# DBI 1.1.0
## New features
- New `DBIConnector` class (#280).
- Specify `immediate` argument to `dbSendQuery()`, `dbGetQuery()`,
`dbSendStatement()` and `dbExecute()` (#268).
- Use specification for `dbGetInfo()` (#271).
- `dbUnquoteIdentifier()` now supports `Id()` objects with `catalog`
members (#266, @raffscallion). It also handles unquoted identifiers
of the form `table`, `schema.table` or `catalog.schema.table`, for
compatibility with dbplyr.
## Documentation
- New DBI intro article (#286, @cutterkom).
- Add pkgdown reference index (#288).
- DBI specification on https://dbi.r-dbi.org/dev/articles/spec now
comes with a table of contents and code formatting.
- Update examples to refer to `params` instead of `param` (#235).
- Improved documentation for `sqlInterpolate()` (#100). Add usage of
`SQL()` to `sqlInterpolate()` examples (#259, @renkun-ken).
- Improve documentation for `Id`.
## Internal
- Add tests for `dbUnquoteIdentifier()` (#279, @baileych).
- `sqlInterpolate()` uses `dbQuoteLiteral()` instead of checking the
type of the input.
- Avoid partial argument match in `dbWriteTable()` (#246, @richfitz).

# rstudioapi 0.11
* `rstudioapi::launcherResourceLimit()` now properly delegates the type
and memory arguments. (#164)
* `rstudioapi` gains the function `highlightUi()`, used to highlight UI
elements in newer versions of RStudio.
* Paths returned from `selectFile()` are now properly marked with
UTF-8 encoding.
* It is now possible for `rstudioapi` to communicate with a parent RStudio
session, for R sessions launched as RStudio jobs. Use
`rstudioapi::isAvailable(child_ok = TRUE)` to assert that it's okay to check
that `rstudioapi` is available and is running within an RStudio job.
* Added `bugReport()`, a helper function for reporting RStudio bugs
on the GitHub issue tracker with an issue template pre-populated
with some helpful diagnostic information.
* Added `userIdentity` and `systemUsername`, used to retrieve information about
the current user.

