Spongy Castle v1.56.0.0 (from BC v1.56)
This release is now available on Maven Central, based on Bouncy Castle r1rv56. See https://www.bouncycastle.org/releasenotes.html for more details about the updates in this release.
Note that due to the upstream changes in Bouncy Castle commit 692173 the following artifacts have been renamed:
pkix->bcpkix-jdk15onpg->bcpg-jdk15on
...the core and prov packages remain with the same name.
One change I had to make with this release was my choice of CI server - I've always tried to use a public CI server to make it easier to reproduce my results, but unfortunately, while it's always been eventually possible to fix-up the test suite so that it passes on my local dev machine, it's been increasingly hard to get the build to pass on Travis CI, and I just didn't have time to resolve those issues this time. As such, I've switched to CodeShip for this project, which unfortunately means that the build-results page is no longer public - tho' at least the status information is available in the GitHub Status API.
Many thanks to the users who gave feedback on issue #34 ("Is Spongy Castle obsolete?") - it looks like the answer is currently not quite - and especially to @btcontract who kindly made a donation towards the always non-trivial process of cutting this release.
