### [3.2.4] 2020-11-13

  * Fixed: code clean-up

### [3.2.3] 2020-11-12

  * Fixed: constraints in the form of `X || Y, >=Y.1` and other such complex constructs were in some cases being optimized into a more restrictive constraint

### [3.2.2] 2020-10-14

  * Fixed: internal code cleanups

### [3.2.1] 2020-09-27

  * Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
  * Fixed: normalization of beta0 and such which was dropping the 0

### [3.2.0] 2020-09-09

  * Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0
  * Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience

### [3.1.0] 2020-09-08

  * Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 3.0.1
  * Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package

### [3.0.1] 2020-09-08

  * Fixed: handling of some invalid -dev versions which were seen as valid

### [3.0.0] 2020-05-26

  * Break: Renamed `EmptyConstraint`, replace it with `MatchAllConstraint`
  * Break: Unlikely to affect anyone but strictly speaking a breaking change, `*.*` and such variants will not match all `dev-*` versions anymore, only `*` does
  * Break: ConstraintInterface is now considered internal/private and not meant to be implemented by third parties anymore
  * Added `Intervals` class to check if a constraint is a subsets of another one, and allow compacting complex MultiConstraints into simpler ones
  * Added `CompilingMatcher` class to speed up constraint matching against simple Constraint instances
  * Added `MatchAllConstraint` and `MatchNoneConstraint` which match everything and nothing
  * Added more advanced optimization of contiguous constraints inside MultiConstraint
  * Added tentative support for PHP 8
  * Fixed ConstraintInterface::matches to be commutative in all cases

### [2.0.0] 2020-04-21

  * Break: `dev-master`, `dev-trunk` and `dev-default` now normalize to `dev-master`, `dev-trunk` and `dev-default` instead of `9999999-dev` in 1.x
  * Break: Removed the deprecated `AbstractConstraint`
  * Added `getUpperBound` and `getLowerBound` to ConstraintInterface. They return `Composer\Semver\Constraint\Bound` instances
  * Added `MultiConstraint::create` to create the most-optimal form of ConstraintInterface from an array of constraint strings

### [1.7.2] 2020-12-03

  * Fixed: Allow installing on php 8

### [1.7.1] 2020-09-27

  * Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
  * Fixed: normalization of beta0 and such which was dropping the 0

  * Fixed: some doctypes

### [1.5.1] 2020-01-13

  * Fixed: Parsing of aliased version was not validating the alias to be a valid version

### [1.5.0] 2019-03-19

  * Added: some support for date versions (e.g. 201903) in `~` operator
  * Fixed: support for stabilities in `~` operator was inconsistent

  * Break: `SpecificConstraint` renamed to `AbstractConstraint`.
  * Break: `LinkConstraintInterface` renamed to `ConstraintInterface`.
  * Break: `VersionParser::parseNameVersionPairs` was removed.

The Future of Digital Wallets: How Mobile Payments are Shaping the Financial Landscape

Digital wallets have fundamentally transformed how we manage money, offering a streamlined, secure, and highly efficient method for handling payments and transactions. By consolidating credit, debit, and loyalty card information into a single app, digital wallets simplify the payment process and eliminate the need for physical cards, enhancing both convenience and security.
As digital wallets evolve, they are integrating advanced features that push the boundaries of traditional payment methods. Biometric authentication, such as fingerprint and facial recognition, adds an extra layer of security, ensuring that only authorized users can access their payment information. Real-time transaction alerts provide instant notifications for every transaction, allowing users to monitor their spending and detect any unauthorized activity swiftly. Budgeting tools within digital wallets offer personalized insights and financial management capabilities, helping users track their expenses and plan their budgets more effectively.
The growing adoption of digital wallets is fueled by their ease of use and the increasing demand for contactless payment solutions. As technology advances, digital wallets are likely to incorporate even more innovative features, such as artificial intelligence for personalized financial advice, integrated loyalty programs for seamless rewards management, and cross-border transaction capabilities for global shopping convenience.
The integration of these features is reshaping the financial landscape by making transactions not only faster but also more secure and user-friendly. The future of digital wallets is set to further revolutionize how we handle our finances, offering an all-encompassing solution that caters to the evolving needs of modern consumers. As digital wallets continue to advance, they will play an increasingly central role in shaping the future of financial interactions, driving the global shift towards a more digital and cashless economy.