Backwards compatibility breaks and deprecations
Please manually add any backwards compatibility breaks or deprecations here, in addition to the automatic listing below.
assumptions
Removed deprecated Q.bounded (use Q.finite instead). Deprecated since version 1.0 (issue: #9425) (#18390 by @Smit-create)
Removed deprecated Q.infinitesimal (use Q.zero instead). Deprecated since version 1.0 (issue: #9675) (#18390 by @Smit-create)
Removed deprecated Q.infinity (use Q.infinte instead). Deprecated since version 1.0 (issue: #9426) (#18390 by @Smit-create)
calculus
Deprecated evaluate argument in differentiate_finite for making non-conservative finite differences. (#17881 by @vezeli)
combinatorics
Using Permutation.print_cyclic will raise deprecation warnings (#18033 by @oscarbenjamin, @souravgl0, and @sylee957)
core
Deprecated sympify automatically converting custom objects with __str__ or __repr__ implemented. (#19006 by @sylee957)
BREAKING CHANGE: Basic.has no longer accepts strings as input. For example in SymPy 1.5 you could do Symbol('x').has('x') and the string 'x' passed to has would be sympified to a symbol so that the result would be True. In SymPy 1.6 this will raise an error because the string 'x' can not be sympified using strict sympification. (#19251 by @oscarbenjamin)
Remove deprecated bounded, unbounded and infinitesimal. Deprecated since version 0.7.6 (issue #8071) (#18503 by @Smit-create)
Relational is no longer a subclass of Expr and does not produce nonsensical results in arithmetic operations. This affects all Relational subclasses (Eq, Ne, Gt, Ge, Lt, Le). It is no longer possible to call meaningless Expr methods like as_coeff_Mul on Relational instances. (#18053 by @oscarbenjamin)
Expr now uses cooperative dispatch for binary operations so it is possible for non-Expr Basic subclasses to override the behaviour of e.g. a + b where one of a or b is an instance of Expr. This also means that any non-Expr Basic subclasses can not depend on Expr.__add__ to create Add(a, b): if a class is not a subclass of Expr and wants to define binary operations with Expr it must do so explicitly in its own __add__ method. For classes depending on this this is not a backward compatible change. (#18116 by @oscarbenjamin)
matrices
The Matrix.is_zero property has been renamed to Matrix.is_zero_matrix.
Matrix.is_zero is now always False. This is because in general is_zero means the number zero so a matrix can never be zero.
To get the old behavior of M.is_zero in both old and new versions of sympy use from sympy.core.logic import fuzzy_and; fuzzy_and(m.is_zero for m in M). (#18464 by @sylee957)
polys
BREAKING CHANGE: Poly and PurePoly now subclass Basic rather than Expr. This means that they no longer have various Expr methods such as expand that do not make sense for Poly. Use as_expr to convert the Poly to an Expr before using Expr methods. (#18613 by @oscarbenjamin)
BREAKING CHANGE: Poly instances with different domains now always compare unequal with p1 == p2 and p1.eq(p2). Previously Poly instances that had the same expression and generators would compare equal even if the domains were different. In some cases it might be necessary to specify the domain when comparing e.g. if p == Poly(x, x, domain='QQ'). (#18613 by @oscarbenjamin)
DEPRECATION: Mixing Poly with non-polynomial Expr in binary operations is now deprecated. For example Poly(x, x) * exp(x) will give a deprecation warning but still return the Expr x*exp(x) as before. If the Expr can be converted to Poly (e.g. Poly(x, x) * x) then a Poly will be returned. To get an Expr always use the as_expr method first to convert the Poly to an Expr. To get a Poly always use as_poly to convert the Expr to a Poly. (#18613 by @oscarbenjamin)
DEPRECATION: Passing Poly as the integrand to the integrate function or Integral class is now deprecated. Use the integrate method instead e.g. Poly(x, x).integrate(x) (#18613 by @oscarbenjamin)
printing
