- Pharo is an open-source Smalltalk environment that is highly active with many contributors and projects. It has a large community and is used both for academic research and commercial applications. - Pharo 3 was recently released in April 2014 and included many improvements and changes while remaining easy to adopt. Development is already underway on Pharo 4, with additional changes planned. - Upcoming work includes first-class variables to improve reflection, a new one-file image format, and advanced reflection capabilities using meta-objects. The goal is to continue enhancing Pharo's functionality while keeping it approachable.

- 42. New Inspector Unify Inspector and Explorer Make specialised inspectors visible
- 43. Athens: Vector Graphics New API for Vector Graphics Independent of Backend For now: Cairo Balloon3D for Debugging Future: OpenGL
- 44. Athens: Demo
- 45. Opal Compiler Uses RB AST ! IRBuilder: Bytecode backend with high-level builder Much easier to change Basis for advanced Reflection

- 49. A lot of 界鞄温稼乙艶
- 50. But just one iteration
- 51. Pharo4
- 52. Pharo4 Again: To be released Spring 2015 Already 175 updates 480 Issues closed Very stable
- 53. For example Improved Refactorings 6MB Deployment Image ifTrue: on non-Booleans Browser and Tool cleanups Context Cleanup (MethodContext/ContextPart merge)
- 55. In Progress
- 56. First Class Variables First class Instance Variables (Slots) ! First class globals + class variables
- 57. For what? Allows programmers to define behavior Easy reflection on variable access Break on variable read, for example
- 58. Property Slots Object subclass: #PropertyObject layout: PointerLayout slots: { #ivar. #property1 => PropertySlot. #property2 => PropertySlot. ... #propertyN => PropertySlot. }
- 59. Property Slots Object subclass: #PropertyObject layout: PointerLayout instanceVariables: { #ivar. #property1 => PropertySlot. #property2 => PropertySlot. ... #propertyN => PropertySlot. }

- 61. More in Paper from OOPSLA
- 62. Advanced Reflection Partial Behavioral Reflection Associate MetaObject with structural object Slots, Globals AST nodes
- 63. The Meta Link

- 66. One File Pharo .sources, .changes. .image ! It is time to simplify that!
- 67. Epicea Replace .changes High level model: aggregate changes (refactoring) serialized to disk independent of source model
- 69. Sources It is 2014: Memory is cheap. Complexity is expensive Why not just put the sources in the image? Externalize when needed (small devices) Code history is in Monticello (or Git)
- 70. Bootstrap Create an image from a git repository Control what the image contains Easier to make changes Enforces Modularity
- 71. Boostrap Working for Pharo3 as a prototype ! Can we even use this for Pharo4 on the build server?
- 72. And more GT Tools VM related news Spur, Sista, 64bit .. there are lots of talks here
