This release is now available on Maven Central, based on Bouncy Castle r1rv58. See https://www.bouncycastle.org/releasenotes.html for more details about the updates in this release.
Special thanks to @btcontract who again kindly made a donation towards the always non-trivial process of cutting this release. If you represent a bank or other financial institution that uses Spongy Castle in it's apps (and there are a lot of those!) please consider following this example making a contribution towards the maintenance & release of this library!
As new elements required string substitution in this release, I had to make modification to the bash BC->SC conversion scripts (which live on a separate branch under https://github.com/rtyley/spongycastle/commits/spongy-scripts). After a half-hour or so trying to correctly escape doublequotes in bash scripts invoking ssed expressions, I table-flipped and rewrote the conversion in Scala instead - this new code is much faster and makes use of libraries from my BFG Repo-Cleaner tool, which is normally used to rewrite Git history, but here instead it's just used to quickly create a new commit with a rewritten file tree.