Removed deprecated Ccodeprinter (Use C89Printer or C99Printer instead). Deprecated since version 1.1 (Issue : #12220). (#18392 by @risubaba)
Removed deprecated file viewer option in preview. Deprecated since version 0.7.3(Issue: #7018) (#18392 by @risubaba)
Removed deprecated StringIO viewer option in preview. Deprecated since version 0.7.2(Issue: #7083) (#18392 by @risubaba)
sets
Set now uses cooperative dispatch for binary operations so it is possible for non-Set Basic subclasses to override the behaviour of e.g. a + b where one of a or b is an instance of Set. This also means that any non-Set Basic subclasses can not depend on e.g. Set.__add__ to create Union(a, b): if a class is not a subclass of Set and wants to define binary operations with Set it must do so explicitly in its own __add__ method. For classes depending on this this is not a backward compatible change. (#18116 by @oscarbenjamin)
other
Submodule names are no longer imported with from sympy import *. They can still be imported directly like from sympy import core or accessed like sympy.core, or like sys.modules['sympy.simplify'] for modules that share names with SymPy functions. (#18245 by @oscarbenjamve the T/F assumptions of a symbol or expression (#19155 by @smichr)
common_assumptions returns the T/F assumptions in common amongst the given expressions (#19155 by @smichr)
Added a refine_matrixelement function (#18681 by @Saanidhyavaeprecated Q.bounded (use Q.finite instead). Deprecated since version 1.0 (issue: #9425) (#18390 by @Smit-create)
Removed deprecated Q.infinitesimal (use Q.zero instead). Deprecated since version 1.0 (issue: #9675) (#18390 by @Smit-create)
ask(Q.antihermitian()) which earlier generated incorrect results. (#18303 by @czgdp1807)
Improved code in ask function using constructs from cnf module. (#18204 by @JSS95 and @mcpl-sympy)
Fixed bug in ask function: In case of user-defineus_domain now finds singularities in nested fractions (#19047 by @smichr and @ThomasHickman)
singularities has been upgraded to handle more than rational functions (#19047 by @smichr and @ThomasHickman)
fixes operations of AccumBounds (#18803 by @Ryand1234)
periodicity of exponential functions with a non-zero phase component is now calculated. (#18746 by @mohitacecode)
Correct the solution of differentiate_finite for expressions that contain embedded derivatives. (#17881 by @vezeli)
Deprecated evaluate argument in differentiate_finite for making non-conservative finite differences. (#17881 by @vezeli)
Updated docstrings of maximum, minimum, stationary_points and AccumBounds.intersection (#18581 by @mijo2)
Fixes Recursion Error in AccumulationBounds.__pow__ by adding a check on denominator (#18450 by @Smit-create)
combinatorics
Permutation * PermutationGroup and PermutationGroup * Permutation return Coset. (#19139 by @mohitacecode)
Added Coset Class. (#19077 by @mohitacecode and @sylee957)
Added SymmetricPermutationGroup Class. (#19077 by @mohitacecode and @sylee957)
Added schur number utilities in combinatorics (#18667 by @mijo2 and @slacker404)
Raise exception with wrong size in Permutation. (#18587 by @Smit-create)
Added Permutation.conjugacy_class and Permutation.conjugacy_classes for computing conjugacy classes in permutation groups. (#18354 by @lucjon and @sachin-4099)
Fixed Permutation applying for negative integers. (#18032 by @mrocklin and @sylee957)
Added Permutation.apply to use permutation as a symbolic function. (#18032 by @mrocklin and @sylee957)
Using Permutation.print_cyclic will raise deprecation warnings (#18033 by @oscarbenjamin, @souravgl0, and @sylee957)
Cycle class is no longer mutable and can be regarded as a sparse representation of a permutation (#17973 by @sachin-4099)
core
BREAKING CHANGE: Basic.has no longer accepts strings as input. For example in SymPy 1.5 you could do Symbol('x').has('x') and the string 'x' passed to has would be sympified to a symbol so that the result would be True. In SymPy 1.6 this will raise an error because the string 'x' can not be sympified using strict sympification. (#19251 by @oscarbenjamin)

