## [1.0.0](https://github.com/redis/hiredis/tree/v1.0.0) - (2020-08-03)

Announcing Hiredis v1.0.0, which adds support for RESP3, SSL connections, allocator injection, and better Windows support! :tada:

[Full Changelog](https://github.com/redis/hiredis/compare/v0.14.1...v1.0.0)

**BREAKING CHANGES**:

* `redisOptions` now has two timeout fields.  One for connecting, and one for commands.  If you're presently using `options->timeout` you will need to change it to use `options->connect_timeout`. (See [example](https://github.com/redis/hiredis/commit/38b5ae543f5c99eb4ccabbe277770fc6bc81226f#diff-86ba39d37aa829c8c82624cce4f049fbL36))

* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now protocol errors. This is consistent
  with the RESP specification. On 32-bit platforms, the upper bound is lowered to `SIZE_MAX`.

* `redisReplyObjectFunctions.createArray` now takes `size_t` for its length parameter.

## [1.0.0-rc1](https://github.com/redis/hiredis/tree/v1.0.0-rc1) - (2020-07-29)

_Note:  There were no changes to code between v1.0.0-rc1 and v1.0.0 so see v1.0.0 for changelog_

### 0.14.1 (2020-03-13)

* Adds safe allocation wrappers (CVE-2020-7105, #747, #752) (Michael Grunder)

### 0.14.0 (2018-09-25)
**BREAKING CHANGES**:

* Change `redisReply.len` to `size_t`, as it denotes the the size of a string

  User code should compare this to `size_t` values as well.
  If it was used to compare to other values, casting might be necessary or can be removed, if casting was applied before.

* Make string2ll static to fix conflict with Redis (Tom Lee [c3188b])
* Use -dynamiclib instead of -shared for OSX (Ryan Schmidt [a65537])

* Makefile - Compatibility fixes (Dimitri Vorobiev [3238cf, 12a9d1])
* Makefile - Fix make install on FreeBSD (Zach Shipko [a2ef2b])
* Makefile - don't assume $(INSTALL) is cp (Igor Gnatenko [725a96])
* Separate side-effect causing function from assert and small cleanup (amallia [b46413, 3c3234])
* Don't send negative values to `__redisAsyncCommand` (Frederik Deweerdt [706129])
* Fix leak if setsockopt fails (Frederik Deweerdt [e21c9c])
* Fix libevent leak (zfz [515228])
* Clean up GCC warning (Ichito Nagata [2ec774])
* Keep track of errno in `__redisSetErrorFromErrno()` as snprintf may use it (Jin Qing [25cd88])
* Solaris compilation fix (Donald Whyte [41b07d])
* Reorder linker arguments when building examples (Tustfarm-heart [06eedd])
* Keep track of subscriptions in case of rapid subscribe/unsubscribe (Hyungjin Kim [073dc8, be76c5, d46999])
* libuv use after free fix (Paul Scott [cbb956])
* Properly close socket fd on reconnect attempt (WSL [64d1ec])
* Skip valgrind in OSX tests (Jan-Erik Rediger [9deb78])
* Various updates for Travis testing OSX (Ted Nyman [fa3774, 16a459, bc0ea5])
* Update libevent (Chris Xin [386802])
* Change sds.h for building in C++ projects (Ali Volkan ATLI [f5b32e])
* Use proper format specifier in redisFormatSdsCommandArgv (Paulino Huerta, Jan-Erik Rediger [360a06, 8655a6])
* Better handling of NULL reply in example code (Jan-Erik Rediger [1b8ed3])
* Prevent overflow when formatting an error (Jan-Erik Rediger [0335cb])
* Compatibility fix for strerror_r (Tom Lee [bb1747])
* Properly detect integer parse/overflow errors (Justin Brewer [93421f])
* Adds CI for Windows and cygwin fixes (owent, [6c53d6, 6c3e40])
* Catch a buffer overflow when formatting the error message
* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
* Fix warnings, when compiled with -Wshadow
* Make hiredis compile in Cygwin on Windows, now CI-tested
* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
  protocol errors. This is consistent with the RESP specification. On 32-bit
  platforms, the upper bound is lowered to `SIZE_MAX`.

