2.0.0

Released 20-Apr-2023

  • This release introduces major changes to how Geneagrapher works internally. Previously, the logic to retrieve information from the Mathematics Genealogy Project and build graphs was in Geneagrapher. As of this release, that work is done by a service that Geneagrapher makes requests to. That service is built using geneagrapher-core.
  • Graph building is now more flexible. Previously, traversal from the graph's starting nodes was either all in the advisor direction or in the descendant direction. Traversal directions are now specified on a per-node basis. This has led to some syntax changes in the tool's usage, so commands that worked in Geneagrapher 1.0.0 will not work in 2.0.0.
  • This is the first version of Geneagrapher targeted only for Python 3.
  • The test system was completely overhauled and modernized.
  • The source code now uses type hints.
  • A CI workflow has been added to automatically run code formatting, linter, and type hint checks, as well as the test suite.

1.0.0

Released 07-Oct-2018

  • Redesigned data-grabbing interface to allow for the introduction of new data grabbers.
  • Added a new data grabber that builds a local cache of records. This allows subsequent geneagrapher calls to obtain cached records and avoiding a request over the network.
  • Added local test data, allowing for many tests that were previously making network requests to simply load local data. This speeds up running the test suite substantially.
  • Substantial refactoring and internal changes, including:
    • Better code coverage by the tests.
    • Updated packaging to more modern standards.
    • Improved test documentation and naming.
    • Internal graph structure now only stores the genealogy graph. Previously, the graph structure retained all edges from the Math Genealogy Project information.
    • Data is now extracted from Math Genealogy Project web pages using BeautifulSoup. This means that the Geneagrapher now has an external dependency, but I believe the advantages for testing and code readability, for this case, outweigh the disadvantage of taking a dependency.

0.2.1-r2

Released 11-Aug-2011

  • A test in Geneagrapher 0.2.1-r1 was broken by new information addedto the Mathematics Genealogy Project. This release fixes the test, but does not change the functionality from version 0.2.1-r1.

0.2.1-r1

Released 03-Nov-2010

  • A few tests in Geneagrapher 0.2.1 have become broken since that version was released. This release fixes those tests, but does not change the functionality from version 0.2.1.

0.2.1

Released 01-Sep-2009

  • Multiple advisors are now captured correctly. While this problem was manifesting itself, ancestor trees were coming out as a branch-free tree.
  • Added a test for the multiple advisor case, which enables quicker recognition of similar problems.
  • Updated a few tests that had become broken due to updates in the Math Genealogy Project’s database.

0.2-r1

Released 07-Oct-2008

  • This Geneagrapher release slightly changes an installation-related file to enable installation on machines running Python 2.6 that have not yet installed Python setuptools.

0.2.0

Released 06-Oct-2008

Here are the most significant changes, from the perspective of the user:

  • Descendant trees. Now trees can be built placing a starting node at the top and graphing all of its descendants. A couple points on this:
    • These sorts of graphs tend to have a lot of “fan out” because some people have a lot of students.
    • Be careful. Do not inadvertently (or intentionally!) run a job that requests the data for thousands of nodes.
  • Better character handling. I believe all characters are now displayed correctly, as long as the generated dot file is processed by Graphviz a certain way (see the Geneagrapher 0.2 Usage Guide).
  • No limit on the number of starting nodes.
  • This is a client application, meaning the user installs it somewhere and runs it there. Furthermore, this package only generates the input file to Graphviz, so that also needs to be installed. This is probably more of a hassle than most Geneagrapher users want to go through (not all, though), but this is just the first step.

Additionally, behind-the-scenes changes happened:

  • Large portions of the code were rewritten.
  • Added a test suite to make it more maintainable. In particular, this should allow quicker diagnosis and modifications when the Mathematics Genealogy Project pages have changed.
