Revision history for base64

0.4.2.2

• Add NFData, Exception, and Generic instances for Base64Error + @since annotations for new instances. (#28)
• Doc improvements and add -XTrustworty and -XSafe annotations where needed. (#27)
• Improve URL canonicity validation and correctness checking (now supports correct checking for unpadded Base64url) (#26)
• Fixed perf regressions in decode
• Test coverage is at 98%

0.4.2.1

• Security fix: reject non-canonical base64 encoded values - (#25)

• Perf improvements

0.4.2

• Added support for Data.ByteString.Short, Data.ByteString.Lazy, Data.Text.Short, and Data.Text.Lazy. (#17)
• Optimize decode algorithm (now beats base64-bytestring in every category!) - (#13)
• Use decodeLatin1 when decoding to text, so that functions are total - (#13)
• Added decodeWith* variants and a Base64Error type to handle decoding errors when decoding base64 values - (#13)
• Improved error reporting: all offsets are now precisely accurate. - (#13)
• Validations added to head, rejecting invalid corner cases (such as bytestrings of length l == 1 mod 4, which are never correct) - (#16)
• Added decodeBase64Padded for symmetry - (#13)

0.4.1 – 2020-02-04

• Optimize loops for 32-bit and 64-bit architectures
• Restructure project to be more amenable to swapping head/tail/loops
• Fix module header alignment

0.4.0 – 2020-01-26

• With this major version release, we remove the redundant encodeBase64Unpadded and decodeBase64Unpadded functions from Base64.hs. This is for two reasons:

  1. There is no reason for them to exist, since all std base64 is expected to be padded (in contrast to base64url)
  2. it was literally redundant with decodeBase64.

• Use a specialized Bool type to give better visual cues regarding which functions add padding

0.3.1.1 – 2020-01-15

• Make sure benchmark code builds

0.3.1.0 – 2020-01-08

• Bug fix for isBase64 and isBase64Url - wrong alphabet was used
• Added isValidBase64 and isValidBase64Url for alphabet conformity. The isBase64* functions now tell if it’s correct base64 now in the sense that it’s decodable and valid.
• Dropped Cabal version to 2.0 for backcompat with Stack
• Better documentation

0.3.0.0 – 2020-01-07

• After a discussion with lexilambda, we’re making ‘encodeBase64’ be ByteString -> Text by default, offering ByteString -> ByteString as a secondary format.
• Add decodeBase64Lenient to the API for phadej
• Fix unpadded decoding bug where garbage was appended to the end of garbage inputs. A cleaner way to do this is to simply encode as Base64 with padding and then strip padding chars until I come up with a workflow specific to unpadded inputs (I used to have this, so I’ll have to dig it up)
• Added isBase64 and isBase64Url to the API
• Performance is stable

0.2.0.0 – 2020-01-05

• After a discussion with phadej, we’re doing away with the flags, and splitting the optics out into their own separate library
• Removed unnecessary inline pragmas

0.1.0.0 – 2020-01-05

• Do away with the typeclasses, and just provide prisms + synonyms
• Continued performance improvements to decoding
• Corrected benchmarks

0.0.1.0 – 2020-01-03

• First version. Released on an unsuspecting world.
• Preliminary release
