## v2.0.2-rc ### BREAKING CHANGES * Refactored `config.json` - will need to verify configuration settings prior to mounting ### Issues * \#12 \[Unit Test\] Complete all providers unit tests * \#14 \[Unit Test\] SQLite mini-ORM unit tests and cleanup * \#16 Add support for bucket name in Sia provider * \#17 Update to common c++ build system * A single 64-bit Linux Jenkins server is used to build all Linux and Windows versions * All dependency sources are now included * MSVC is no longer supported * MSYS2 is required for building Windows binaries on Windows * OS X support is temporarily disabled * \#19 \[bug\] Rename file is broken for files that are existing * \#23 \[bug\] Incorrect file size displayed while upload is pending * \#24 RocksDB implementations should be transactional * \#25 Writes should block when maximum cache size is reached * \#26 Complete ring buffer and direct download support ### Changes from v2.0.1-rc * Ability to choose between RocksDB and SQLite databases * Added direct reads and implemented download fallback * Corrected file times on S3 and Sia providers * Corrected handling of `chown()` and `chmod()` * Fixed erroneous download of chunks after resize Reviewed-on: #27
