Preparations

1. don't apply the patch
2. in the Admin Console:
   1. login to the Admin Console
   2. go to the Logs & Reports → Changes Log section
   3. if there is warning message (above the grid) telling, that change log is disabled, then:
      1. click on the provided link to enable change log
      2. logout & login again
3. in the IDE:
   1. open core/admin_templates/languages/phrase_list.tpl file for editing
   2. change std_edit_item(...) to std_edit_temp_item(...)
   3. change std_precreate_item(...) to std_new_item(...)

Part 1

1. go to the Configuration → E-commerce → Shipping section
2. create a fully configured custom shipping type (with couple zones, couple brackets and several costs)
3. open just created shipping type for editing > change one zone's name & delete another zone > save changes
4. go to the Website & Content → Labels & Phrases section
5. add new phrase
6. open added phrase for editing > change something > save changes
7. delete some phrase
8. go to the Logs & Reports → Changes Log section
9. remeber conceptually how records look like

Part 2

1. apply the patch
2. repeat all the specs from Part 1, but instead of remembering (at last step) confirm, that after patch was applied the created change log records look conceptually the same (same actions produce same records (except for auto-increment id changes))
