<div dir="ltr">I made a new release 2.10.7 of CoinUtils with the suggested fix in it and a release 1.4.1 of Bcp incorporating the CoinUtils release. The fix seemed to be correct and did not break any tests. However, as I am not using Bcp regularly, it would be great if anyone else who is out there and using Bcp could test and report. <div><br></div><div>Thanks!</div><div><br></div><div>Ted</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Mar 21, 2015 at 3:38 PM, Ted Ralphs <span dir="ltr"><<a href="mailto:tkralphs@lehigh.edu" target="_blank">tkralphs@lehigh.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>I will try to take a look at this, but just so you know, BCP is not very carefully maintained anymore.
