Pricing moves without announcement and it is the field most likely to be wrong on any given day, so treat every figure here as the starting point for a check rather than the end of one. Each price carries the vendor page it was read from, which is the fastest way to confirm it yourself.
Capability claims move far more slowly. Whether a tool runs offline, exposes an API or supports SSO is usually true for years at a time, and those are the claims the research prioritises for that reason.
A correction does not require you to be polite or detailed. Name the page and the thing that is wrong, and it gets checked against the source rather than against the complaint. If the source disagrees with us, we change; if it disagrees with you, we will say so and show you why.
