# Release Notes v0.11.6 : ZBDD as a Product Container | ||
|
||
Analysis and post-analysis facilities work directly with a ZBDD-based product container | ||
without paying memory or speed overhead of converting ZBDD into other data structures. | ||
|
||
|
||
## Major Changes | ||
|
||
- ZBDD as a fault tree analysis result (product/cut-set) container (#159) | ||
|
||
* Qualitative analysis speedup from 10% to 5x (the more the products, the bigger the effect) | ||
* Memory consumption decreases by 1.5 - 4x (noticeable only for million or more products) | ||
* Iteration over products is ~2x slower (graph walk vs. sequential array of products) | ||
* Quantitative analysis with approximations (rare-event, MCUB) is 2 - 10x slower | ||
(the fewer the products, the worse the effect) | ||
|
||
|
||
## Minor Changes | ||
|
||
- Package for Windows (#157) | ||
- Package for macOS (#158) | ||
- HTTPS support for the website | ||
|
||
|
||
## Bug Fixes | ||
|
||
- Incorrect formula for Histogram distribution expected value (#149) | ||
- Histogram distribution XML schema missing lower-boundary expression (#148) | ||
|
||
|
||