* Remove backwards compatibility macro's

This removes the following old function aliases, use the new name now:

| Old                         | New                    |
| --------------------------- | ---------------------- |
| redisReplyReaderCreate      | redisReaderCreate      |
| redisReplyReaderCreate      | redisReaderCreate      |
| redisReplyReaderFree        | redisReaderFree        |
| redisReplyReaderFeed        | redisReaderFeed        |
| redisReplyReaderGetReply    | redisReaderGetReply    |
| redisReplyReaderSetPrivdata | redisReaderSetPrivdata |
| redisReplyReaderGetObject   | redisReaderGetObject   |
| redisReplyReaderGetError    | redisReaderGetError    |

* The `DEBUG` variable in the Makefile was renamed to `DEBUG_FLAGS`

Previously it broke some builds for people that had `DEBUG` set to some arbitrary value,
due to debugging other software.
By renaming we avoid unintentional name clashes.

Simply rename `DEBUG` to `DEBUG_FLAGS` in your environment to make it working again.

### 0.13.3 (2015-09-16)

* Revert "Clear `REDIS_CONNECTED` flag when connection is closed".
* Make tests pass on FreeBSD (Thanks, Giacomo Olgeni)


If the `REDIS_CONNECTED` flag is cleared,
the async onDisconnect callback function will never be called.
This causes problems as the disconnect is never reported back to the user.

### 0.13.2 (2015-08-25)

* Prevent crash on pending replies in async code (Thanks, @switch-st)
* Clear `REDIS_CONNECTED` flag when connection is closed (Thanks, Jerry Jacobs)
* Add MacOS X addapter (Thanks, @dizzus)
* Add Qt adapter (Thanks, Pietro Cerutti)
* Add Ivykis adapter (Thanks, Gergely Nagy)

All adapters are provided as is and are only tested where possible.

### 0.13.1 (2015-05-03)

This is a bug fix release.
The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
Other non-C99 code can now use hiredis as usual again.
Sorry for the inconvenience.

* Fix memory leak in async reply handling (Salvatore Sanfilippo)
* Rename struct member to avoid name clash with pre-c99 code (Alex Balashov, ncopa)

### 0.13.0 (2015-04-16)

This release adds a minimal Windows compatibility layer.
The parser, standalone since v0.12.0, can now be compiled on Windows
(and thus used in other client libraries as well)

* Windows compatibility layer for parser code (tzickel)
* Properly escape data printed to PKGCONF file (Dan Skorupski)
* Fix tests when assert() undefined (Keith Bennett, Matt Stancliff)
* Implement a reconnect method for the client context, this changes the structure of `redisContext` (Aaron Bedra)

### 0.12.1 (2015-01-26)

* Fix `make install`: DESTDIR support, install all required files, install PKGCONF in proper location
* Fix `make test` as 32 bit build on 64 bit platform

### 0.12.0 (2015-01-22)

* Add optional KeepAlive support

* Try again on EINTR errors

* Add libuv adapter

* Add IPv6 support

* Remove possibility of multiple close on same fd

* Add ability to bind source address on connect

* Add redisConnectFd() and redisFreeKeepFd()

* Fix getaddrinfo() memory leak

* Free string if it is unused (fixes memory leak)

* Improve redisAppendCommandArgv performance 2.5x

* Add support for SO_REUSEADDR

* Fix redisvFormatCommand format parsing

* Add GLib 2.0 adapter

* Refactor reading code into read.c

* Fix errno error buffers to not clobber errors

* Generate pkgconf during build

* Silence _BSD_SOURCE warnings

* Improve digit counting for multibulk creation


### 0.11.0

* Increase the maximum multi-bulk reply depth to 7.

* Increase the read buffer size from 2k to 16k.

* Use poll(2) instead of select(2) to support large fds (>= 1024).

### 0.10.1

* Makefile overhaul. Important to check out if you override one or more
  variables using environment variables or via arguments to the "make" tool.

* Issue #45: Fix potential memory leak for a multi bulk reply with 0 elements
  being created by the default reply object functions.

* Issue #43: Don't crash in an asynchronous context when Redis returns an error
