Latest CTAN version incompatible with ShareLatex about latex

[hoodmane]

Okay so the problem is that ShareLatex has spectralsequences 1.0 which is incompatible with an update to xparse that happened since then. I will email their support folks and ask them to update the package.

Thanks for the swift reply. I didn't realise the ShareLatex caches the packages - I thought they grabbed them directly from CTAN when they were updated. Thanks for getting in contact with them.

The response is that it won't be fixed for a while:

Hi,

Thank you for getting in touch about this, sorry that the most recent package is not installed on the servers. ShareLaTeX tracks TeXLive Stable, updating all the packages only about once a year to prevent conflicts, so unfortunately we can't update individual packages separately. However, the newer version can be used in any project by uploading the .sty file to the root directory. Hope this helps.

Kind regards,
Harriet
