Build 312, released 2026/06/04

• Deprecate pythoncom.frozen and resolve build deprecation warnings (mhammond#2593, [@​Avasam][Avasam]) pythoncom.frozen used to expose Py_FrozenFlag from the C API. Py_FrozenFlag is deprecated since Python 3.12.
• Added Python 3.15 support (mhammond#2729, mhammond#2732, [@​Avasam][Avasam])
• Removed special-casing for .pyo files which haven't been a thing since Python 3.5 (mhammond#2754, [@​Avasam][Avasam])
• Fixed axdebug build on Python 3.11+ using CPython's new opaque frame APIs, fixed 64-bit overflow in sourceContext and stack addresses, fixed incorrect step-over and step-out behavior, and fixed ListEnumeratorGateway.Next() returning lazy map iterator incompatible with C++ COM gateways that require a sequence (mhammond#2723, mhammond#2724, mhammond#2725, [@​wxinix-2022][wxinix-2022])
• Removed more leftover obsolete UNICODE constants since dropping Python 2 support in win32ui, win32gui and win32clipboard (mhammond#2717, [@​Avasam][Avasam])
• Implement COM Records as [out] method parameters (mhammond#2708, [@​geppi][geppi], [@​the-snork][the-snork])
• Implement multidimensional SAFEARRAY(COM Record) and SAFEARRAY(double) (mhammond#2655, [@​geppi][geppi])
• Added many missing license and copyright notice files (mhammond#2590, [@​Avasam][Avasam])
• Fixed missing version stamp on built .dll and .exe files (mhammond#2647, [@​Avasam][Avasam])
• Bugfix for COM Record instance creation (mhammond#2641, [@​geppi][geppi])
• Fix regression introduced by mhammond#2506 (mhammond#2640, [@​geppi][geppi])
• Fixed LoadPerfCounterTextStrings and UnloadPerfCounterTextStrings's bQuiet param being unused and hardcoded to True (mhammond#2711, [@​Avasam][Avasam])
• Removed considerations for unsupported Windows Versions (95/98/ME/2000/2k/Vista, most of XP) (mhammond#2711, mhammond#2667, mhammond#2400, mhammond#2747, mhammond#2752 [@​Avasam][Avasam])
  • Updated a lot of dynamic function loading at runtime to instead use static build linking
  • Updated a lot of documentation
  • This removes the following constants:
    • win32con.FILE_ATTRIBUTE_ATOMIC_WRITE
    • win32con.FILE_ATTRIBUTE_XACTION_WRITE
• Removed considerations for MFC < 9 (VS 2008) (mhammond#2669, mhammond#2716, [@​Avasam][Avasam])
  • This removes the unusable PyCSliderCtrl.VerifyPos method
• win32cred.{CredWrite, CredUIPromptForCredentials}, win32net.NetUserEnum, win32profile.{LoadUserProfile,UnloadUserProfile,CreateEnvironmentBlock}, win32security.{LogonUser, LookupAccountName, SetNamedSecurityInfo, GetNamedSecurityInfo, LsaAddAccountRights, ConvertSidToStringSid} all now release the GIL before making the call (#2732)
• Fix memory leak in PyCom_VariantFromPyObject (#2688)
• Dropped support for Python 3.8 (mhammond#2413, [@​Avasam][Avasam])
  • Note that whilst pywin32 hasn't explicitly dropped support for Windows 7 / 8 / Server 2008, Python 3.8 was the last official CPython version to support those versions (Python 3.9 installer requires at least Windows 8.1 / Server 2012).

Build 311, released 2025/07/14

• Fix use-after-free in CertDeleteCertificateFromStore (mhammond#2637)
• Better support for COM identifiers with non-ascii characters (mhammond#2632)
• pywin32's own warnings will now refer to the caller, rather than to the internal source of warning itself (mhammond#2594, [@​Avasam][Avasam])
• Fixed a regression that broke special __dunder__ methods with CoClass. (mhammond#1870, mhammond#2493, [@​Avasam][Avasam], [@​geppi][geppi])
• Fixed TypeError: cannot unpack non-iterable NoneType object when registering an axscript client ScriptItem (mhammond#2513, [@​Avasam][Avasam])
• Fixed a memory leak when SafeArrays are used as out parameters ([@​the-snork][the-snork])
• Fixed dispatch handling for properties ([@​the-snork][the-snork])
• Resolved a handful of deprecation warnings (mhammond#2567, mhammond#2576, [@​Avasam][Avasam])
• The following classes now produce a valid eval string representation when calling repr: (mhammond#2573, [@​Avasam][Avasam])
  • pywin.tools.browser.HLIPythonObject
  • win32com.server.exception.COMException
  • win32comext.axscript.client.error.AXScriptException
  • win32comext.axscript.client.pyscript.NamedScriptAttribute
