876 seemed to be bug free and was available as a browser based TWS. It is not available browser based or standalone any more. 875 down to 872.6 all incorrectly time stamp backfill data so if you rely on backfill 875 is next to useless. 877 screws up during execution of futures orders (twice last week for me including once on friday - bug reports forwarded). So its not reliable during trading. I have been asking since friday on the IB TWS board and being ignored (the usual on the TWS board I'm sad to say (there's a good guy on the api side but tws seems unrepresented). So I'm bringing it to the forum where someone from IB listens. Where is 876 .... its the best version of TWS currently available?????
