## 4.0.0

# 3.0.3
 - Added feature to read password from external file (#120)

# 3.0.2

   failures.

## 3.0.0
 - [#57](https://github.com/logstash-plugins/logstash-input-jdbc/issues/57) New feature: Allow tracking by a column value rather than by last run time.  **This is a breaking change**, as users may be required to change from using `sql_last_start` to use `sql_last_value` in their queries.  No other changes are required if you've been using time-based queries.  See the documentation if you wish to use an incremental column value to track updates to your tables.

## 2.0.3
 - Added ability to configure timeout
 - Added catch-all configuration option for any other options that Sequel lib supports

## 2.0.0

   instead of using Thread.raise on the plugins' threads. Ref: https://github.com/elastic/logstash/pull/3895
 - Dependency on logstash-core update to 2.0

## 1.0.0
