Where can I read about the features/improvements/fixes in 6.7 before updating? Currently, wealth-lab.com and the wiki still reference version 6.6.

One can not read about it before updating - only after (in the User Guide > New and Noteworthy > What's New). This is a maintenance release that contains the following bug fixes:

Index-Lab

·(146423) The "Invalid indicator settings" bug after creating an aggregate indicator (introduced in "Pro" Version 6.6) is resolved.

Strategy Builder Rules

·(44245) The condition for "Stochastic %D crosses above overbought level" had reversed the "StochD period" and "StochD smoothing" parameters in the wizard and in the generated code output. We recommend retesting and/or recreating Strategies that use this rule.

Backtesting

·(13945) Benchmark Buy & Hold May Start on the Wrong Bar

Markets.xml

·(146427)
a) Fixed the date for the November 2013 Thanksgiving special hours session.
b) Added observed Friday holiday for 7/3/2009.
c) Superfluous Saturday and Sunday dates for holidays were removed.
d) Added 2015 dates for special hour sessions.

Indicator Drag & Drop

·(17617) Dropping an indicator on another existing indicator and then "pushing" the result to code will no longer cause an exception.

Notes:
1. WL Pro customers can't read about it before upgrading. When the WL Dev build is ready, we update the Home page with this information.

2. In addition to the changes above (which are the ones that also apply to WL Dev), the main emphasis of the WL Pro release is the integration of the Equity Summary Score provider, which allows you to download and backtest with ESS histories.

Thank you for the summary of changes. It would be nice to see that list before I have to click the download/install button, so I may estimate the urgency or potential disruption before installing the new version.

Same question, new version..

What is new/changed in Wealth-Lab Pro version 6.8? Thank you. The wiki and website still refer to 6.6.

As there hasn't been Wealth-Lab Developer 6.7 (and no 6.8 yet), the site, Wiki and the WL Home Page tool haven't been updated to reflect the changes.

6.8 is worth to install (along with .NET 4.5 Framework which is now required) to be able to do limited margin trading in IRA accounts and specify dividend source for portfolio simulations (which should be beneficial to Developer customers). Moreover, it contains a number of long-awaited bug fixes: "Stuck Submitted" orders at Fidelity, crashes on changing regional settings and Email Alert failures, graceful handling of invalid Buy&Hold symbol, minor improvement of Combo Strategies performance, some Strategy Monitor and Strategy Builder bugs, and more.

Wealth-Lab Pro 6.8 Home Page has some information, and it points to the User Guide for finer details.

I expect to have Wealth-Lab Developer 6.8 installation ready within the next two weeks (maybe next week).

Thank you Eugene and thank you Cone, for this information.
