MINOR
No substantive policy changes were made. The diff reflects a conversion of ACR 132 (Rare Disease Day) from its formal authenticated chaptered document format to a web page display format on the California Legislature website. All legislative content, including the WHEREAS clauses and resolutions, is identical between the two versions.
TECHNICAL
The bill text was reformatted from an official authenticated legislative document (with headers like 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL' and page numbers) into a web page layout that includes navigation menus, search boxes, version history links, and other website UI elements. The actual resolution text designating February 28, 2026 as Rare Disease Day is unchanged.
