There was an high impact issue with 5.2.100 related this morning. Most of AR/AP type txns would fail with an error. this version fixes it.
The root cause of issue wasn't a software code bug but with how new versions of c9 are prepared and uploaded. This is the second time we have been caught out in last couple of years by this. Further changes have be put in place to make sure it doesn't happen again; as original tweaks made were not enough to catch this mornings issues.
Root cause : some sort of issue with incremental build for the main c9 software package resulting in corrupt compiled software : possibly a clash between in IDE incremental build process and command line build; switch to strict clean builds from now on.
