| 3 | This is a list of the most important changes between 2.x versions. It is by |
|---|
| 4 | no means complete, listing only user-visible changes which are interesting. |
|---|
| 5 | The ultimate way to know what has changed is to run diff, or even neater, |
|---|
| 6 | ask CVS about it: |
|---|
| 7 | |
|---|
| 8 | * Checkout the archive (see doc/cvs for how you can do this) |
|---|
| 9 | * Determine which tags are valid, by running this command from the |
|---|
| 10 | project root directory: |
|---|
| 11 | cvs status -v -l Makefile |
|---|
| 12 | Valid tags are usually like form V2-1-0 for version 2.1.0 |
|---|
| 13 | * Ask cvs for the difference between two versions: |
|---|
| 14 | cvs diff -r TAG1 -r TAG2 DIFF-OPTIONS |
|---|
| 15 | for example: |
|---|
| 16 | cvs diff -r V2-0-0 -r V2-0-1 -u |
