Fudge fudge fudge I did this.
I am really sorry this is something I vastly overlooked.
Next pizza & beer are on me.

Hi all,
I wanted to share a brief case study on the current dependency skew of
ImgLib2-algorithm-related components.
Last week, an innocent-looking commit was merged into imglib2-algorithm. It
then made its way into a patch release of imglib2-algorithm, and patch release
of pom-imagej. Unfortunately, even a trivial package move like this is actually
a breaking API change, and both the component and pom releases should have
incremented a major version to indicate this.
Further, pom-imagej now declares a set of components that are incompatible
with each other - as components downstream of imglib2-algorithm are not updated
to use the new packages. Thus if these libraries were consolidated (e.g. to
upload to Fiji), there would be hit by dependency skew.
For those interested, there are two possible solutions:
1) Track down all uses of the old packages, update them, cut releases, update
pom-imagej.
or
2) Add deprecated, trivial extensions of the moved classes back to the old
locations, which can then be removed at a later date.
Naturally, #2 is much simpler and thus looking more attractive right now. :)
Either way, developers should be aware of the current problems with pom-imagej
5.12.3 and 5.13.0 (the latter also points to an unreleased ij1-patcher, due to
incompatibilities with ImageJ 1.49p - so certainly don't use that one).
Our versioning practices are on the wiki:
http://imagej.net/Architecture#Versioning but please let us know if anything is
unclear or hard to find.
The burden of manually accounting for SemVer changes is hopefully one we will
soon be free from. For now, it's just something we have to consider whenever we
cut releases.
Best,
Mark
