Version 0.8.0

• New command compiler-explorer-browse-opcode-documentation opens a
  website that contains the documentation for the opcode at point.

• ElDoc integration: Doing C-h . (display-local-help) in the ASM
  buffer will now pop up a buffer showing the documentation for opcode
  at point.

• Fixed an issue where sessions were sometimes not properly persisted
  on Emacs exit.

• A detailed error message is now displayed in case restoring a
  previous session fails.

Full Changelog: v0.7.0...v0.8.0

Version 0.7.0

• Minimum Emacs version was bumped to 28.1 from 27.1.

• Tool support: support for compilation tools (e.g. clang-tidy) has
  been added. New command compiler-explorer-add-tool will query the
  user for name of a tool for current language and display a buffer
  showing the tool's output. New commands
  compiler-explorer-set-tool-args and
  compiler-explorer-set-tool-input can be used to set the
  arguments/standard input for the added tools. New command
  compiler-explorer-remove-tool can be used to remove a previously
  added tool. All of these commands can also be invoked from the
  menu.

• The session layout is now restored when restoring a previous
  session. This behavior can be changed by modifying the new
  compiler-explorer-restore-layouts defcustom.

• The session ring is now infinitely sized. The previous behavior was
  to silently remove oldest sessions from the ring when it's size
  reached it's limit. The variable compiler-explorer-sessions that
  previously controlled the ring size has been removed.

Version 0.6.1

• Fixed shortlink generation after URL change in the API.

Full Changelog: v0.6.0...v0.6.1

Version 0.6.0

• Minimum Emacs version was bumped to 27.1 from 26.1.

• New command compiler-explorer-restore-from-link restores a session
  from a shortlink generated by the website externally, or by
  compiler-explorer-make-link.

• compiler-explorer-previous-session can now be called with a prefix
  argument to query for the session to restore. The previous sessions
  can also be selected from the menu.

• New command compiler-explorer-discard-session will discard the
  current or (with prefix argument) selected past session.

• All overlays that relate to the same code block are now highlighted
  when point is inside of them.

• A few small fixes and improvements.

Full Changelog: v0.5.0...v0.6.0

Version 0.5.0

• Implemented colored source line to ASM line mappings with
  overlays. This can be toggled by setting the customizable
  variable compiler-explorer-source-to-asm-mappings or via the
  menu. New command compiler-explorer-jump can be used to jump
  from source line to corresponding ASM line and vice versa.

• Fixed output filters which are not supported by current
  language/compiler being set in the request.

• List of languages in the menu is now sorted, and compilers are
  grouped.

• Fixed an issue where a new session could not be interactively
  created when the default compiler for a language was invalid.

• Switched from the old, and apparently no longer actively
  developed request package for HTTP requests to newer and
  actively developed plz. Note: this makes compiler-explorer
  depend on curl being installed.

• Added better protection against some external package/function
  messing buffer-local variables and modes which are required for
  compiler-explorer. This was done by converting
  compiler-explorer-mode into a globalized minor mode which in
  turn enables an internal buffer-local mode that reliably sets up
  buffer-local variables.

• Various fixes and smaller improvements.

Full Changelog: v0.4.0...v0.5.0

Version 0.4.0

• The "Debug Intrinsics" output filter can now be set.

• Useless (unmodified) sessions are now not persisted.

• The compilation and execution buffers are now updated
  non-destructively, i.e the point and window scroll is preserved
  when possible.

• A menu bar is now available in compiler-explorer sessions.

• New command compiler-explorer-exit kills the current session.

• Documentation for ASM opcodes is now optionally provided via
  eldoc in the compilation buffers. This is controlled by the
  compiler-explorer-document-opcodes defcustom.

• New command compiler-explorer-load-example loads a named
  example for the current language.

• The annoying request--callback: peculiar error message has
  been removed.

• Various fixes and smaller improvements.

Full Changelog: v0.3.0...v0.4.0

Version 0.3.0

• The source buffer now has a header line, with buttons to start a new
  session and to switch layouts.

• Windows are now dedicated to their buffers during CE session. This
  is customizable via compiler-explorer-dedicate-windows.

• The compilation/execution status is now displayed in the header line
  instead of the mode line, as it was often hidden on smaller screens.

• Execution support is now detected for compilers. If a compiler does
  not support execution, a proper message will now be displayed in the
  execution output buffer. The previous behavior was to silently ignore
  this, and the user was not informed of that.
  compiler-explorer-set-compiler can now be called interactively with
  a prefix argument to select a compiler from the list of compilers that
  support execution.

• The sessions file now uses lisp-data-mode.

• Byte compilations errors/warnings were fixed.

Full Changelog: v0.2.0...v0.3.0

Version 0.2.0

• New hook compiler-explorer-params-change-hook which runs when
  compilation parameters change (like arguments, execution input string).

• Execution output buffer now recognizes ANSI escape codes. With
  this, e.g. AddressSanitizer output is shown properly.

• Lines in ASM buffer are now always truncated.

• Various fixes
