# Version UPCOMING (...)
|
||||
# Version 0.8.0 (2016-12-31)
|
||||
|
||||
* BREAKING CHANGE: The `FromSql` trait has been redesigned. It now requires a single, safe
|
||||
method instead of the previous definition which required implementing one or two unsafe
|
||||
methods.
|
||||
* BREAKING CHANGE: The `ToSql` trait has been redesigned. It can now be implemented without
|
||||
`unsafe`, and implementors can choose to return either borrowed or owned results.
|
||||
* BREAKING CHANGE: The closure passed to `query_row`, `query_row_and_then`, `query_row_safe`,
|
||||
and `query_row_named` now expects a `&Row` instead of a `Row`. The vast majority of calls
|
||||
to these functions will probably not need to change; see
|
||||
https://github.com/jgallagher/rusqlite/pull/184.
|
||||
* BREAKING CHANGE: A few cases of the `Error` enum have sprouted additional information
|
||||
(e.g., `FromSqlConversionFailure` now also includes the column index and the type returned
|
||||
by SQLite).
|
||||
* Added `#[deprecated(since = "...", note = "...")]` flags (new in Rust 1.9 for libraries) to
|
||||
all deprecated APIs.
|
||||
* Added `query_row` convenience function to `Statement`.
|
||||
* Added `bundled` feature which will build SQLite from source instead of attempting to link
|
||||
against a SQLite that already exists on the system.
|
||||
* Fixed a bug where using cached prepared statements resulted in attempting to close a connection
|
||||
failing with `DatabaseBusy`; see https://github.com/jgallagher/rusqlite/issues/186.

Rusqlite is an ergonomic wrapper for using SQLite from Rust. It attempts to expose

an interface similar to [rust-postgres](https://github.com/sfackler/rust-postgres). View the full
