Match history access and sharing-code rules
The August 31, 2023 Limited Test update granted third-party websites access to match history for Competitive, Wingman and Premier matches. This enabled external services to request history across those three CS2 modes; the patch does not describe the storage period for every match or the design of any individual website.
The same update changed the `GetNextMatchSharingCode` API requirement: a website must supply a match-sharing code no more than one month old to obtain the next code. This is a freshness limit in the code-exchange sequence, not a general one-month limit on all match-history access. The rule is recorded for the Limited Test build and may be superseded by later API revisions.
End-of-match statistics (July 21, 2023)
The July 21, 2023 Limited Test update fixed a case where some match statistics were reported incorrectly at the end of a game. The patch does not identify the affected statistics or say that stored match history was rewritten. This is a dated reporting correction, separate from matchmaking results and match-sharing code eligibility.
