* Change the way in which callback chains can be halted.
|
|
|
|
|
|
|
|
The preferred method to halt a callback chain from now on is to explicitly
|
|
|
|
`throw(:abort)`.
|
|
|
|
In the past, returning `false` in an ActiveRecord `before_` callback had the
|
|
|
|
side effect of halting the callback chain.
|
|
|
|
This is not recommended anymore and, depending on the value of the
|
|
|
|
`config.active_support.halt_callback_chains_on_return_false` option, will
|
|
|
|
either not work at all or display a deprecation warning.

In 5.5, when you insert `2014-08-17 12:30:00.999999` the fractional part
|
|
|
|
is ignored. In 5.6, it's rounded to `2014-08-17 12:30:01`:

SQLite3 and PostgreSQL adapters was only returning the first field of the key.

composite primary keys.
