A change log consists of sections pulled directly from the issue management system that is automatically processed into a spreadsheet. The spreadsheet can be sorted/viewed by many criteria, such as date of the fix, component affected, severity and more.
There usually are a fair number of entries (sometimes more than 1000), because each update published contains all the accumulated changes made since some base release in the past and the change log has entries for everything from major bugs to minor improvements to documentation changes and spelling errors fixed.
The main reasons for pulling the change logs was the fear of putting the software in a bad light and risking ridicule, especially from the competition.
Although I can follow these arguments up to a point, I've personally always been more comfortable with software that had explicit and detailed change logs: Errors and bugs happen, whether they are communicated or not, and I'd rather know what was changed than blindly install some patch without knowing if it's relevant for the issues I'm trying to solve.
What is your opinion? Should change logs / errors / bugs be communicated openly?
How is this handled in the companies you work for?
Can you provide publicly available references on the pros and cons of open and honest communication of changes and bug fixes, especially in commercial environments?"
A new paper by UW astronomer Tyler Robinson and planetary scientist David Catling, published online Dec. 8 in the journal Nature Geoscience, uses basic physics to show why this happens, and suggests that tropopauses are probably common to billions of thick-atmosphere planets and moons throughout the galaxy. “The explanation lies in the physics of infrared radiation,” said Robinson. Atmospheric gases gain energy by absorbing infrared light from the sunlit surface of a rocky planet or from the deeper parts of the atmosphere of a planet like Jupiter, which has no surface. The research shows that at high altitudes atmospheres become transparent to thermal radiation due to the low pressure. The findings could be used to extrapolate temperature and pressure conditions on the surface of planets and work out whether the worlds are potentially habitable — the key being whether pressure and temperature conditions allow liquid water on the surface of a rocky planet."
