• A filename or comment stored without the UTF-8 flag is decoded as UTF-8 when its bytes are valid UTF-8 and no filenameEncoding or commentEncoding option is set, instead of IBM Code Page 437. macOS Archive Utility, ditto, the macOS build of Info-ZIP zip and Java 6 write such names, which read back as mojibake until now while 7-Zip, libarchive and jar show them right. Pure ASCII names are unchanged, an explicit encoding option disables the detection, and a valid Info-ZIP Unicode Path extra field still wins
• The WebAssembly deflate runs in gzip mode and reads the CRC-32 of the entry from the trailer, as the native CompressionStream route already did, so the separate CRC-32 pass over the input on the JavaScript thread is gone for that codec: about 1 % of the time of a 20 MB text entry on Node.js. On the native-only build, the route wrapping gzip where deflate-raw is missing reuses the CRC-32 it computes for the trailer instead of running a second pass

• filenameValidation rejects, under "balanced", a ".." path component delimited by backslashes ("..\\file.txt", which a Windows host resolves as a parent directory) and a name starting with a single backslash (a root-relative or UNC path on Windows), and under "strict" a name holding a NUL character. A backslash is otherwise still a valid filename character
• A custom Reader whose readUint8Array returns a Node.js Buffer reads archives again. The end of central directory record was kept as Buffer#slice(...).buffer, a view on the whole scan window or on the Buffer pool, so its fields were read from the wrong bytes and every archive failed with ERR_SPLIT_ZIP_FILE or "File format is not recognized", since 2.8.30
• Retaining an Entry no longer retains the whole central directory (#682). rawFilename, rawExtraField and rawComment were views on the buffer holding the directory, as was the digital signature, so one entry kept alive pinned the metadata of every other one, 3.9 MB in the reporter's archive, and the .buffer of those fields exposed the reader's buffer, e.g. a Node.js Buffer pool. Each entry now owns one copy of its three fields
• terminateWorkers() runs in-process the requests queued while every worker slot was busy and resolves once they have finished. A request queued behind the call used to get a fresh worker after the call had resolved, so a ZipReader reading two entries at once with maxWorkers: 1 kept a worker alive past the call, and the WebAssembly builds reset the module under it. Writers were not affected: every add() waits for a slot before asking the pool

• checkAmbiguity documents that duplicate filenames are compared exactly, after normalizeFilename: two names differing by letter case or by Unicode normalization form are distinct entries, even though they collide on a case-insensitive or normalizing filesystem
• BENCHMARKS.md states what the rows of a fresh process include, the JIT warm-up of each library and, for the WebAssembly rows, the module instantiation of about 20 ms, and that no decompression row verifies the CRC-32: zip.js and jszip leave the check off by default and fflate has none on read. Turning it on in zip.js adds one pass over the output, about 15 ms per 20 MB

• The worker and WebAssembly modules embedded in the bundles are minified without property mangling before the main bundles mangle them, so the mangled-name guard no longer reports a spurious single-letter name on every regeneration. The bundles are unchanged within a few bytes

• New tests pin the unflagged UTF-8 names (zip.js's own useUnicodeFileNames: false output, a CP437 name, an explicit filenameEncoding winning and a real ditto archive), the ownership of the raw metadata against a pooled reader, the gzip trailer on the WebAssembly codec with the routes asserted through spies, the termination with a queued request, the clamped date warning under every timestamp option combination, the exact exported size when no deflate implementation is reachable, and the three worker options read as truthy values
