Release 7.4.1

Bug Fixes and Improvements

• #3441: Wrap AppKit/Cocoa display-name calls in an autorelease pool, extract ObjCFunctions FFM bindings, and use ExceptionUtil for consistent error handling - @dbwiddis.
• #3442: Convert static memoized suppliers to instance fields, allowing cached data to be reclaimed when users create new SystemInfo instances - @dbwiddis.
• #3443: Share memoized iostat supplier across disk instances; cache pluggable hardware lists (displays, USB, sound cards, graphics cards) in the HAL with a 3-second TTL - @dbwiddis.
• #3444: Consolidate try/catch-log-return-default patterns to use ExceptionUtil - @dbwiddis.
• #3459: Deduplicate the Windows CentralProcessor frequency queries into the shared base, and fix the JNA per-processor current-frequency numbering, which mis-assigned frequencies to logical processors on multi-processor-group/NUMA systems - @dbwiddis.
• #3473: Fix several macOS bugs: correct Intel Mac sensor temperatures that were under-reported by the SP78 fractional byte, decode process working directories and login sessions as UTF-8, and add missing null/bounds guards on native results - @dbwiddis.
• #3478: Fix several Windows bugs: stop reporting a UPS/non-system battery as the system battery, restore the WMI fallback (and avoid an NPE) when a PDH wildcard collection fails, drop phantom file stores for volumes that can't be queried, keep enumerating sound cards past an incomplete registry key, retain sessions without a client address, and include processors in NUMA nodes spanning more than 64 logical processors - @dbwiddis.
• #3479: Fix several Windows bugs: return all configured DNS servers instead of an empty list when more than one is present, keep querying the OpenHardwareMonitor/LibreHardwareMonitor namespaces after an initial failure so late-started sensors still appear, and classify CD-ROM drives as non-local - @dbwiddis.
• #3480: Align remaining JNA/FFM inconsistencies: report disk type (Removable/SSD/HDD/Unknown) on the native-free Linux backend, allocate a large enough buffer for long UTF-16 device names in the Windows JNA DeviceTree, fix WMI query when COM is already initialized in another apartment, returning zeroed TCP/UDP stats instead of null on a query failure, detecting x86 via GetNativeSystemInfo (correct under WOW64), and retrying the initial PDH_NO_DATA performance-counter sample - @dbwiddis.
• #3481: Share one registry-value parser between the JNA and FFM Windows installed-applications backends, so an application is resolved identically regardless of backend even when a value is stored as REG_DWORD or REG_BINARY rather than a string - @dbwiddis.
• #3482: Fix macOS getThreadCount() on the default JNA backend, which under-reported the thread count (a proc_listpids buffer size passed as an element count, and stale reused-buffer data counted for processes proc_pidinfo could not fill), and release the CoreFoundation device dictionary and lookup keys leaked per disk enumeration in the JNA disk-type detection - @dbwiddis.
• #3483: Fix several Windows backend issues: guard against a hard crash when enumerating a network session with a null client name, allocate the AMD ADL callback buffer from the C heap so the driver's free() is valid, close leaked system event-log handles, and read REG_QWORD/REG_BINARY registry values in the FFM backend so graphics-card VRAM is reported consistently with the JNA backend - @dbwiddis.
• #3484: Fix several parsing and consistency issues: return empty instead of throwing from ParseUtil.getStringBetween on a single unmatched delimiter, throw the documented IllegalArgumentException (not ArrayIndexOutOfBoundsException) for mismatched tick arrays, correct an off-by-one bounds guard in Solaris Prtvtoc, decode FreeBSD/Solaris utmpx session strings as UTF-8, and read native utmpx for Solaris sessions in the FFM backend to match the JNA backend - @dbwiddis.

New Features

• #3415: Add Display.getDisplayInfo() and a new DisplayInfo interface (exposing decoded attributes including isEdidSynthetic()), plus EDID-encoding methods in EdidUtil, allowing display attributes to be exposed without a raw EDID - @dbwiddis.
• #3436: Detect the Apple Silicon built-in Retina display via IOMobileFramebuffer and synthesize a DisplayInfo from CoreGraphics and NSScreen properties (resolution, physical size, serial, model name) - @dbwiddis.

Bug Fixes and Improvements

• #3424: Fix WrongMethodTypeException when freeing BSTR strings on the Windows FFM WMI path, caused by a void invokeExact in an expression lambda inferring an Object return - @dbwiddis.
• #3425: Fix the Windows perf-counter process and thread maps occasionally mis-keying a real process/thread under ID 0, when PDH reports its "ID Process"/"ID Thread" sentinel for one that is starting or exiting - @dbwiddis.
• #3432: Replace Logger#atLevel/setCause/isEnabledForLevel usage in ExceptionUtil, PerfDataUtil, and ForeignFunctions with level-switches to the classic SLF4J methods, so oshi no longer requires slf4j-api 2.x at runtime - @wolfs.
• #3431: Declare the optional jlibrehardwaremonitor OSGi package imports as optional, so oshi-common resolves in OSGi environments that do not provide it - @MrEasy.
• #3433: Restore optional JNA native access for NetBSD, falling back to the command-line implementation when the JNA native library is not installed - @dbwiddis.
• #3437: Add ParseUtil.decodeIntOrDefault/decodeLongOrDefault and forbid direct use of Integer.decode, Long.decode, parseUnsignedInt, and parseUnsignedLong - @dbwiddis.
• #3438: Deprecate Display.getEdid() in favor of Display.getDisplayInfo().getEdid(), consolidating display data access under DisplayInfo - @dbwiddis.
