Changes	Every program file and library the installer puts on the machine is now code-signed, including the Cygwin libraries Squid runs on. On Windows 11 with Smart App Control turned on, 1.0.0 and 1.0.1 could not start the proxy, because Smart App Control refuses unsigned libraries. Saving on the Configuration page while the proxy is running now offers to restart it, so the new settings take effect straight away. Before, the proxy kept its old configuration until it next restarted. When Windows refuses to start Squid (for example, Smart App Control, another application-control policy or a missing library), event 101 now says so in plain words and where to look, instead of only an error code. Same Squid 7.8 as 1.0.1.

Changes	Bundles Squid 7.8, with our fix to its Windows sign-on helpers: Negotiate sign-on no longer crashes the proxy, and NTLM logs user names as DOMAIN\user (it logged them without the backslash, or as a quote mark for a browser on the proxy machine). New setting: Require Windows domain sign-on (Active Directory), on the Configuration page and in the Setup Wizard. The access rules still decide which computers may connect; sign-on decides who. Optionally, computers outside the domain can be asked for a user name and password. The data folder (C:\ProgramData\SquidProxyPro: cache, logs, settings, backups) is now open to SYSTEM and Administrators only, including files written before the upgrade. 1.0.0 let any local user read and change it. Event Viewer now shows the text of every Squid Proxy Professional event, instead of an unrelated Windows message. The service picks up DNS server changes while it runs (after startup, on a VPN, or on another network) and logs event 120, unless squid.conf sets dns_nameservers. If Squid stops unexpectedly after it has started serving, the service restarts it (at most twice a day); before, a stop within the first minute left the proxy off. A 64-bit installer, and the uninstaller is now signed too. "License" is spelled the US way throughout; the license agreement is version 1.1 for that reason only.
