In This Release
A special thanks to the amazing volunteer translators and testers who made this release possible.
Cwtch 1.16.1 is small update in scope, but reflected a large amount of work under the surface to improve and modernize our dependency stack.
- New Features:
- New Encrypted Database Backend - The Cwtch Team have invested in updating our encrypted database backend. Prior to 1.16.1 Cwtch relied on an outdated go wrapper for sqlcipher with libTomCrypt for encryption. This dependency had not received updates in many years, and was lagging behind sqlcipher and sqlite releases. We have now forked and adopted this dependency under the name go-sqlcipher, invested in new maintenance scripts that make updating easier, and migrated the C-based crypto backed to a new memory-safe one based on standard, and audited go crypto.
- Memory Tagging Extension Safe - With the upgrade of our encrypted database backed we also took the opportunity to replace the less than ideal usage of GoString from the libSqlite3 go dependency. These calls are now wrapped with a go function that ensure safe memory reads and should no longer result in Cwtch being killed when MTE in enabled on ARM platforms.
- Bug Fixes / Improvements:
- Cwtch is now based on Flutter 3.29
- Fixes to retry cooldown to prevent long-delays when an initial connection attempt fails. This should result in faster connections to online friends.
- Accessibility / UX:
- Core translations for Brazilian Portuguese, Danish , Dutch, French, German, Italian, Norwegian , Romanian , Russian, Polish, Slovak, Spanish, Swahili, Swedish, Turkish, and Welsh
- Partial translations for Korean (41%), Japanese (26%), , Luxembourgish (19%), Greek (15%), Uzbek (9%), and Portuguese (5%)
