0.4.4 2025-07-31

• Optimization: Blaze.ByteString.Builder.Char.Utf8.fromText = Data.Text.Encoding.encodeUtf8Builder rather than going through String. (Alex Biehl, PR #11 https://github.com/blaze-builder/blaze-builder/pull/11)
• Tested with GHC 8.0 - 9.12.2

0.4.3 2025-05-15

• Fix computation of max buffer overhead on 32 bit platforms (sternenseemann, PR #8 https://github.com/blaze-builder/blaze-builder/pull/8)
• Drop support for GHC 7, bytestring < 0.10.4 and text < 1.1.2
• Tested with GHC 8.0 - 9.12.2

0.4.2.3 2023-08-27

• Fix compilation warnings concerning non-canonical mappend
• Support bytestring-0.12
• Support text-2.1
• Tested with GHC 7.0.4 to 9.8.1 alpha3

0.4.2.2

• Support GHC 9.2

0.4.2.1

• Bump cabal file to Cabal >= 1.10

0.4.2.0

• Make semigroup instances unconditional
• Support bytestring-0.11
• Support semigroups-0.19

0.4.1.0

• Gain compatibility with the Semigroup/Monoid proposal
• Add Word8 HTML escaping builders
• Speed up fromHtmlEscapedText and fromHtmlEscapedLazyText

0.4.0.2

• Fixed warnings on GHC 7.10, courtesy of Mikhail Glushenkov.

0.4.0.1

• Tightened the version constraints on the bytestring package for GHC 7.8

0.4.0.0

• This is now a compatibility shim for the new bytestring builder. Most of the old internal modules are gone. See this blog post for more information:

  http://blog.melding-monads.com/2015/02/12/announcing-blaze-builder-0-4/

• The 'Blaze.ByteString.Builder.Html.Utf8.fromHtmlEscaped*' functions now strip out any ASCII control characters present in their inputs. See https://github.com/lpsmith/blaze-builder/issues/1 for more information.

0.3.3.0

• exposed the 'Buffer' constructor to enable keeping around a pool of buffers.

0.3.2.0

• added 'writeToByteString' to construct a strict bytestring in a single step. We can actually view 'Write's as strict-bytestring builders.

0.3.1.1

• Changed imports of Foreign.Unsafe to make it GHC 7.8 compatible
• -Wall clean on GHC 7.0 - 7.6

0.3.1.0

• Widened dependencies on text and bytestring

0.3.0.1

• Fix build warning in Blaze.ByteString.Builder.Word (contributed by Greg Weber)

0.3.0.1

• Remove comparison to the 'text' library encoding functions of 'Blaze.Builder.Char.Utf8.fromText' and 'Blaze.Builder.Char.Utf8.fromLazyText'. Bryan O'Sullivan reported that on his 64-bit system with GHC 7.0.3 the 'text' library is 5x faster than the 'blaze-builder' library.

0.3.0.0

• Renamings in internal modules: WriteIO -> Poke and associated functions.

0.2.1.4

• Fixed bug: appending to 'chunkedTransferEncoding somebuilder' also encoded the appended builder, which is obviously wrong.

0.2.1.3

• Fixed bug: 'chunkedTransferTerminator' is now correctly set to "0\r\n\r\n".

0.2.1.2

• Add 'MonoPatBinds' language extension to all relevant files to solve the issues caused by GHC bug http://hackage.haskell.org/trac/ghc/ticket/4498

0.2.1.1

• Reexport 'Write' datatype and 'fromWriteList', 'fromWriteSingleton', 'fromWrite' functions together with writes and builders for storables.
• Add 'MonoPatBinds' language extension to (hopefully) solve the issues caused by GHC bug http://hackage.haskell.org/trac/ghc/ticket/4498

0.2.1.0

Incorporated several design changes:

• Writable buffer range is now represented in a packed form. This improves speed slightly, as less currying is used.
• Writes are abstracted such that their internal representation can be exchanged without breaking other library code.
• Writes are represented in a form that allows for efficient monoid instances for branching code like UTF-8 encoding. For single character encoding this results currently in a slight slowdown due to GHC not recognizing the strictness of the returned value. This will be fixed in the future.
• BuildSteps support returning a result in Done, which enables to implement a Put monad using CPS.
• chunked list writes were removed, as they result in worse performance when writing non-trivial lists. (cf. benchmarks)
• An internal buffering abstraction is introduced, which is used both by the adaption of the binary package, as well as by the blaze-builder-enumeratee package, to execute puts and builders. It will be used later also by the execution functions of the blaze-builder package.

Implemented new functionality

• Blaze.ByteString.Builder.HTTP provides a builder transformer for doing in-buffer chunked HTTP encoding of an arbitary other builder.
• Blaze.ByteString.Builder.Char8 provides functions to serialize the lower 8-bits of characters similiar to what Data.ByteString.Char8 provides for bytestrings.

0.2.0.3

Loosen 'text' dependency to '>= 0.10 && < 0.12'

0.2.0.2

Fixed bug: use ' instead of ' for HTML escaping '

0.2.0.1

Added a missing benchmark file.

blaze-builder-0.2.0.0

Heavily restructured 'blaze-builder' such that 'Blaze.ByteString.Builder' serves as a drop-in replacement of 'binary:Data.Binary.Builder' which it improves upon with respect to both speed as well as expressivity. See the documentation and the benchmarks for details on improvements and new functionality.

Changed module structure: Blaze.ByteString.Builder.Core -> Blaze.ByteString.Builder Blaze.ByteString.Builder.Utf8 -> Blaze.ByteString.Builder.Char.Utf8 Blaze.ByteString.Builder.Html -> Blaze.ByteString.Builder.Html.Utf8

Changed function names: writeByte -> writeWord8 fromByte -> fromWord8 fromWriteList -> fromWrite1List

Possibly performance sensitive implementation changes:

• 'fromByteString' and 'fromLazyByteString' check now if a direct insertion of the bytestring(s) would be cheaper than copying it. See their documentation on how to recover the old behaviour.

Deprecated functions: 'empty' : use 'mempty' instead 'singleton': use 'fromWord8' instead 'append' : use 'mappend' instead

blaze-builder-0.1

This is the first version of 'blaze-builder'. It is explicitely targeted at fast generation of UTF-8 encoded HTML documents in the 'blaze-html' and the 'hamlet' HTML templating libraries.
