As a heavy user, an occasional contributor, and the person who recently mined PyPi for all the historical SqlAlchemy data to generate the new release history matrix...
I don't think you have anything to really worry about for long term use. The majority of updates over the past 7 years that have been released deal with: • new functionality or improved performance • very specific bug fixes (ie, edge cases or dialect/driver issues) Although versions may hit their EOL within 2 years: - there is rarely any reason to upgrade old projects - mike is really nice, and often backports certain fixes to earlier branches that are technically out-of-support I have legacy projects in production that are using .5,x .6.x and .7x. - virtualenv makes pegging sqlalchemy versions a non-issue In terms of the time needed to upgrade -- I once had to upgrade a .4.x project to the .9.x series. it took 45 minutes to change some code, integrate find/replace on backwards incompatbiliites, and address test failures. Those 45 minutes correlated to hours saved by new features. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
