- flag updates
- configurable GRL
- configurable trigger chains
- configurable object working points, including extra ones
- support of EMTopo jets
- updated photon cleaning + pointing correction
- introduction of CutManager
- fix jet selector with b-tag working point
- object scale factors

EasyjetPlus:
- first version

bbbbAnalysis:
- addition of b-jet GRL

bbttAnalysis:
- new variables
- trigger selections
- move MMC computation post event selections

bbyyAnalysis:
- full systematics support
- new variables, non-resonant BDT inputs + resonant PNN
- updated jet sorting + Hbb + VBF selections
- EasyjetPlus postprocessing
- overlap removal ON

New analysis packages:
- bbVV
- bbll
- lltt
- ttHH

Requires AthAnalysis,24.2.38 (slow start up due to ATLINFR-5215)

Major reorganisation:
- Rearranged some module names for a more consistent naming scheme
- Reorganised CI tests and added capability to run all locally
- Flags are locked centrally after creation, only modified by yaml or CLI
- Moved container name specification into yaml
- Move CP alg configuration to use ConfigBlock/ConfigAccumulator
  - This changes the overlap removal handling in the ntuples to write out a decoration instead of OR-ed containers due to limitations in the output tree alg.

New features:
- Permit multiple TTrees to be configured from yaml
- Convert of flags.Analysis into ConfigItem class that behaves like an immutable dict
- Generalise HH truth decay algorithm to handle multiple decay modes
- Optimise TTree output by selecting branches for systematic variations
- Add linking between nominal and systematic variation objects
- Add an alg for creating output view containers holding objects passing selection for any systematic variation

Fixes:
- Use MET ntuple maker for MET branches
- Disable overlap removal branches for MET

Documentation:
- Slight reorganisation of central docs
- Expanded the yybb README

Requires AthAnalysis,24.2.20

Major reorganisation:
- first tag since easyjet/hh4b-analysis -> easyjet/easyjet renaming
- split HH4bAnalysis package into (bbbb/bbyy/bbtt)Analysis

Generic new features
- all object types supported with calibration & (systematics aware) object selectors
- switch systematics on/off in output with branch-level granularity
- AOD and boost histogram output
- hierarchical yaml

Features for bbtautau
- Decorators for lepton charge and tau nProng
