title: Pebble SDK 4.1.2 and 4.1.3 - Changelog
date: 2016-10-04
---

4.1.2 is a hotfix for [firmware 4.1](/sdk/changelogs/4.1/).
4.1.3 removes some debug apps that were inadvertently included in 4.1.2.

### Changes to Firmware

* Fixed an issue where the Rocky.js `Date` constructor did not work for dates in October
  on a leap year. This also fixes an issue where Tic-Toc would fail after one minute.

### Changes to SDK

None.

### Known issues

* ``health_service_metric_accessible`` always returns `false` when
  checking the accessibility of ``HealthMetricHeartRateBPM``.
  Instead, use
  `health_service_metric_aggregate_averaged_accessible(HealthMetricHeartRateBPM, time_start, time_end, HealthAggregationAvg, HealthServiceTimeScopeOnce)`
