I have a WIP patch that updates Rust upto 1.43.1, but it's blocked on a LLVM 9 patch backport I haven't had time to prepare yet. I won't have the time to look into it properly right now, but here are the relevant links: https://github.com/rust-lang/llvm-project/commit/7d5e7c023053660ffe494d72ce471e48ecc7f49b https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959877 https://github.com/rust-lang/llvm-project/pull/43 Regards, Jakub Kądziołka [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 833 bytes --]

I also bumped rust-xml-rs-0.8 to 0.8.3. -- Efraim Flashner <efraim@flashner.co.il> אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 833 bytes --]
