#14494 727b0a2 Thanks @florian-lefebvre! - Updates Markdown heading ID generation - (v6 upgrade guidance)
#15726 6f19ecc Thanks @ocavue! - Updates dependency shiki to v4
Check Shiki's upgrade guide.

#15277 cb99214 Thanks @ematipico! - Fixes an issue where the function createShikiHighlighter would always create a new Shiki highlighter instance. Now the function returns a cached version of the highlighter based on the Shiki options. This should improve the performance for sites that heavily rely on Shiki and code in their pages.
#15332 7c55f80 Thanks @matthewp! - Exposes the fileURL option in MarkdownProcessorRenderOptions, allowing callers to specify the file URL for resolving relative image paths.

#15187 bbb5811 Thanks @matthewp! - Update to Astro 6 beta
#15297 80f0225 Thanks @rururux! - Fixes a case where code blocks generated by prism would include the is:raw attribute in the final output
#15676 1fa4177 Thanks @rururux! - Fixes an issue where the use of the Code component would result in an unexpected error.
#15651 f94d3c5 Thanks @ocavue! - Reuses cached Shiki highlighter instances across languages.