Pow.is_zero is fixed for some cases involving infinite (or possibly infinite) expressions. (#18728 by @oscarbenjamin)
Now finite and infinite are logical opposites in the old assumptions system so e.g. a Symbol declared with finite=False will have infinite=True. (#18726 by @oscarbenjamin)

__getnewargs__() added to Zero, One, NegativeOne, Half. (#18675 by @mohitacecode)

Updated the definition of atoms method of class Basic (#18532 by @mijo2)
basic - sorting in subs is improved so unsorted arguments will prefer replacing more complicated patterns first (e.g. the second derivative before the first derivative). (#18043 by @Psycho-Pirate)

Version 4.8.9
=============
- New features
- significant improvements to regular expression solving
- expose user theory plugin. It is a leaner user theory plugin that was once available.
It allows for registering callbacks that react to when bit-vector and Boolean variables
receive fixed values.
- Bug fixes
- many
- Notes
- the new arithmetic theory is turned on by default. It _does_ introduce regressions on
several scenarios, but has its own advantages. Users can turn on the old solver by setting smt.arith.solver=2.
Depending on feedback, we may turn toggle this default setting again back to smt.arith.solver=2.
Version 4.8.8
=============
- New features
- rewritten NIA (non-linear integer arithmetic) core solver
It is enabled in selected theories as default.
The legacy arithmetic solver remains the overall default in this release
as the rewritten solver shows regressions (on mainly NRA problems).
- recursive function representation without hoisting ite expressions. Issue #2601
- model-based interpolation for quantifier-free UF, arithmetic
- Julia bindings over the C++ API, thanks to ahumenberger
- Bug fixes
- numerous, many based on extensive fuzz testing.
Thanks to 5hadowblad3, muchang, numairmansur, rainoftime, wintered
- Notes
- recursive functions are unfolded with separate increments based on unsat core
analysis of blocking literals that are separate for different recursive functions.
- the seq (string) solver has been revised in several ways and likely shows some
regressions in this release.
Version 4.8.7
=============
- New features
- setting parameter on solver over the API by
solver.smtlib2_log=<filename>
enables tracing calls into the solver as SMTLIB2 commands.
It traces, assert, push, pop, check_sat, get_consequences.
- Notes
- various bug fixes
- remove model_compress. Use model.compact
- print weights with quantifiers when weight is != 1
Version 4.8.6
=============
- Notes
- various bug fixes
- built in support for PIP, thanks to Audrey Dutcher
- VS compilation mode including misc flags for managed packages
Version 4.8.5
=============
- Notes
- various bug fixes
Version 4.8.4
=============
- Notes
- fixes bugs
- a substantial update to how the seq theory solver handles regular
expressions. Other performance improvements to the seq solver.
- Managed .NET DLLs include dotnet standard 1.4 on supported platforms.
- Windows Managed DLLs are strong signed in the released binaries.
Version 4.8.3
=============
- New features
- Native handling of recursive function definitions, thanks to Simon Cruanes
- PB rounding based option for conflict resolution when reasoning about PB constraints.
- Access to numeral constants as a double from the native API.
- Notes
- fixes several bugs discovered since the 4.8.1 release.
Version 4.8.2
=============
- Post-Release.
Version 4.8.1
=============
- Release. Bug-fix for 4.8.0
Version 4.8.0
=============
- New requirements:
- A breaking change to the API is that parsers for SMT-LIB2 formulas return a vector of
formulas as opposed to a conjunction of formulas. The vector of formulas correspond to
the set of "assert" instructions in the SMT-LIB input.
- New features
- A parallel mode is available for select theories, including QF_BV.
By setting parallel.enable=true Z3 will spawn a number of worker threads proportional to the
number of available CPU cores to apply cube and conquer solving on the goal.
- The SAT solver by default handle cardinality and PB constraints using a custom plugin
that operates directly on cardinality and PB constraints.
- A "cube" interface is exposed over the solver API.
- Model conversion is first class over the textual API, such that subgoals created from running a
solver can be passed in text files and a model for the original formula can be recreated from the result.
- This has also led to changes in how models are tracked over tactic subgoals. The API for
extracting models from apply_result have been replaced.
- An optional mode handles xor constraints using a custom xor propagator.
It is off by default and its value not demonstrated.
- The SAT solver includes new inprocessing techniques that are available during simplification.
It performs asymmetric tautology elimination by default, and one can turn on more powerful inprocessing techniques
(known as ACCE, ABCE, CCE). Asymmetric branching also uses features introduced in Lingeling by exploiting binary implication graphs.
Use sat.acce=true to enable the full repertoire of inprocessing methods. By default, clauses that are "eliminated" by acce are tagged
as lemmas (redundant) and are garbage collected if their glue level is high.
- Substantial overhaul of the spacer horn clause engine.
- Added basic features to support Lambda bindings.
- Added model compression to eliminate local function definitions in models when
inlining them does not incur substantial overhead. The old behavior, where models are left
uncompressed can be replayed by setting the top-level parameter model_compress=false.
- Integration of a new solver for linear integer arithmetic and mixed linear integer arithmetic by Lev Nachmanson.
It incorporates several improvements to QF_LIA solving based on
. using a better LP engine, which is already the foundation for QF_LRA
. including cuts based on Hermite Normal Form (thanks to approaches described
in "cuts from proofs" and "cutting the mix").
. extracting integer solutions from LP solutions by tightening bounds selectively.
We use a generalization of Bromberger and Weidenbach that allows avoiding selected
bounds tightenings (https://easychair.org/publications/paper/qGfG).
It solves significantly more problems in the QF_LIA category and may at this point also
be the best solver for your problem as well.
The new solver is enabled only for select SMT-LIB logics. These include QF_LIA, QF_IDL, and QF_UFLIA.
Other theories (still) use the legacy solver for arithmetic. You can enable the new solver by setting
the parameter smt.arith.solver=6 to give it a spin.
- Removed features:
- interpolation API
- duality engine for constrained Horn clauses.
- pdr engine for constrained Horn clauses. The engine's functionality has been
folded into spacer as one of optional strategies.
- long deprecated API functions have been removed from z3_api.h
Version 4.7.1
=============
- New requirements:
- uses stdbool and stdint as part of z3.
- New features:
- none
- Removed features:
- none
- Notes:
This is a minor release prior to a set of planned major updates.
It uses minor version 7 to indicate that the use of stdbool and
stdint are breaking changes to consumers of the C-based API.
Version 4.6.0
=============
- New requirements:
- C++11 capable compiler to build Z3.
- C++ API now requires C++11 or newer.
- New features (including):
- A new string solver from University of Waterloo
- A new linear real arithmetic solver
- Changed behavior for optimization commands from the SMT2 command-line interface.
Objective values are no longer printed by default. They can be retrieved by
issuing the command (get-objectives). Pareto front objectives are accessed by
issuing multiple (check-sat) calls until it returns unsat.
- Removed features:
- Removed support for SMT-LIB 1.x

