Hi,

[DSI](https://datashield.github.io/DSI) 1.4.0 (available in the CRAN) has been released with the following additional features:

- `failSafe` parameter added to [datashield.login()](https://datashield.github.io/DSI/reference/datashield.login.html), to automatically ignore servers which connection failed.
- `success` and `error` callback function parameters added to [datashield.aggregate()](https://datashield.github.io/DSI/reference/datashield.aggregate.html) and [datashield.assign()](https://datashield.github.io/DSI/reference/datashield.assign.html) (and sister assign functions), for Datashield client package developers willing to handle server operation success or failure as soon as they happen.

These changes are backward compatible with end-user code and do not affect packages implementing this API (such as DSOpal or DSLite). Upgrade to DSI 1.4.0 is then safe.

Regards  
Yannick
