You know what keeps happening again and again? That's right, it's Allegro 5 releases! It's literally been exactly a year since the previous release, it's amazing how much time gets taken up by having a day job!

Anyway, as always you can download the sources and MinGW binaries on GitHub (get dependencies here). You can MSVC binaries from Nuget and Ubuntu binaries from a PPA. Homebrew binaries are forthcoming.

Here's the changelog:

Changes from 5.2.4 to 5.2.5 (February 2019)

The main developers this time were: Sebastian Krzyszkowiak, SiegeLord, Elias Pschernig, Bruce Pascoe, Aldrik Ramaekers, Firat Salgur.

Core:

• Try to identify bitmap format for unknown extensions.

  
  

• Add some missing OpenGL 4.3 functions.

  
  

• Add al_create_thread_with_stacksize to create threads with a custom stack size. (Aldrik Ramaekers)

  
  

• Add al_get_system_id function, letting you disambiguate platforms at runtime.

Graphics:

• Add al_get_monitor_dpi to query the DPI of a monitor.

  
  

• Add new API for making blender a bitmap-local state (like transformations), which can simplify some code. See al_set_bitmap_blender and the related APIs. Also see the ex_blend_target example.

  
  

• Added al_transpose_transform. This is useful for rotation transformations.

  
  

• Rework internal GLES support for better portability.

  
  

• Don't force POT bitmaps on GLES.

  
  

• Fix repeated bitmap locking on OpenGL.

Android:

• Various documentation and other improvements (Christian Mauduit).

  
  

• Fix OpenGL version reporting after display creation.

iOS:

• Fix OpenGL version reporting after display creation.

Linux:

• Improve linux joystick detections.

  
  

• Fix a number of memory leaks/crashes in the audio addon when using pulseaudio/alsa. (Julian Smythe)

  
  

• Fix compilation with Mesa 18.2.5 and later.

  
  

• Fix OpenGL version reporting after display creation (Edgar Reynaldo).

  
  

• Fix requesting specific OpenGL versions via display options (Edgar Reynaldo).

OSX:

• Make al_get_monitor_info return the correct values for Retina displays.

  
  

• Fix vsync on OSX 10.14+.

RaspberryPi:

• Fix OpenGL version reporting after display creation.

Windows:

• Fix toggling of menu checkboxes by id.

  
  

• Fix al_draw_indexed_primitive while using Direct3D.

  
  

• Fix crash when passing NULL display to al_show_native_file_dialog while using ALLEGRO_FILECHOOSER_FOLDER.

  
  

• Fix OpenGL version reporting after display creation (Edgar Reynaldo).

  
  

• Fix requesting specific OpenGL versions via display options (Edgar Reynaldo).

SDL:

• Sebastian Krzyszkowiak has spent a lot of effort to making the SDL backend usable as a nearly fully featured Allegro backend. You can use it on platforms native Allegro implementations do not support (such as emscripten, etc.).

Addons:

• Better logging when failing to load a resource.

  
  

• Fix a memory leak when destroying a mixer with attached streams.

  
  

• Fix a memory leak in the audio destroying a mixer with attached streams.

Acodec addon:

• Allow modules to loop properly when the user hasn't specified loop points. (Todd Cope)

Audio addon:

• Better support for big endian. (Douglas Mencken)

TTF addon:

• Added support of HarfBuzz in FreeType (Arves100).

Documentation:

• Source links now point to the correct commit on GitHub.

  
  

• General improvements and clarifications.

Examples:

• Add ex_blend_target.

I just want to say I really appreciate the work you guys put into these.

I went looking through SDL documentation the other day and honestly, I wonder why people actually use it over Allegro / SDL was more popular. The API is rather ugly, they split the library into many sub-libraries just like Allegro (libmixer is a completely separate download from sdl!??!!), and they don't offer many functions that Allegro does.

Excellent work, downloading now

Edit: I'm getting Opus issues- harks back to NiteHackr in the 5.2.4 release thread. No linker errors though; just a failure to load the stream at runtime. I've got libopus0 and libopusfile0 installed.

Using -lopusfile -lopus doesn't seem to help, and ldd reports that my executable doesn't depend on either library. Am I missing something?

Maybe the version is too low ?

opus 1.2.1 -> 1.3

opusfile 0.8 -> 0.11

Is there a regular release schedule or did something particular happen (or was it just a quiet day in Siege Mansions? )

I think SiegeLord was just pointing out the updates to the Windows dependencies bundled in allegro_winpkg. Does anyone know the minimum required versions of libopus/libopusfile? I've got 1.12/0.9 respectively.

ldd reports that compiling with Ubuntu 18.04's stock Allegro 5.2.3 adds libopus.so and libopusfile.so to my executable's dependencies.

Nice work.

There's a comment on liballeg about some commits not being in 5.2.5 yet, so I'm delaying my binaries a bit.

I can't get theora to build this time. It's being cranky...

Xiph.org is clearly ruining our builds. They must be stopped.

I think I'm just gonna build from master. But there's an important patch for 4.4.3 that I want to include.

All the commits that should be there are in fact there.

https://github.com/liballeg/allegro5/compare/5.2.5.0...master

So the OpenGL version reporting and selection is not meant to be committed?

That doesn't show what you think it does. Here are the commits in the release: https://github.com/liballeg/allegro5/commits/5.2.5.0

I wonder why they don't agree?

My guess: if you rebase a commit then it's not the same commit (different hash)?

https://github.com/liballeg/allegro5/compare/5.2.5.0...master shows the commits that were added to master since the last common commit between it and 5.2.5 branch. https://github.com/liballeg/allegro5/compare/5.2.5.0..master shows the differences between the tips of both branches, but not commits (not sure how it would show that).

EDIT 5
There was a bug in PhysFS 3.0.1 that has been fixed and superceded by PhysFS 3.0.2. I updated the binaries to use the new version of physfs. The bug would cause physfs_init to fail on Windows 10. See https://github.com/liballeg/allegro5/issues/1029 for details.

The links stayed the same, but the files were updated. So if you downloaded binaries from before today (03/19/2019 16:20 GMT) please download them again.

Binaries are forthcoming. I couldn't get opus and openssl to build with MSYS alone, so I won't be providing them. Pretty much everything else you could think of will be included.

32 bit first, and then 64 bit as I have time.

EDIT
Here's 32 bit Allegro 5.2.5 built with GCC 8.1 using MinGW-W64.

Allegro525_GCC81_MinGW-W64_i686_posix_dwarf.7z
EDIT4
NM. xD

It includes all the dependencies, debugging and release dynamic and static allegro monoliths, example programs, demos, test programs, chm manual, and a batch script to setup a build environment and to run the examples and demos and tests.

I'm in the middle of updating my compile guide too. Gave it a fresher look and better formatting.

And oh yeah, here's a couple tasty treats for you :

Allegro525 CHM Manual

CMake 3.14rc4 CHM Manual

EDIT
It seems there is a bug in PhysFS that makes physfs_init return 0 and fail in version 3.0.1. As soon as it is fixed I will update all the packages.

Oh my! A CMake manual in CHM format? Thanks!

I've updated the Nuget and MinGW packages to deal with the PhysFS issue on Windows 10. PhysFS is now version 3.0.2.
