deltachat-ios/releases
and for iOS they also go to Testflight from time to time. 
If you can help with testing releases out, filing bug issues/PRs and 
checking if things are fixed ... that's much appreciated, also by 
the many people who you thus help to avoid encountering the error ;) 
below you find a note on the cleanup efforts after Rust-core started
existing from a C2Rust translated code base.  We've come a looong way!
cheers,
holger
Rust-core cleanup effort status
-------------------------------
We got rid a few days ago of the last "OK_TO_CONTINUE" patterns
which came from C-level "goto".  So that column is gone and we now have
"unsafe fn" which indicate that a whole function is marked as unsafe. 
We try to push this down to the actual function parts that are unsafe. 
In any case, the current stats now look like this: 
dc_tools.rs               unsafe:  29 free:  10 unsafe-fn:  11 chars: 100
wrapmime.rs               unsafe:  49 free:   1 unsafe-fn:   2 chars:  12
dc_mimeparser.rs          unsafe:  22 free:   5 unsafe-fn:  10 chars:  27
dc_receive_imf.rs         unsafe:  13 free:   3 unsafe-fn:  13 chars:  12
e2ee.rs                   unsafe:  27 free:   6 unsafe-fn:   0 chars:   5
pgp.rs                    unsafe:   1 free:   0 unsafe-fn:   1 chars:  19
imex.rs                   unsafe:   7 free:   3 unsafe-fn:   0 chars:   3
aheader.rs                unsafe:   8 free:   0 unsafe-fn:   0 chars:   3
mimefactory.rs            unsafe:   5 free:   2 unsafe-fn:   1 chars:   3
error.rs                  unsafe:   0 free:   0 unsafe-fn:   0 chars:   5
dc_strencode.rs           unsafe:   1 free:   2 unsafe-fn:   0 chars:   2
stock.rs                  unsafe:   2 free:   1 unsafe-fn:   0 chars:   1

lib.rs                    unsafe:   1 free:   0 unsafe-fn:   0 chars:   0
key.rs                    unsafe:   1 free:   0 unsafe-fn:   0 chars:   0
total unsafe: 173
total free: 35
total unsafe-fn: 39
total c_chars: 192
The incoming-message (mime-parsing and processing) pipeline remains the last 
bigger worry. We have overall 4.83% unsafe out of 20538 overall code lines in 
rust-core, according to cargo-count.
