# Change Log #
All notable changes to this project will be documented in this file.

## [Unreleased] ##
- **Added** usage of `emplace_back()` when dealing with vector
  insertions. (Performance). Whole tree completed.
- **Added** usage of `nullptr`. Whole tree completed.
- **Added** usage of type aliases.
- **Deleted** unused includes.
- **Fixed** C-style headers in C++ files.
- **Fixed** hardcoded function names (in error messages).
- **Fixed** unchecked function return values.
- **Improved** the C++ exception handling. Namely handle all exceptions
  thrown before `main()` begins executing.
- **Made** move assignment operators and move constructors
  `noexcept`. (Performance).
- **Reduced** the scope of variables.
- **Replaced** `atoi()` with `strtol()`. Multiple occurrences.
- **Usage** of `auto` in order to avoid duplicating the type name.

## [3.5.8] - 2026-01-17 ##
- **Added** command `/log` (management of log files).

## [3.5.7] - 2026-01-01 ##
- **Added** micro optimizations. Multiple occurrences.
- **Added** option `save_backlogs_to_disk` (string). Can be `no`, `both`,
  `channels` or `private`. Defaults to `both`.
- **Added** usage of `__restrict`.
- **Changed** the program to during the make phase perform basic checks on
  functions which accept buffers and sizes.
- **Changed** the program to, additionally, display the Curses and TLS
  library versions when called by the `-v` flag.
- For classes that declares a destructor, also declare a:
  1. copy assignment operator
  2. copy constructor
  3. move assignment operator
  4. move constructor
- **Improved** the C++ exception handling.
- **Replaced** `memcmp()` with `timingsafe_memcmp()` - one occurrence.
- **Replaced** preprocessor defines with regular variables.
- **Switched** memory allocation/deallocation method to new/delete for C++
  files. A few occurrences only.

### Windows ###
- **Upgraded** to [Curl](https://curl.se/) 8.17.0
- **Upgraded** to [LibreSSL](https://www.libressl.org/) 4.2.1

## [3.5.6] - 2025-10-11 ##
- **Added** command `/nsid` (NickServ identify).
- **Added** command `/utctime`.
- **Added** command-line option `-h`. (Sets the bind host)
- **Added** small tab completion improvements.
- During file creation, took care to give it the most restrictive
  permissions possible. Multiple occurrences.
- **Fixed** segmentation fault on OpenBSD 7.8 and greater due to a type
  change of the global variable `malloc_options` which is now an
  immutable char pointer. Better to not set it at all, not even at
  file scope. It had been good if the declaration of `malloc_options`
  had been provided within a system header, the segmentation fault had
  instead resulted in a compilation error.
- **Improved** the thread safety. Fixed potential data races found by TSan.

### Windows ###
- **Upgraded** to [LibreSSL](https://www.libressl.org/) 4.1.1

## [3.5.5] - 2025-05-17 ##

  reduced duplication.
- **Changed** `squeeze_text_deco_wide()` in order to make it more accurate
  for its task.
- **Changed** the output of `/set`. When called without any arguments it
  lists all settings by columns.
- **Changed** the program to kill the IRC server connection if event
  welcome is received more than once. Which for example can happen if
  ZNC loses its IRC server connection, and that causes troubles.
- **Changed** the program to replace less than/greater than signs with
  `<` and `>` respectively, this in notifications.
- **Fixed** a few Clang Tidy warnings.
- **Fixed** building with `GNUMAKEFLAGS=--shuffle=reverse`. Reported by
  Lucas Nussbaum. Thanks!
- **Fixed** conversion from type `A` -> `B`, possible loss of
  data. Multiple occurrences.

  messages.
- **Fixed** option `notifications`.
  (Did not take effect on private messages).

- The [PDC](https://pdcurses.org/) library has been rebuilt with the
  option `UTF8=Y` which makes PDCurses ignore the system locale. So
  for Windows computers running Swirc UTF-8 is now forced. This means
  you should enable the option **Use Unicode UTF-8 for worldwide
  language support**. In order to do so under Windows 10:
  1. Language preferences
  2. Administrative language settings
  3. Change system locale
  4. Check the option and click OK

### Changed ###
- The default theme. Color codes that consisted of only one digit were
  changed to use two digits in some cases. For example: ^C3 changed to
  ^C03, ^C5 changed to ^C05, etc. Why? Consider a function call like
  printtext(..., "%s`one or more digits`", Theme(`primary_color`)). If
  the primary color, in this case, consists of only one digit and is
  directly followed by `one or more digits` the result is: one digit
  is lost and a random color will be displayed.

### Fixed ###
- As a fallback, instead of printing out "Printtext Internal Error",
  continue to convert characters even if some are lost due to an
  invalid multibyte sequence.
- Interpretation of color codes in the printtext module. For example:
  ^C123 didn't display '3' before as it should.
