I'm happy that Open Cascade SAS have released some bug fixes, but as a potential open source user it makes me a little nervous that the open source version doesn't also benefit from these fixes. This release tells me that OCC are distributing known buggy code for which they already have fixes. Seem like an odd thing to do.

This is the standard MO for OCC. They have done it this way ever since going "open source". They typically release 2 or 3 maintenance releases to their paying customers before releasing a new open source version with all the fixes.

I don't like it either, but I sort of understand their motivation. Service contracts are their only source of income.

I guess it would not be a big deal if it wasn't for the fact that they sit on any bug fixes also for a long time.
Rob Bachrach 2007/12/10 14:24
True...When this all started, they would release maintenance releases every few months and would release an public update a minimum of once a year. Since the last public release (6.2) was in March 2007, hopefully we will se another by the middle of next year.
