 - Add commit network as a new type of network. It uses commits as vertices and connects them either via cochange or commit interactions. This includes adding new config parameters and the function `add.vertex.attribute.commit.network` for adding vertex attributes to a commit network (PR #263, ab73271781e8e9a0715f784936df4b371d64c338, ab73271781e8e9a0715f784936df4b371d64c338, cd9a930fcb54ff465c2a5a7c43cfe82ac15c134d)
 - Add `remove.duplicate.edges` function that takes a network as input and conflates identical edges (PR #268, d9a4be417b340812b744f59398ba6460ba527e1c, 0c2f47c4fea6f5f2f582c0259f8cf23af985058a, c6e90dd9cb462232563f753f414da14a24b392a3)
 - Add `cumulative` as an argument to `construct.ranges` which enables the creation of cumulative ranges from given revisions (PR #268, a135f6bb6f83ccb03ae27c735c2700fccc1ee0c8, 8ec207f1e306ef6a641fb0205a9982fa89c7e0d9)
+- Add function `get.last.activity.data` to compute developers' last activities in a project, as well as function `add.vertex.attribute.author.last.activity` to add a developer's date of last activity as vertex attribute to a network, as well as helper functions `get.aggregated.activity.data` and `add.vertex.attribute.author.aggregated.activity` to allow for other activity aggregations than first and last activity (PR #275, 88302e9f4dd738f8c17357e624f7179cb39d145c, 35753b6c87463d1eb03f55cdd85e21af58558d55)
