Updated mediawiki/extensions Project: mediawiki/extensions/CentralNotice 90f1b992e94cf2ae841026c4c5545d608f18bafd

Migrate to a terser cookie name and format

• Rename cookie from 'centralnotice_buckets_by_campaign' to 'CN'.
• Store start as offset from UNIX time 1400000000 (March 2014).
• Store end as offset from start.
• Instead of JSON, use this format: 'NAME!START!END!VALUE'. Separate campaigns with '*'.

Before:

centralnotice_buckets_by_campaign=%257B%2522WikiConference_USA%2522
%253A%257B%2522val%2522%253A0%252C%2522start%2522%253A1439942400%25
2C%2522end%2522%253A1443672000%257D%257D

After:

CN=WikiConference_USA!39942400!3729600
