Key Changes:

• Modified the primary description text for pathway network plots within all tissue-level graphical clustering report pages due to the omission of embedded interactive pathway network plots. A reusable component has been used to replace all embedded description text.
• Changed the Data Hub tutorial video link to the version on YouTube instead of on Google Drive on the Homepage and Tutorials page.
• Modified the appearance of PRE-CAWG and DAWG-PAC tabs on the MAWG resources page so that they are visible.
• Removed the text “(deadline for revisions: 4/1/2024)” from the DAWG-PAC “Analysis Report (deadline for revisions: 4/1/2024)” bullet point on the MAWG resources page.
