version = "0.27.0"

```
* When using any of the `bundled` features, the build script will honor `SQLITE_MAX_VARIABLE_NUMBER` and `SQLITE_MAX_EXPR_DEPTH` variables. It will also honor a `LIBSQLITE_FLAGS` variable, which can have a format like `"-USQLITE_ALPHA -DSQLITE_BETA SQLITE_GAMMA ..."`. That would disable the `SQLITE_ALPHA` flag, and set the `SQLITE_BETA` and `SQLITE_GAMMA` flags. (The initial `-D` can be omitted, as on the last one.)
* When using any of the `bundled` features, the build script will honor `SQLITE_MAX_VARIABLE_NUMBER` and `SQLITE_MAX_EXPR_DEPTH` variables. It will also honor a `LIBSQLITE3_FLAGS` variable, which can have a format like `"-USQLITE_ALPHA -DSQLITE_BETA SQLITE_GAMMA ..."`. That would disable the `SQLITE_ALPHA` flag, and set the `SQLITE_BETA` and `SQLITE_GAMMA` flags. (The initial `-D` can be omitted, as on the last one.)
* When using `bundled-sqlcipher` (and not also using `bundled-sqlcipher-vendored-openssl`), `libsqlite3-sys` will need to
link against crypto libraries on the system. If the build script can find a `libcrypto` from OpenSSL or LibreSSL (it will consult `OPENSSL_LIB_DIR`/`OPENSSL_INCLUDE_DIR` and `OPENSSL_DIR` environment variables), it will use that. If building on and for Macs, and none of those variables are set, it will use the system's SecurityFramework instead.
