While in general the stable version is indeed more stable (as in "less buggy", at the expense of fewer new features) compared to the latest version, in some specific cases the stable version may actually be more buggy. For example, the current stable version (10.30) has a known issue for users of old API engines, causing a Fatal 505 error after order placement. This was reportedly fixed in 10.31 onward, and the latest version (10.34) does not exhibit this problem. In other words, users of old API engines CANNOT use the stable version and MUST use the latest version instead, especially since using a pre-10.30 version is no longer possible as of yesterday. Unfortunately, it takes a bit of digging in the IBKR website to find the latest version, since the stable version is offered by default. I have no clue as to why IBKR continues to use the 10.30 branch as the promoted "stable" version rather than 10.31 or newer, although they know about the 505 problem for at least the past 6 months.
