+## 20/Dec/2023
+
+* fixed the implementation of BIsAppInstalled(), it must lock the global mutex since it is thread-safe, otherwise it will cause starvation and the current thread wion't yield, which triggers some games
+
+* more accurate behavior for BIsAppInstalled(), reject app ID if it was in the DLC list and isUnlockAllDlc was false
+
+* basic implementation for RequestAppProofOfPurchaseKey() and RequestAllProofOfPurchaseKeys()
+
+* a simple implementation for GetEarliestPurchaseUnixTime()
+
+* more accurate implementation for BGetSessionClientResolution, set both x & y to 0
+
+* return false in Steam_Apps::BIsDlcInstalled() when the given app ID is the base game
+
+* check for invalid app ID uint32_max in different places
+
+* more accurate implementation for Steam_Client::BReleaseSteamPipe(), return true if the pipe was released successfully
+
+* lock the global mutex and the overlay mutex in different places just to be on the safe side, without it, some games suffer from thread starvation, might slow things down
+
+* added missing env var "SteamOverlayGameId" to steam_client and client_loader
+
+* added a startup timer + counter for reference, currently used to print timestamp in debug log
+
+* consistent debug log location, for games that change cwd multiple times while running
+
+* fixed error propagation in Windows build script, apparently set /a var+=another_var works only if another_var is a defined env var but NOT one of the "magic" builtins like errorlevel