0.24 2019-10-08
- Fix parsing the text of cells that only contain "0"
These were returned as undef, instead of 0 unless the StandardCurrency
option was used.
- Fix parsing multiple sheets. If the first cell of the new table was empty,
the last defined value of the old table was used instead, if the
real (instead of formatted) values were used.
0.23 2019-10-03
- Add a test and fix for files with text in annotations - these caused
a crash
0.22 2019-10-03
- Lower Perl version requirement back to 5.8
There is no current reason to require more.
- API Change:
Formatting or read errors in the compressed input or the XML are now
fatal errors. Before, they returned the half-parsed data structure.
- read_sxc() and read_xml_file can now also return a fatal error when the
file is not found or not readable instead of returning undef. Pass a true
value to the the StrictError option.
- Bugfix/behaviour change: Cells with leading/trailing newlines now
return those leading/trailing newlines in their values
0.21 2019-10-02
- Add 'StandardCurrency' option to get at unformatted number values
- Support unformatted values for ODS files
- New maintainer Max Maischein (corion@corion.net)

all recursively depending packages can deal with them.
Those packages that need them already add those CONFIGURE_ARGS, at least
pbulk hasn't revealed any issues (thanks jperkin@).
XXX libiconv is in a similar position, so should receive similar
treatment, but at least it only adds the flags if GNU_CONFIGURE=yes
Fixes PR pkg/55487

The distfile contains invalid "." and ".." entries.
Both bsdtar and gtar refuse to unpack this.
The package is not used by any other packages in pkgsrc and upstream is
dead (distfile is from 2004).

Changes from versions 4.0.* to version 4.1.0:
- The "épinards à la crème" release.
- Binary compatible with MPFR 4.0.*, though some minor changes in the
behavior of the formatted output functions may be visible, regarded
as underspecified behavior or bug fixes (see below).
- New --enable-formally-proven-code configure option, to use (when available)
formally proven code.
- Improved __GMP_CC and __GMP_CFLAGS retrieval (in particular for MS Windows).
- Option -pedantic is now always removed from __GMP_CFLAGS (see INSTALL).
- Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
__float128 is used as a fallback if _Float128 is not supported.
- New function mpfr_get_str_ndigits about conversion to a string of digits.
- New function mpfr_dot for the dot product (incomplete, experimental).
- New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
when MPFR has been built with decimal float support).
- New function mpfr_cmpabs_ui.
- New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
- The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
- Shared caches: cleanup; really detect lock failures (abort in this case).
- The behavior of the formatted output functions (mpfr_printf, etc.) with
an empty precision field has improved: trailing zeros are kept in a way
similar to the formatted output functions from C.
- Improved mpfr_add and mpfr_sub when all operands have a precision equal to
twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
- Optimized the tuning parameters for various architectures.
- Improved test coverage to 98.6% of code for x86_64.
- Bug fixes.
- MPFR manual: corrected/completed the mpfr_get_str description in order to
follow the historical behavior and GMP's mpf_get_str function.
- New: optional "make check-exported-symbols", mainly for the MPFR developers
and binary distributions, to check that MPFR does not define symbols with a
GMP reserved prefix (experimental).
- Mini-gmp support: replaced --enable-mini-gmp configure option by
--with-mini-gmp (still experimental, read doc/mini-gmp).
- A GCC bug on Sparc (present at least in old GCC 4.5.3 and 5.5.0 versions),
which made several tests fail when TLS was enabled, is now avoided in the
tests. The MPFR library itself was not affected and normal code using the
MPFR library should not be affected either. Users and distributions that
disabled TLS just because of the test failures can safely re-enable it.

Version 0.51.0
This release continues to add new features to Numba and also contains a significant number of bug fixes and stability improvements.
Highlights of core feature changes include:
The compilation chain is now based on LLVM 10 (Valentin Haenel).
Numba has internally switched to prefer non-literal types over literal ones so as to reduce function over-specialisation, this with view of speeding up compile times (Siu Kwan Lam).
On the CUDA target: Support for CUDA Toolkit 11, Ampere, and Compute Capability 8.0; Printing of SASS code for kernels; Callbacks to Python functions can be inserted into CUDA streams, and streams are async awaitable; Atomic nanmin and nanmax functions are added; Fixes for various miscompilations and segfaults. (mostly Graham Markall; call backs on streams by Peter Würtz).
Intel also kindly sponsored research and development that lead to some exciting new features:
Support for heterogeneous immutable lists and heterogeneous immutable string key dictionaries. Also optional initial/construction value capturing for all lists and dictionaries containing literal values (Stuart Archibald).
A new pass-by-reference mutable structure extension type StructRef (Siu Kwan Lam).
Object mode blocks are now cacheable, with the side effect of numerous bug fixes and performance improvements in caching. This also permits caching of functions defined in closures (Siu Kwan Lam).
Deprecations to note:
To align with other targets, the argtypes and restypes kwargs to @cuda.jit are now deprecated, the bind kwarg is also deprecated. Further the target kwarg to the numba.jit decorator family is deprecated.
