19c RU Bugs Fixes

An year ago i've wrote the post "Time to upgrade to 19c"

Now it is the time to refresh the picture.

After the time new release have been issued, the question arises - is it time to move to the new release?
Is it good enough to work in production by now?
Usually users wait a while for a release to be "good enough" and for bugs to be fixed.

What is the criterion we may use to define whether a release is good and fine tuned enough?

As one of the criteria, we can take the number of bugs that are fixed in the each quarterly patch.
The logic here is: in the beginning, after a new release, a few people immediately start using it.
That's why the number of patches in the quarterly patch list is pretty small.
Gradually, the activity of users is growing, and then the number of identified problems/bugs is growing too. Therefore, the number of fixes in the patchset also increases.
After the time the software reaches a state where all the major bugs are fixed and the number of patches in the patchset decreases. Such an inflection point can be considered a stage of maturity of the software product.
