## Version history (last 5 releases)

### 3.17 — 2019-02-16

It is hard to believe it has been a few years since the last version of SCraMP! In a reflection of the years gone by, this version contains "under the hood" code updates and modernization that should make it run better on newer devices, without looking much different to end users. Additionally, I've added a thank you to the newest source of grant support for this, and related fishing vessel safety app work, from the Northeast Center for Occupational Health and Safety.

### 3.16 — 2015-01-24

Bug fixes

### 3.15 — 2014-08-29

Added a feature to auto-save data while recording.

### 3.14 — 2014-07-07

Bug fixes

### 3.13 — 2013-10-23

Version 3.13 features two new warning metrics.  One metric helps identify potential parametric roll conditions by comparing roll period to pitch period and providing audible and visual warnings when this ratio approaches 2.  The second metric helps identify heave periods and accelerations that may exacerbate motion sickness, specifically, periods between 5-6s with a heave acceleration larger than 0.2g.
