4 * perf: replace regular expression with substring
9 * Use SHA1 instead of MD5 for ETag hashing
10 - Improves performance for larger entities
11 - Works with FIPS 140-2 OpenSSL configuration
16 * Always include entity length in ETags for hash length extensions
17 * Generate non-Stats ETags using MD5 only (no longer CRC32)
18 * Improve stat performance by removing hashing
19 * Remove base64 padding in ETags to shorten
20 * Use MD5 instead of MD4 in weak ETags over 1KB
25 * Improve support for JXcore
26 * Remove requirement of `atime` in the stats object
27 * Support "fake" stats objects in environments without `fs`
38 * Improve string performance
39 * Slightly improve speed for weak ETags over 1KB
44 * Support "fake" stats objects
50 * Use the (new and improved) `crc` for crc32
55 * Default strings to strong ETags
56 * Improve speed for weak ETags over 1KB
61 * Use the (much faster) `buffer-crc32` for crc32
66 * Add support for file stat objects
71 * Add fast-path for empty entity
72 * Add weak ETag generation
73 * Shrink size of generated ETags
78 * Fix behavior of string containing Unicode
