Language	Command
npm	`npm outdated`
Python (pip)	`pip list --outdated`
Python (poetry)	`poetry show --outdated`
Go	`go list -m -u all`

Language	Update Single	Update All
npm	`npm install pkg@version`	`npm update`
pip	`pip install pkg==version`	`pip install -U -r requirements.txt`
Go	`go get pkg@version`	`go get -u ./...`

Risk Level	Criteria	Approach
Low	Patch update, no breaking changes	Direct update
Medium	Minor version, some deprecations	Plan + test
High	Major version, breaking changes	Detailed plan + staging
Critical	Stack migration, data schema changes	Phased rollout + rollback ready

Stack	From -> To	Key Changes
React	18 -> 19	React Compiler, Actions, use() hook
Next.js	14 -> 15	Async Request APIs, React 19
Node.js	20 -> 22	WebSocket client, glob/require sync

Stack	From -> To	Key Changes
Python	3.11 -> 3.12	Type param syntax, f-string changes
Django	4.x -> 5.x	Async support, facet filters
FastAPI	0.100+	Pydantic v2 required

Stack	From -> To	Key Changes
Go	1.21 -> 1.22	Range over integers, enhanced routing
Go	1.22 -> 1.23	Iterators, timer changes

DON'T	DO
Update everything at once	Update incrementally
Skip reading changelogs	Read migration guides thoroughly
Migrate in production	Test in staging first
Forget rollback plan	Always have a way back
Rush the process	Take time, verify each step
Assume it works	Run full test suite
