## 1.5.2 (2021-01-10)

- Maintainer change (Folashade Daniel; fdaniel@microsoft.com)

## 1.5.1 (2020-10-12)

- Maintainer change (Michelle Wallig; Michelle.Wallig@microsoft.com)

## 1.5.0 (2020-03-29)

- Changed the default value for the `foreachDoparLocal` system option to TRUE.

## 1.4.8 (2020-02-04)

<ul>
<li>Added preliminary support for evaluating `%dopar%` expressions in a local environment, when a sequential backend is used. This addresses a long-standing inconsistency in the behaviour of `%dopar%` with parallel and sequential backends, where the latter would evaluate the loop body in the global environment by default. The behaviour of `%dopar%` can be controlled by setting

`options(foreachDoparLocal=TRUE|FALSE)`

or equivalently via the system environment variable

`R_FOREACH_DOPAR_LOCAL=TRUE|FALSE`

with the R option taking its value from the environment variable. If both are set, the former overrides the latter. The current default value is FALSE, which retains the pre-existing behaviour. It is intended that over time this will be changed to TRUE.

A side-effect of this change is that the behaviour of `%do%` and `%dopar%` will (eventually) be different for a sequential backend. See https://github.com/RevolutionAnalytics/foreach/issues/3 for more discussion on this issue.</li>

<li> Updated tooling used for development. None of these changes should have any effect on package behaviour.
<ul>
<li>Use Roxygen for documentation</li>
<li>Use testthat for unit tests</li>
<li>Convert vignettes to Rmarkdown format (and output HTML instead of PDF)</li>
<li>Convert NEWS file to Markdown format
</ul>
</li>
</ul>
